近年来,随着涂料、粘合剂、化纤助剂以及电子工业的迅速发展,甲基丙烯酸烷基酯的需求量急剧增加,使用范围也日益扩大。甲基丙烯酸烷基酯的合成方法虽然不少,但较为实用者,至今仍限于酯化法与酯交换法两大类。由于甲基丙烯酸甲酯的价格远低于甲基丙烯酸,而且,自聚倾向也远小于后者,所以,酯交换法是一种更有吸引力的方 In recent years, with the rapid development of coatings, adhesives, chemical fiber additives and the electronics industry, the demand for alkyl methacrylates has dramatically increased and the range of applications has also been expanding. Although a lot of alkyl methacrylate synthesis, but more practical, is still limited to esterification and transesterification two broad categories. Since the price of methyl methacrylate is much lower than that of methacrylic acid, and the propensity to self-polymerization is much less than the latter, transesterification is a more attractive side
