甲基丙烯醛一步法制甲基丙烯酸甲酯催化剂研究进展

介绍了目前生产甲基丙烯酸甲酯(MMA)的几种工业化合成路线,其中甲基丙烯醛直接氧化酯化法因其环境友好而得到更多的关注。列举了甲基丙烯醛一步法制备MMA的几类催化剂,包括其制备方法、催化性能、使用条件等,指出钯系催化剂的研制将成为今后的主要发展方向,在改进催化剂性能的同时更应加强基础理论方面的研究。

Research progress in catalysts for manufacture of methyl methacrylate by one-step conversion of methacrolein

The recent commercialized processes for the production of methyl methacrylate(MMA) are described,the direct oxidative esterification of methacrolein has got more attention for it was an environmentally benign process.The catalysts used for manufacture of MMA by one-step conversion of methacrolein were studied,including their preparation methods,catalytic activities and reaction conditions.On the basis of the comparisons among different catalysts,it is pointed out that Pd catalyst is the developing tendency,and more basic theoretical research should be strenthened while the catalytic effects being improved.
