I’m an outsider; what does “precision” refer to in fine chemical engineering? This post was last edited by zxh6267 on 2009-3-13 21:04.]
Fine chemicals industry is a general term for the industry that produces fine chemicals. The meaning of fine chemicals is still under discussion abroad to this day. Currently, chemical products that possess the following characteristics are generally referred to as fine chemicals, namely: 1. A large variety of products, with rapid updates ; 2. Low output, with production mostly occurring in intermittent fashion ; 3. Functional or for end-use purposes ; 4. Many are composite products, and their performance is determined by formulation and other technical factors ; 5. High requirements for product quality ; 6. High commerciality, with most being sold under brand names ; 7. High technology intensity, requiring continuous technical development of new products and research on application technologies, with an emphasis on technical services ; 8. Lower equipment investment ; 9. High value-added rate, etc.
The term \"fine chemicals\" has been in use for a long time; it originally referred to chemical products with low production volumes, high purity, and high prices, such as pharmaceuticals, dyes, and coatings. However, this meaning has not fully revealed the essence of fine chemicals. In recent years, experts from various countries have developed new perspectives on the definition of fine chemicals. In Europe and the United States, certain chemical substances that are produced in small quantities and manufactured and sold based on their distinct chemical structures are referred to as fine chemicals ; Products that have low production volumes, are formulated through processing, possess specific functions, or have particular performance characteristics are known as specialty chemicals. China, Japan, and other countries collectively refer to these two types of products as fine chemicals. There is a wide variety of fine chemicals, including inorganic compounds, organic compounds, polymers, and their complexes. The common characteristics in production technology are as follows: ① There is a large variety of products, and they are updated rapidly; therefore, continuous technical and application development of these products is required, which results in high research and development costs. For example, the research expenses in the pharmaceutical industry often account for 8% to 10% of the sales revenue from drugs. This results in strong technical monopolies and high sales profit margins. ②The product quality is stable; high purity is required for the original material. After blending, it is necessary not only to ensure the physical and chemical properties but also to pay close attention to the performance in use. Various testing methods are often required to conduct different usage tests. These tests have long durations and complex equipment, and many of them involve human safety and environmental impacts. Therefore, there are many regulations and standards for the management of fine chemical products. Such as pharmacopoeias (see the Pharmacopoeia of the People’s Republic of China, the British Pharmacopoeia), regulations on pesticide management, etc. For products that do not meet the requirements, they are often **ordered to make improvements in order to meet the specified standards, or production is prohibited. ③The production process of fine chemicals differs from that of conventional chemicals; it encompasses not only chemical synthesis (or separation and extraction from natural substances) but also formulation processing and commercialization, and is thus composed of two parts. In the chemical synthesis process, basic chemical raw materials are used to produce intermediates, which are then used to manufacture various fine chemicals such as pharmaceuticals, dyes, pesticides, organic pigments, surfactants, and fragrances. The formulation and commercialization processes are the techniques for preparing various products into market-ready forms, and their processing technologies all involve broadly similar unit operations. ④It is mostly produced in small batches on an intermittent basis. Although the production process is long, the scale is small, the investment cost for individual equipment is low, and precise engineering techniques are required. ⑤Products have a strong commercial nature, and competition among users is fierce; therefore, research and production entities must possess comprehensive application technologies to provide technical services to users.
Thank you for the introduction from the 3rd floor; I’ve learned something! :lol

The fine chemicals industry (abbreviated as fine chemical industry) is a general term for the industry that produces fine chemicals; to date, there is no precise definition for it. In Japan, some people have provided the following definitions of “fine chemicals”: 1. From the perspective of products, they refer to chemical products that require advanced manufacturing techniques and application research, feature low production volumes but a large variety of types. 2. Proposed from the perspective of product added value and technical intensity: high added value and high quality
\"Fine\" in English refers to products that are produced in small quantities but have a high added value; examples include additives, auxiliaries, perfumes, and cosmetics. The same is true for the chemical industry; the specialty chemicals program in our school is essentially related to coatings technology, and in the past, working in the coatings industry was very profitable
Short for the fine chemicals industry, the economic sector of the chemical industry that produces fine chemicals. The term \"fine chemicals\" has been in use for a long time; it originally referred to chemical products with low production volumes, high purity, and high prices, such as pharmaceuticals, dyes, and coatings. However, this meaning has not fully revealed the essence of fine chemicals. In recent years, experts from various countries have developed new perspectives on the definition of fine chemicals. In Europe and the United States, certain chemical substances that are produced in small quantities and manufactured and sold based on their distinct chemical structures are referred to as fine chemicals ; Products that have low production volumes, are formulated through processing, possess specific functions, or have particular performance characteristics are known as specialty chemicals. China, Japan, and other countries collectively refer to these two types of products as fine chemicals. Fine chemicals differ from basic chemicals (such as basic organic and inorganic chemicals); the latter mainly produce basic chemical raw materials, whereas the products manufactured by fine chemicals are typically auxiliary materials widely used in various industrial sectors or direct consumer goods for people’s daily lives. Therefore, fine chemicals are an indispensable industrial sector of the national economy, and they are closely linked to people’s lives. Classification: Due to the varying classification methods in different countries, the scope of fine chemicals also varies. At present, fine chemicals in China generally include: pharmaceuticals, pesticides, dyes, coatings, pigments, chemicals for information technology (including photosensitive materials, magnetic recording materials, etc.), chemical reagents and high-purity substances, food additives, feed additives, catalysts, adhesives, auxiliaries, surfactants, fragrances, and so on. With the development of the national economy, the fields of development and application for fine chemicals will continue to expand, and new categories will keep emerging. Features There is a wide variety of fine chemicals, including inorganic compounds, organic compounds, polymers, and their complexes. The common characteristics in production technology are as follows: ① There is a large variety of products, and they are updated rapidly; therefore, continuous technical and application development of these products is required, which results in high research and development costs. For example, the research expenses in the pharmaceutical industry often account for 8% to 10% of the sales revenue from drugs.

Current situation of the world: The most developed countries in the global fine chemicals industry are the United States, West Germany, and Japan, which rank first, second, and third in terms of product production respectively. Fine chemicals in the United States: New categories kept emerging, and in the 1960s the U.S. developed water treatment agents ; The sharp rise in oil prices in 1973 forced oil companies to explore new oil and gas resources, and oilfield chemicals thus became popular products. At the end of the 1970s, with the rapid development of the electronics industry, reagents for use in this industry once again became a focus. In 1982, sales of specialty chemicals in the United States were highest for agricultural chemicals and oilfield chemicals. Bundeng De Fine Chemicals: Since the 1970s, it has adopted a so-called \"strategy of differential growth,\" which involves selectively and strategically developing fine chemical products that possess its own unique features and technical advantages, thereby continuously increasing the sales volume of such products. The main producers in the world are several well-known large chemical companies, such as DuPont in the United States (where the proportion of fine chemical production exceeds 50%), Bayer AG in West Germany, and Sumitomo Chemical Industries in Japan. China’s fine chemicals industry has a weak foundation, but its production volume has been growing rapidly in recent years. In 1985, China produced 89kt of dyes, 79kt of pharmaceuticals (12 major categories of chemical active ingredients), 205kt of pesticides, 769kt of coatings, and 170Mm of film stock. Chemical reagents (value of production in 1983): nearly 500 million yuan; adhesives (1983): 110 kt; plasticizers (1983): 215 kt; detergents (1983): 670 kt; tapes (1984): approximately 240 Mm.
