Abstract:

The synthesis methods of methyl methacrylate (MMA) were summarized, including acetone cyanohydrin, isobutylene, and ethylene methods, and their advantages and disadvantages were analyzed. A toxic raw material, HCN, was used in the acetone cyanohydrin method, generating a lot of waste. This does not meet the requirements of green production and therefore faces to be eliminated gradually. The production process of isobutylene and ethylene is green and clean in accord with the national conditions and strategic requirement of China. This has been considered as a main development direction in the future. In addition, the palladium?based catalysts and gold?based catalysts used in the production of MMA by the isobutylene method were also analyzed.

Key words: methyl methacrylate, acetone cyanohydrin method, isobutylene method, ethylene method
