Production of methyl methacrylate via a two-step process using isobutylene
Thread Content
Help~~Are there any companies in China that use the isobutylene two-step process to produce methyl methacrylate? (Methacraldehyde one-step oxidation esterification to methyl methacrylate) If available, could some kind person provide a specific process flow? Diagrams would be even better:$
Shandong Yidali uses catalysts developed by the Chinese Academy of Sciences
The 50,000-ton plant jointly established by Yuhuang and Huayi has been put into operation; Huayi provides the technology, and the catalysts should also be from Huayi. Wanhua is building a facility with a capacity of 50,000 tons; it uses its own technology, and presumably its own catalysts as well
Huizhou Huiling Chemical Co., Ltd., a subsidiary of Mitsubishi Chemical, produces MMA using the isobutylene oxidation method
Could you provide more information?
This is for the college chemical engineering design competition; they don’t understand any of what was said upstairs.
Who is talking the most upstairs? :)
