Process for producing methyl methacrylate by the oxidation of isobutylene
Thread Content
The processes for producing methyl methacrylate via the oxidation of isobutylene include: 1. Three-step method: Isobutylene first reacts with air to be oxidized into MAL; MAL then reacts with air to be oxidized into MAA; and MAA is esterified with methanol to produce MMA. 2. Two-step method: Isobutylene reacts with air to be oxidized to form MAL, which is then esterified with methanol to produce MMA. 3. One-step method: Direct oxidation of isobutylene to produce MMA. Does anyone have the relevant process flow diagrams? If you have it, could you send it, study * study *? Or are there any channels through which I can find it? Could you give some suggestions? Thank you all!
The current mainstream approach is the two-step method, and this technology is primarily in the hands of certain manufacturers in Japan and the United States. In China, Shanghai Huayi and the Chinese Academy of Sciences possess relevant technologies; it is said that the project carried out by Shanghai Huayi in collaboration with Yuhuang produced qualified products by the end of 2017. There is no detailed information on the process flow.
The Jade Emperor has heard of it; it’s a very impressive company.
I’m writing a thesis, and I was wondering whether the two-step process using isobutylene for MMA production is currently the most promising approach in China. Thank you in advance
Bro, I’m working on my graduation project on this same topic this year. How about we exchange ideas?
