【摘要】 求文研究以杂多酸（ＨＰＡ）取代甲醇镁和阳离子交换树脂作为催化剂，采用酯交换的方法合成甲基丙烯酸十八酯，具有催化剂活性高反应速率快（提高１～５倍），产率高（９０％以上），且无需外加阻聚剂的特点，根据乙烯基单体的易聚合的特点，我们应用杂多酸（ＨＰＡ）作催化剂的同时还兼有阻聚剂的作用，开拓丙烯酸酯合成的新工艺。更多还原

【Abstract】 In this paper. replacing methoxide magnesium and canon exchange resin,heteropoly acid was used as catalyst for transesterification synthesize octadecyl methacrylate.It have high catalyzed activity, fast reaction rate. high yield(more than 90%). Character without adding Polymerization retarder. According to character of easy Polymerism of ethenyl monomer, we use HPA as polymerization retarder as well as catalyst. Exploit new sgnthcsizc technology of aerylate.更多还原
