甲基丙烯酸甲酯的合成技术研究进展

Research progress in synthesis technologies of methyl methacrylate

概述了甲基丙烯酸甲酯(MMA)的合成方法,包括丙酮氰醇法、异丁烯法及乙烯法,并分析了各个合成方法的优缺点,丙酮氰醇法使用有毒原料HCN并会产生大量废料,不符合绿色生产要求,将会面临逐步淘汰,异丁烯法及乙烯法生产过程绿色清洁,符合我国国情及战略需求,是未来的主要发展方向。此外,也对用于异丁烯法生产MMA的钯系催化剂及金系催化剂进行了分析。

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.
