Progress of Catalysts for Isobutylene to Methacrolein

Selective oxidation of isobutylene to methacrolein is a key step in the production of methyl methacrylate from isobutylene.The progress of catalysts,which include composite-oxides catalysts and heteropoly compounds catalysts,for selective oxidation of isobutylene to methacrolein were summarized,the mechanism of this reaction on Mo-Bi catalysts was discussed.
