Who has information on the technology, market, companies, and economic benefits of trimethylolpropane, both domestically and internationally?

The Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences, has successfully carried out industrial trials of a technology using ion liquid catalysts to produce trimethylolpropane; this method is more environmentally friendly and cost-effective than the traditional sulfuric acid process

Although I am not familiar with LICP-based ionic liquids, I personally believe that such ionic liquids are unlikely to be commercialized in large-scale industrial facilities such as those in the petrochemical industry in the near future. Industry experts have provided many insightful analyses on the reasons. It might be feasible in industries that use small quantities of drugs or cosmetics, operate on a non-continuous basis, and have high added value for their products. Three years ago, I conducted research on a large number of foreign ion liquids. In conclusion, for petrochemical producers, developing ionic liquid processes is purely a waste in the foreseeable future – a waste of time and money.

Where can I find the relevant comments from three years ago? Could the analysis in this regard be elaborated on?

The issue of ion liquid loss hasn’t been resolved yet, and costs are very high in this regard

Don’t be deceived by appearances; industrialization of ionic liquids still requires effort.

In fact, all new things need time to be proven!

It seems not many people understand this thing

I’m only aware of all the latest technologies at Lanzhou Chemicals, but I’m not very familiar with the market aspect. I have also been keeping an eye on this product.

China’s first 10,000-ton-scale DMM3-8 (polymethoxydimethyl ether) plant, developed independently with full domestic intellectual property rights, has been operating continuously and stably since its successful commissioning on July 26 at Shandong (Heze) Chenxin New Energy Company; the selectivity of this plant is close to 50%. This not only marks China’s leadership in the world in mastering the DMM3-8 production technology, but also signifies a major breakthrough in the downstream development of methanol in China, opening up new avenues for addressing the surplus methanol capacity. 　　This technology uses methanol as a raw material and an ionic liquid as a catalyst to synthesize DMM3-8 from trioxane. This project is a key project and a priority project under the **12th Five-Year Plan for Science and Technology Support. By optimizing the synthesis and separation/purification processes of triomethylenemethane, developing the process for synthesizing DMM3-8 from methanol, innovating and improving key engineering technologies such as continuous catalytic synthesis and separation, as well as carrying out system integration and process intensification, the researchers verified the technical reliability and system stability of the method for producing DMM3-8 from methanol. 　　In collaboration with the Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences, the company built the world’s first 10,000-ton-scale DMM3-8 industrial demonstration plant. The methanol utilization rate of the device reaches 85%, the conversion rate of paraformaldehyde is greater than 90%, and the selectivity for DMM3-8 is close to 50%. 　　The physical properties of DMM3-8 are similar to those of diesel, and it is highly miscible with diesel; therefore, no modifications to the vehicle engine’s fuel supply system are required when using it in diesel. It has a cetane number as high as 76, an oxygen content of 47%-50%, and is free of sulfur and aromatic compounds. When blended at 10%-20% in diesel, it can significantly lower the dew point of diesel, improve its combustion properties, and increase thermal efficiency. It can reduce smoke density by up to 80% and nitrogen oxides by 50%; it is internationally recognized as a new type of environmentally friendly diesel additive that helps reduce fuel consumption and exhaust emissions. At the same time, DMM2, DMM3, and DMM4 are also solvents with extremely strong dissolving capabilities, offering broad application prospects. 　　In our country, alone the diesel used for transportation exceeds 150 million tons per year; if 15% is added to it, the annual demand for DMM3-8 will exceed 22.5 million tons. It is understood that approximately 1.5 tons of methanol are consumed per ton of DMM3-8, and if large-scale production is achieved, it is expected to use nearly half of the country’s methanol production capacity each year. The successful development of DMM3-8 technology provides important technical support and an effective solution to alleviate the severe overcapacity issue in methanol production in our country at present.

According to a report from Sinochem New Network, on January 10, the pilot-scale polyformaldehyde production plant was successfully put into operation for the first time at CNOOC Chemical Co., Ltd. (Hainan Dongfang). The Chinese Academy of Sciences’ Lanzhou Institute of Chemical Physics was responsible for key technologies related to catalysts and catalytic reaction processes, Fuyi International Engineering Company handled the pilot-scale design, while CNOOC Chemical was in charge of building the pilot-scale installation and carrying out testing – and qualified polyformaldehyde was produced as a result. It marks the successful industrial-scale trial of the world’s first use of ionic liquid catalysts for the synthesis of trioxane, representing a major breakthrough in the commercialization of technologies with independent intellectual property rights developed by the Lanzhou Institute of Chemical Physics. 　　The design of this facility is based on scaling up the laboratory-scale pilot reaction process developed by Lanzhou Institute of Chemical Physics to a scale of 2,000 tons, with a scaling factor of over 40,000 times ； The LZT-Ⅰ type ionic liquid catalyst, which can be produced in batches, was also used. This test run completed the entire process, evaluated the rationality of the design, replicated the laboratory research results, and highlighted the integration of innovations in key core technologies and system technologies. This project received support from the key project under the **11th Five-Year Plan’s Science and Technology Support Program, namely ‘Technology for the Comprehensive Utilization of Bulk Oxo Compounds via Non-petroleum Routes’, as well as from the Chinese Academy of Sciences’ major strategic project ‘New Technologies for the Clean Synthesis of Trioxane’. 　　The project completed laboratory testing in 2006, the equipment design was finalized in 2007, and it was completed in October 2008. On the day of the trial run, Mr. Zhang Xinzhi, a guest expert, Researcher Xia Chungu and Researcher Chen Jing, deputy directors of Lanzhou Institute of Chemical Physics, engineering design experts from Fuyi International Engineering Company, as well as the project team members from Lanzhou Institute of Chemical Physics who were involved in the monitoring, testing, and analysis during the operation, stayed at the site throughout the night. Through close cooperation among all parties, the entire process was successfully streamlined, and the operating parameters of the equipment were continuously optimized to ensure stability; at 16:00 on the 11th, the concentration of polyoxymethylene in the reaction mixture began to rise ； At 7 a.m. on the 12th, the concentration of triomethylenetetraoxide reached 28.5%, and by 8 p.m. it had risen to 38% – **a level higher than that in the reaction solution using the sulfuric acid method. When the white crystalline pentaformaldehyde was presented before everyone, all those present were extremely excited. It represented a dream from four years ago, and today it has been successfully synthesized using ionic liquid catalysts for the first time on an international scale – a achievement that required great effort from the researchers, as well as the wisdom and hard work of people from various fields. 　　Trioxane is an important chemical product with a wide range of applications. The traditional synthesis method involves reacting concentrated formaldehyde in the presence of protonic acid catalysts such as sulfuric acid, but such catalysts are highly corrosive, require large capital investment for equipment, and cause environmental pollution. The successful commissioning of the pilot plant for the catalytic synthesis of paraformaldehyde using ionic liquids is of great significance: 1) This clean synthesis method for paraformaldehyde reduces environmental pollution and equipment corrosion compared to traditional methods that use dilute sulfuric acid as a catalyst, thereby significantly lowering investment costs ； 2) Triomethylenemethane is an important intermediate in the downstream development of methanol; it will lay the foundation for the advancement of new energy technologies based on methanol chemistry and open up new avenues for the development of coal chemical industry in China.
