Process for producing triomethylenetetrahydrofuran from formaldehyde
Thread Content
How many companies in China currently possess the technology for producing triomethylene from formaldehyde? Recently, the ion liquid method developed by Lanhua Research Institute has attracted a lot of attention. Could any experts provide some information on the previous triomethylenetetramine production technology? What are the similarities and differences between these two processes?
Lanhua Institute’s ionic liquids are still some way off from industrialization
It’s actually a very ancient type of strong acid resin; it has been given a new name: ion liquid. It has no industrial value!
Industrialization is challenging and there is still a long way to go; I hope they will succeed
I agree with the upstairs person’s assessment of ionic liquids. The only current use of ionic liquids is to generate hundreds of thousands of redundant papers each year, providing job opportunities for tens of thousands of researchers both domestically and internationally. Ionic liquids are not likely to be commercialized in the petrochemical industry in the foreseeable future. This is a general reference. It is by no means a strong-acid-type ionic liquid specifically designed for LICP.
Are the people upstairs all industry professionals? Who can introduce the existing triomethylenemethane processes?
I would like to ask how much money is required to invest in a triomethylenetetramine project these days? (Scale: 50,000 tons per year), thank you!
I also want to learn about the production processes for triomethylenetetraoxane. From what I’ve found, the current technologies available in China are not sufficient; I’m wondering what industrial-scale production methods exist?
Which company’s technology is better, DuPont’s or…? . . . . . .
It seems that the process developed by Lanhua Research Institute isn’t supported by everyone. Why? What is the current status of manufacturing processes at home and abroad?
ZAT Company in Poland and its counterparts in the United States are both present domestically; the trimellitic anhydride process used in Yuntianhua’s polyoxymethylene production relies on Polish technology
