The Lanzhou Institute of Chemical Physics' technology for synthesizing paraformaldehyde was successfully industrialized for the first time. The industrial test of the technology for synthesizing paraformaldehyde using an ionic liquid catalyst, transformed from the independent intellectual property rights of the Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences, has recently been successful for the first time in the world. It will lay the foundation for the development of new methanol chemical energy technologies and expand new avenues for the development of my country's coal chemical industry. Triformaldehyde is an important intermediate raw material for the downstream development of methanol and has a wide range of uses. Traditional synthesis methods are highly corrosive, require large investment in equipment, and pollute the environment. The ionic liquid catalyst synthesis of paraformaldehyde technology successfully developed by scientific researchers in our province is a clean synthesis technology that can reduce environmental pollution and equipment corrosion, and greatly reduce investment. The technology completed laboratory verification in 2006 and achieved industrial testing after several years of efforts. For this project, the Lanzhou Institute of Chemical Physics is responsible for the relevant core technologies, Fuyi International Engineering Company is responsible for the pilot design, and China National Blue Chemical Corporation is responsible for the construction and commissioning of the pilot plant. Qualified paraformaldehyde is produced at China National Blue Paper Petrochemical Co., Ltd. (Hainan Dongfang).
Yes, it has opened up a channel for methanol and other products. I hope it can be put on the market as soon as possible.
What are the main industrial and domestic uses of parformaldehyde?
Ionic liquid catalysts have been popular for a while. They are probably very expensive. Are they affordable for industrial use?
Can this technology now be applied to large industrial installations?
Paraformaldehyde is the main intermediate for the production of engineering plastics, and can be used in both homopolymerization and copolymerization.
It should be possible, but the amplification problem needs to be solved.
Ionic liquids are relatively expensive in terms of unit price, but they can be recycled and the loss is small. Lower operating costs than traditional catalysts.
The technology of synthesizing paraformaldehyde using ionic liquid catalysts only differs in the synthesis process. Does the subsequent process need to undergo extraction to separate light boilers and heavy boilers in order to achieve a purity of more than 99%? There should be no need for a concentration unit.
It is hoped that industrialization can be accelerated and the traditional sulfuric acid method can be replaced, which will not only save a lot of steam but also reduce environmental pollution.
The project completed laboratory verification in 2006, device design in 2007, and completion in October 2008. On the day of the test run, specially invited expert Mr. Zhang Xinzhi, deputy directors of the Lanzhou Institute of Chemical Physics, Researcher Xia Chungu and Researcher Chen Jing, engineering design experts from Fuyi International Engineering Company, and project team members from the Lanzhou Institute of Chemical Physics who participated in the drive-up tracking detection analysis were stationed at the site all night. After close cooperation between all parties, the entire process was successfully opened up and the operating parameters of the device were continuously optimized and stabilized. At 16:00 on the 11th, the concentration of paraformaldehyde in the reaction solution began to rise. ； The concentration of paraformaldehyde reached 28.5% at 7:00 on the 12th and 38% at 22:00. * * Higher than the concentration of parformaldehyde in the reaction solution of the sulfuric acid method.
