Triformaldehyde is an important chemical raw material and is the best substitute for formaldehyde. Its solid-state products are relatively stable and have low toxicity and are easy to store and transport. At the same time, trioxymethylene is a monomer raw material for synthetic engineering plastics polyoxymethylene. POM can replace non-ferrous metals and alloy products such as copper, aluminum, zinc, etc., widely used in automobiles, machinery, chemicals, electronics, electrical appliances, instruments and daily necessities, etc. industry. At present, the synthesis technology of trioxymethylene is monopolized by European, American, and Japanese companies, and the sulfuric acid catalyst method is mainly used. The implementation of this project can obtain patents for synthetic technology of tripolyformaldehyde with proprietary intellectual property rights and unique proprietary engineering technologies. It can not only use methanol to develop economical new technologies for synthesis of trioxymethylene, but also investment, material consumption, cost, and product. Leading edge in quality and other aspects, providing basic raw materials for the development of polyacetal engineering plastics in China, thereby reducing dependence on foreign countries; and trioxane can be used as a substitute for formaldehyde in chemical and chemical industries, widening the application fields of formaldehyde and opening up new Methanol chemical industry provides a new way to use synthetic bulk chemicals.
On December 26th, China National Offshore Oil Corporation held a mid-term evaluation meeting for the "Tripolyformaldehyde synthesis technology" project in Beijing. The project is under the research and development of Lanzhou Institute of Chemical Physics under the Chinese Academy of Sciences. Fuyi International Engineering Company is responsible for the engineering design and China National Offshore Oil Corporation is responsible for the construction. The relevant leaders of the High Technology Bureau of the Chinese Academy of Sciences participated in the evaluation. Experts of the evaluation team and the leaders of the meeting carefully listened to the research report on the “new technology of ionic liquid catalytic synthesis of paraformaldehyde†made by the researcher Chen Jing of Lanhua Institute. After detailed discussions and careful review, they passed the research of New Technology based on Fuyi Company. The industrial base design of 3,600 tons/year scale carried out in-depth exchanges on relevant equipment and engineering related issues, fully affirmed and received the research results of the new synthetic technology of trioxymethylene in Lanhua Institute, and put forward a pilot test of trioxymethylene. Enlarged detailed implementation plan and schedule, starting equipment bidding in January 2007 and setting up a pilot plant in Hainan Dongfang Chemical Co., Ltd. in the third quarter of 2007, signifying that the new technology of ionic liquid catalytic synthesis of paraformaldehyde has officially entered industrial applications. Test phase.
