For a 150,000 tons/a device, what kind of downstream products would be better to develop?

The investment in chloroacetic acid is relatively small, and the downstream consumption of chloroacetic acid is also relatively large.； The current PVC market is not very good, and the investment is huge. Now there are more companies launching PVC.

At present, the market of chloroacetic acid is also divided into regions. Our company is not very good now. It depends on the specific sales of your caustic soda and chlorine. If the sales are really not good, you have to develop downstream production and sales that are better. As for small scale, phosphorus trichloride is actually not bad, with small scale, low investment, and the current market is not bad.

Depending on the local market, you may consider phosphorus trichloride or trichlorosilane.

You can see if there are any units nearby that you can cooperate with. Whether it is chloroacetic acid or phosphorus trichloride, they mainly make glyphosate. If there are glyphosate manufacturers nearby, it would be best to cooperate. If it is far away, there will be no future. For example, phosphorus trichloride is a high-risk product and the transportation cost is high. Downstream manufacturers have no advantage if they are far away.

Alkali- and chlorine-consuming products mainly include instant layered sodium metasilicate, high-viscosity sodium carboxymethyl starch, sodium diacetate, chloroisocyanuric acid, sodium formate, oxalic acid, epichlorohydrin, water and hydrazine, ADC foaming agent, insurance powder, chlorinated polyvinyl chloride, chlorinated polypropylene, chlorinated rubber, chlorinated paraffin-70, etc. With a scale of 150,000 tons, we cannot expect to develop a single downstream fine chemical product. If we have strong technical strength and market conditions allow, achieving product diversification is the only way to develop.

Trichlorosilane can be considered for chlorine consumption, and polycrystalline silicon raw materials have good prospects.； For chloroacetic acid, it is best to cooperate with a glyphosate manufacturer ； Hydrogen peroxide can be considered for hydrogen consumption, and so can product profits.

Propylene oxide is okay as long as the raw materials are guaranteed. Trichlorethylene is good and profitable, but it is currently a confidential project.

There are many projects that consume chlorine and hydrogen. I think the actual situation of each manufacturer is different, and no one project is suitable for everyone. Therefore, based on the actual situation, the industrial environment of the region, raw material conditions, etc., the key is to find a project suitable for your own development.

The trichlorosilane produced in our factory has a simple process, earns money quickly, and requires few people. It is also quite dangerous, flammable and explosive.

Product properties of chlorine-consuming products, thionyl chloride: Thionyl chloride, also known as thionyl chloride or sulfur oxychloride, has a molecular formula of SOCl2 and a molecular weight of 118.97. It is a colorless or light yellow liquid under normal temperature and pressure, with a pungent odor. The relative density is 1.676, the melting point is -104.5℃, and the boiling point is 78.8℃. It easily decomposes into sulfur dioxide and hydrogen chloride when exposed to water. Soluble in benzene, chloroform and carbon tetrachloride. Its chlorine atom has a remarkable ability to replace hydroxyl or sulfur groups. Thionyl chloride can react with phenols or alcohols with hydroxyl groups to form the corresponding chlorides ； Reacts with Grignard reagent to generate the corresponding sulfoxide compound. Application areas: Thionyl chloride is an important organic chemical intermediate, mainly used in pharmaceutical, pesticide and dye industries. The consumption structure is: The pharmaceutical industry accounts for 25%, the pesticide industry accounts for 50%, the dye industry accounts for 5%, and other industries account for 20%. production method: At present, there are three main industrial production methods of sulfoxide chloride: chlorosulfonic acid method, sulfur dioxide gas phase method and phosphorus oxychloride co-production method. consumption quota: Production method raw materials and specifications consumption quota/t•t-1 Chlorosulfonic acid method Chlorosulfonic acid (95%) Liquid chlorine (99%) Sulfur powder (99.5%) 1.1 0.91 0.42 Sulfur dioxide gas phase method sulfur (99.5%) Liquid chlorine (99%) Sulfur dioxide (99%) 0.22 0.88 0.44 Co-generation method phosphorus trichloride (98%) liquid chlorine (99%) sulfur dioxide (99%) 1.3 0.66 0.64 Manufacturer: The largest manufacturer of sulfoxide chloride in my country is Shandong Kaisheng Biochemical Co., Ltd., 35,000 tons. In addition, there are Jiangxi Dianhua Fine Chemical Co., Ltd., Changzhou Xudong Chemical Co., Ltd., Zhejiang Lanxi Kaipu Chemical Co., Ltd., Tongling Kaixing Synthetic Materials Co., Ltd., Sichuan Boxing Industrial Co., Ltd., Jiangsu Xuzhou Jianping Chemical Co., Ltd., Shangyu Wolong Chemical Co., Ltd., Zhejiang Jiaxing Solvent Factory, etc. At present, there are nearly 20 manufacturers of thionyl chloride in my country, with a total production capacity of approximately 108,600 tons/year, a total output of approximately 40,000 tons/year, and an apparent consumption of approximately 22,000 tons/year. Industry status: In recent years, most of the newly built thionyl chloride production units in my country adopt the vapor dioxide phase method or the phosphorus oxychloride co-production process. The original production equipment using the chlorosulfonic acid method are generally old equipment and are equipped with their own chlorosulfonic acid production equipment. In recent years, most of the manufacturers in my country that use the chlorosulfonic acid method to produce thionyl chloride have had to reduce or stop production due to high production costs, and their products are mostly secondary industrial products of poor quality. The market prices are low, and the economic benefits of the enterprises are poor. In addition, environmental problems are also serious and they have to reduce or stop production. This has resulted in a large gap between the actual output and production capacity of thionyl chloride in my country. It is expected that in the next few years, my country's demand for thionyl chloride will grow at an average annual rate of about 6.7%, and the total demand will reach about 23,000 tons/year by 2007. Chloroacetic acid product properties: Chloroacetic acid, also known as monochloroacetic acid, has the molecular formula C2H3ClO2. It is a bifunctional compound. It is colorless or light yellow crystal with a pungent odor. Boiling point (760mmHg) -188℃, refractive index 1.4330 (60℃), melting point: 61~63℃, corrosive, acidic reaction in aqueous solution. Chloroacetic acid is easily deliquescent and soluble in water, alcohol, benzene, chloroform and ether. The solubility in 100g of water at 25°C is 510g, and the solubility in 100g of methanol is 350g. Chloroacetic acid has a pungent odor and is a secondary acid corrosive substance. The oral LD50 of rats is 76mg/Hg, and the oral LD50 of guinea pigs is 80mg/Hg. Application areas: Chloroacetic acid is widely used in pesticides, medicines, dyes, daily chemicals, surfactants, chemical reagents, papermaking chemicals, oilfield chemistry, textile auxiliaries, rubber auxiliaries, electroplating, flavors and fragrances, etc. Global chloroacetic acid is mainly used to produce carboxymethylcellulose (CMC), PVC heat stabilizer thioglycolic acid, 2,4-chlorophenoxyacetic acid (2,4-D), etc. The main consumption areas of chloroacetic acid in my country are pesticides and pesticide industries. Chloroacetic acid can synthesize more than 20 kinds of commonly used insecticides, herbicides and plant production regulators. Among them, the species that consumes the largest amount of chloroacetic acid is the mainstream herbicide glyphosate used globally. consumption quota: Main consumption of raw materials and power (based on 1 ton of chloroacetic acid) Name Specification Consumption Acetic acid acetic anhydride liquid chlorine ≥98% ≥98% ≥99.5% 0.597t 0.069t 0.809t Water - 125t Electricity - 320kW.h Steam - 2.1t manufacturer: At present, China and Western Europe have become the world's major chloroacetic acid production regions and * * . Major domestic chloroacetic acid production companies include AkzoNobel Chloroacetic Acid Chemical (Taixing) Co., Ltd., Jiangsu Wuxi Green Aip Chemical Co., Ltd., Henan Kaifeng Dongda Chemical Group Co., Ltd., Hebei Shijiazhuang Synthetic Chemical Factory, Shandong Huayang Group, Dalian Landison Chemical Co., Ltd., etc. Industry status: my country's chloroacetic acid production started relatively late. It was not until the mid-1980s that, with the development of my country's petroleum industry, the amount of carboxymethylcellulose, a drilling additive, increased significantly, and my country's chloroacetic acid production began to develop. The rapid development of pesticides and herbicides in my country in the early 1990s once again stimulated the development of the chloroacetic acid industry. During this period, my country successively built multiple sets of chloroacetic acid production units. In July 1991, a 500-ton/year chloroacetic acid production unit using acetic anhydride as a catalyst at the Dongtai Organic Chemical Plant in Jiangsu Province was completed and put into operation, setting a precedent for the production of chloroacetic acid by the acetic acid chlorination method in my country. In 1999, China's first large-scale chloroacetic acid production unit using the acetic anhydride catalytic method was completed and put into operation at Jiangsu Wuxi Green Aip Chemical Co., Ltd., with a production capacity of 5,000 tons/year. In 2004, the production capacity was expanded to 25,000 tons/year, and the product quality index reached 97.5% to 99.5%. In December 1999, Taixing City, Jiangsu Province signed a contract with the world's largest chloroacetic acid production company AkzoNobel of the Netherlands to build a chloroacetic acid production unit with an annual output of 25,000 tons in the Taixing Economic Development Zone. The project was completed and put into operation in June 2002, and the product quality index can reach 99.9%. After these devices were put into production, they greatly promoted the development of my country's chloroacetic acid industry. In recent years, global production and consumption of chloroacetic acid have basically maintained a balance. Rapid demand growth in Western Europe has been slowing down. Japan's domestic demand has continued to be sluggish in previous years. Demand in Oceania and Central and Eastern Europe has maintained a steady growth trend. Demand in Central and South America has grown rapidly. Domestic demand has grown rapidly in the United States since 2001. At present, China and Western Europe have become the world's most important chloroacetic acid production regions and * * , with the exception of China, global production is increasingly concentrated. AkzoNobel, Clariant, DowChemicals, etc. control the global production, supply and trade of chloroacetic acid. Currently, Western Europe is the main export region of chloroacetic acid in the world. In addition, Japan and China also have a certain amount of exports. ； The United States, Eastern Europe, and Central and South America have become important global import regions for chloroacetic acid. Some insiders pointed out that my country has become the world's major producer and consumer of chloroacetic acid. The scale, production capacity and technical level of chloroacetic acid equipment have made great progress. However, compared with developed countries abroad, * * Compared with regions, there is still a large gap compared with domestic fine chemical industry development requirements, and the existence of industry contradictions is also an objective phenomenon. Methane chloride product properties: Methane chloride is the general name for four products, including methyl chloride (methyl chloride), methylene chloride, chloroform (also known as chloroform), and carbon tetrachloride, referred to as CMS. It is the bulk chlorine-based product second only to vinyl chloride among organic products and is an important chemical raw material and organic solvent. The different ratios of chlorine and methane determine the production ratio of monochlorine to tetrachlorine. When the molar ratio of chlorine to methane is 0.8:1, monochloromethane is produced the most. ； When the molar ratio of chlorine to methane is 2.6:1, chloroform is mainly produced ； When the molar ratio of chlorine to methane is 3.6-3.8:1, carbon tetrachloride is mainly generated. Application areas: As the raw material of methylchlorosilane, more than 85% of methyl chloride is used in the production of silicone (basically self-produced for self-use), and is also used in the production of methylcellulose and other products ； Dichloromethane is mainly used in medicines and pesticides. It can be used as a polyurethane foaming agent instead of CFC11, as a binder solvent instead of benzene and xylene. It can also be used in the metal cleaning and electronic cleaning industries. In recent years, it has been used as a raw material for the production of refrigerant HFC32. ； Trichloromethane is an excellent organic solvent, mostly used as a raw material for the production of HCFC-22 and polytetrafluoroethylene. Trichloromethane is also an excellent organic chlorine solvent. ； Carbon tetrachloride is mainly used in the production of HCFC-11/12 and organochlorine solvents. production method: Methanol method and methane method are mainly used to produce monochloromethane, methylene chloride and chloroform abroad. There are many methods used to produce carbon tetrachloride, including deep chlorination using ethanol or methane as raw materials, chlorination of carbon disulfide, and high-temperature chlorination of C1~C3 to produce two products: carbon tetrachloride and tetrachlorethylene. Sidhes Company has also developed a technology that uses hydrocarbon waste and its greening derivatives as raw materials to produce carbon tetrachloride and by-product hydrogen chloride through chlorolysis reaction under high temperature and pressure. The reaction pressure is 5Mpa and the temperature is 620°C. There are currently devices in production in France and Europe. The Italian Montreal company adopts a high-temperature thermal chlorination method of vinyl chloride waste gas and waste liquid to produce carbon tetrachloride and co-produce tetrachlorethylene. The reaction conditions are relatively mild. The reaction temperature is 525℃~580℃, and the reaction pressure is 0.07~0.082Mpa. This technology has been transferred to Shanghai Chlor-Alkali in my country and has been officially put into production. A low-temperature liquid-phase chlorination method of monochloromethane developed by Japan's Tokuyama Soda Company to produce dichloromethane, chloroform, and carbon tetrachloride has the advantages of high product quality, low raw material consumption, low energy consumption, and long operation cycle. my country's first imported device was Zhejiang Juhua, which introduced a methanol-based device for producing chloroform and carbon tetrachloride in 1993. The product quality and raw material consumption reached the internationally advanced level. Jiangsu Meilan introduced technology and key equipment in the late 1990s and built a 30.8kt/a methylene chloride and chloroform production unit using the methanol method. Sichuan Honghe uses the natural gas thermal chlorination method (it has its own intellectual property rights). Luzhou North has independent property rights of methanol production equipment for chloroform and carbon tetrachloride. consumption quota: Methyl chloride (kg/t) Raw materials and specifications Methane chlorination method Methanol method Natural gas 640m3 - Chlorine 2000～2200 - Methanol - 740 Hydrogen chloride - 850 Dichloromethane (kg/t) Raw materials and specifications Natural gas method Methyl chloride method Natural gas (containing CH497%) 1000m3 - Chlorine (100%) 4000 854 Liquid caustic soda (100%) 274 221 Methyl chloride (98%) - 246 chloroform (kg/t) Raw material name Methane method Methanol method natural gas 290m3 - Chlorine 2540 -1500 Caustic soda ~ 300 - Methanol - -400 Carbon tetrachloride (kg/t) Raw materials and specifications Methane chloride methanol method natural gas (containing CH498%) 800m3 - Chlorine (95%) 2600～2900 1650 Methanol - 400 Manufacturer: At present, except for Zigong Honghe Chemical, which retains 30,000 tons/year of natural gas thermal chlorination production equipment, other domestic enterprises use the methanol method to produce methane chloride. It is understood that the product ratio of dichloromethane and chloroform is 30 to 60: 40-70. In 2005, my country's methane chloride production capacity was approximately 662,000 tons/year, with an output of 570,400 tons. In 2007, the methane chloride device capacity reached 1.022 million tons per year, and the output reached 815,000 tons. It can be seen that the methane chloride industry is rapidly moving forward on a 20% growth base. The main methane chloride companies in my country include Jiangsu Meilan Chemical Co., Ltd., Zhejiang Juhua Group, Shandong Jinling Chemical Co., Ltd., China Haohua Group Southwest Branch, Shandong Dongyue Fluorosilicone Materials Co., Ltd., etc. Industry status: Our country’s economy has grown rapidly this year, and methane chloride has * * The rapid development of the industry, coupled with the adoption of anti-dumping measures against methylene chloride and chloroform, has ushered in a golden period of development for the domestic methane chloride industry. In 2008, the production capacity is expected to reach 1.182 million tons, and the output will exceed 900,000 tons. In addition, with the rapid growth of domestic market demand for methane chloride, foreign companies are competing to join, intensifying competition in the domestic market. In 2000, my country's import volume of methane chloride was 189,600 tons, reaching 300,000 tons in 2004. It has shown a downward trend since 2005, and still reached 230,000 tons in 2006. In 2007, the annual import volume also exceeded about 190,000 tons. Some foreign companies export large quantities of methane chloride to my country through processing trade, and then purchase large quantities of R22, R32, PTFE and other products from my country at low prices, which consumes my country's limited fluorine resources and is not conducive to * * Protection of resources. However, due to the rapid expansion of methane chloride production capacity in China, the output has far exceeded the domestic market demand. Due to the uneven expansion of production capacity in various regions, market competition has become increasingly fierce. Major domestic manufacturers are engaged in price wars in major consumer markets, forming a vicious circle. As far as the domestic methane chloride industry is concerned, seeking new markets to shift the contradiction between domestic supply and demand is the key to future work. Judging from the price trend of the domestic methane chloride market in recent years, the profit margins of the methane chloride industry are gradually shrinking. Relevant domestic enterprises should not blindly build new methane chloride devices. It is recommended to conduct detailed project competitiveness analysis based on in-depth analysis of market conditions, raw material supply and technology sources, and encourage joint ventures and cooperation with existing methane chloride enterprises to achieve the goals of complementary advantages, resource sharing, and common development, and form a situation of orderly competition in the methane chloride industry. Epichlorohydrin product properties: Epichlorohydrin is also known as "3-chloro-1,2-epoxypropane". The pure product is a colorless oily liquid, easily volatile, with an odor similar to ether and chloroform. The relative density is 1.1807, the boiling point is 116.2℃, and the freezing point is -57.2℃. It is soluble in water, ether, alcohols, carbon tetrachloride and benzene at room temperature and is toxic. The maximum allowable concentration in the air is 5×10-6. Application areas: Epichlorohydrin is an important organic chemical raw material and fine chemical product with a wide range of uses. The epoxy resin made from it as raw material has the characteristics of strong adhesion, resistance to chemical medium corrosion, good chemical stability, high impact strength and excellent dielectric properties. It is widely used in coatings, adhesives, reinforcement materials, casting materials and electronic laminates and other industries. At present, there are two main industrial production methods for epichlorohydrin: high-temperature chlorination of propylene and propylene acetate. production method: There are two methods for producing epichlorohydrin. The first is the high-temperature chlorination method of propylene. Propylene is used as raw material, and 3-chloropropene is obtained through high-temperature chlorination. The hypochlorous acidification reaction generates dichloropropanol, and alkali (caustic soda or milk of lime) is added for cyclization. The second method is the propylene acetate method. Propylene is oxidized in the presence of a catalyst and acetic acid to form propylene acetate, hydrolyzed to form propylene alcohol, chlorinated to form dichloropropanol, saponified to obtain epichlorohydrin, and distilled to separate and remove heavy components to obtain the product. consumption quota: (kg/t) Name of raw material Domestic technology imported technology Propylene acetate method Propylene (95%) 1000～1100 720 620 Chlorine (99%) 1600 2200 920 Soda ash (95%) 800～1000 - - Caustic soda (42%) 700～1000 1130 (slaked lime) - Oxygen - - 276(㎡) Manufacturing company: Shenyang Chemical Industry, Yuehua General Plant Epoxy Resin Plant, Wuxi Resin Plant, Qilu Petrochemical Corporation Chlor-Alkali Plant, Bohai Chemical Group Tianjin Chemical Plant, Shandong Province Dongying City Chemical Plant. Industry status: At present, the total consumption of epichlorohydrin in the world is about 1.2 million tons per year. The products are mainly used to produce epoxy resin, synthetic glycerin, chlorohydrin rubber and glycidyl ether, among which the consumption of epoxy resin accounts for about 75% of the consumption. The main exporting countries of epichlorohydrin are Japan and the United States, and the main imported cars are Asia and Eastern Europe. It is expected that the demand for epichlorohydrin will grow at an average annual rate of about 5% to 6% in the next few years.

The process of producing hydrogen from natural gas is very mature and eliminates excess chlorine. This is what our unit does, using the technology of the Eighth Hospital.

I suggest using phosphorus trichloride. It has small investment, mature technology and large dosage.

Trichlorosilane and trichlorethylene projects are relatively good projects with small investments and large returns.

For the project upstairs, the safety and environmental impact assessment is very troublesome, and the production process is very dangerous and toxic. It is recommended to launch chlorinated polymers and specialize in the production of rubber-type chlorinated polyethylene. You can contact me healthran@163.com

First, look at how much chlorine can be consumed by the surrounding market. In fact, the transportation of chlorine is very troublesome. For such a project, it is best to introduce chlorine downstream manufacturers to build factories nearby, and direct pipeline transportation is the best. Downstream products are mainly in several directions: Trichlorosilane, silicon industry products, can be extended to polycrystalline silicon, monocrystalline silicon, solar energy, semiconductors and other chloroacetic acid chloromethane, extended to the fluorine chemical industry phosphorus trichloride, extended to bisglyphosate and other sodium hypochlorite, mainly supporting, such as hydrazine hydrate, chlorinated paraffin, and other fine chemicals

Benzyl chloride co-produces benzaldehyde. There are currently relatively few domestic production units of benzyl chloride. You can consider improving the technology in Belgium and adjust the amount of co-produced benzaldehyde at will. The current benzaldehyde market is very good and is more suitable for domestic enterprises.

In Zibo? To develop chloroacetic acid products, the current market gap is about 200,000 tons. You have such a good raw material advantage, and you can produce 20,000 tons of chloroacetic acid in Zibo every year. Weifang Binhai District can handle about 40,000 tons, and we will look at other areas. I heard that Weifang Binhai District is preparing to launch a 100,000-ton production device, so it’s better to start first!

Alkali- and chlorine-consuming products mainly include instant layered sodium metasilicate, high-viscosity sodium carboxymethyl starch, sodium diacetate, chloroisocyanuric acid, sodium formate, oxalic acid, epichlorohydrin, water and hydrazine, ADC foaming agent, insurance powder, chlorinated polyvinyl chloride, chlorinated polypropylene, chlorinated rubber, chlorinated paraffin-70, etc. With a scale of 150,000 tons, we cannot expect to develop a single downstream fine chemical product. If we have strong technical strength and market conditions allow, achieving product diversification is the only way to develop.

40,000 t/a Chlorotoluene 1 Project Introduction Chlorotoluene is an important fine chemical raw material. In recent years, a variety of new medicines, pesticides, dyes, etc. intermediates have used chlorotoluene as starting raw materials. These intermediates have shown very bright development prospects. Domestic and foreign markets are unanimously optimistic, and many intermediates have become hot development products. The huge development space in the downstream market has stimulated and promoted the production and development of chlorotoluene, and chlorotoluene will become the new favorite of organochlorine products. There are three isomers of chlorotoluene, namely p-chlorotoluene, o-chlorotoluene, and m-chlorotoluene. The main products are p-chlorotoluene and o-chlorotoluene, and the output of m-chlorotoluene is very small. In recent years, with the acceleration of the construction of chlorotoluene production equipment in my country, foreign chlorotoluene production has gradually shrunk. In 2006, the global chlorotoluene production capacity was 191,000 t/a, of which China's production capacity was approximately 117,000 t/a. Major foreign production companies include Germany's Bayer Company, Belgium's Tessenderlo Group, Japan's Ihara Company, Japan's Hod2 26 Product Chlor-Alkali Industry 2008ogy Company, and the UK's Widnes Company. India has a production capacity of approximately 20,000 t/a. In 2000, the U.S. Western Chemical Company closed its 32,000 t/a chlorotoluene production unit, resulting in a tight global supply of chlorotoluene. Coupled with strong domestic downstream demand, domestic chlorotoluene has developed rapidly in recent years, and many units were completed and put into operation in 2004-2005. At present, the main chlorotoluene manufacturers in my country are: Jiangsu Xinye Chemical Co., Ltd., Danyang Zhongchao Chemical Co., Ltd., Jiangsu Zhongteng Chemical Co., Ltd., Zibo Aoda Chemical Co., Ltd., Jiangsu Hongxing Chemical Co., Ltd., Hunan Zhuzhou Chemical Group Co., Ltd., etc. At present, the vast majority of domestic chlorotoluene production companies do not have chlor-alkali equipment. Except for Hunan Zhuzhou Chemical Group Company, they all need to purchase chlorine gas for production, and the competitiveness of the equipment is not strong. In 2007, my country's output of chlorotoluene was about 80,000 tons, exports of p-chlorotoluene were very small, and exports of o-chlorotoluene were relatively large (there is currently no customs statistics). According to estimates by major manufacturers, domestic export volume of o-chlorotoluene in 2008 was approximately 10,000 tons. In 2007, the domestic consumption of chlorotoluene was about 70,000 tons, and the consumption proportion was roughly as follows: the pharmaceutical industry accounted for 35%, the pesticide industry accounted for 30%, dyes and pigments accounted for 25%, and spices and others accounted for about 10%. With the continuous development of downstream products of chlorotoluene, the market demand for chlorotoluene has grown steadily. It is expected that my country's demand plus export volume of chlorotoluene will reach 120,000 tons in 2010. 2. Technology source: The industrial synthesis of chlorotoluene mainly adopts the direct chlorination method using toluene as raw material. The key technology lies in the separation of isomers and output adjustment. At present, the relatively mature and advanced technology in China is toluene chloride distillation and crystallization technology, which has been used by many production companies. Several scientific research institutions such as Nanjing University of Technology, Dalian University of Technology, and Tianjin University have mastered mature industrial production technologies. The main raw materials for the production of chlorotoluene are chlorine and toluene, and the consumption is: toluene 755 kg/t, chlorine 590 kg/t. 3 Investment estimate The fixed asset investment of the project is approximately 60 million yuan. After completion, the annual sales revenue will be approximately 350 million yuan, the average annual total profit will be approximately 24 million yuan, and the investment profit rate will be 40.0%. 4. Safety and environmental protection. The chlorotoluene synthesis technology is relatively mature. A certain amount of wastewater generated during the production process can be treated with resin, which has good safety and stability. 5 Investment Description In recent years, many new varieties of pesticides and dyes use chlorotoluene as the basic raw material. The market for many chlorotoluene downstream fine chemical intermediates and fine chemicals is in the growth stage, and the prospects are very promising; most domestic chlorotoluene companies do not have supporting chlorine equipment, and are small in scale and not very competitive. Domestic chlor-alkali companies can build chlorotoluene production bases with the help of chlor-alkali equipment, and at the same time stimulate the development of local new pesticide, pharmaceutical and dye industries. In addition, it is necessary to increase the development of downstream products and form an industrial chain of new high value-added fine chemicals based on chlorotoluene.
