甲基丙烯酸缩水甘油酯的正交设计合成
Synthesis of Glycidyl Methacrylate by Orthogonal Experiments
【摘要】 在季铵盐催化剂和对苯二酚阻聚剂存在下 ,由甲基丙烯酸甲酯和环氧氯丙烷合成了甲基丙烯酸缩水甘油酯 (GMA) .通过正交实验设计得到了最优反应条件 :反应温度 1 1 0℃ ,反应时间 4h ,催化剂四丁基溴化铵 (TBAB)的用量为 0 .8g.产率为 84.3 % ,纯度为98%
【Abstract】 Glycidyl methacrylate (GMA) was synthesized from methyl methacrylate (MMA) and epichlorhydrin in presence of quaternary ammohium salt as catalysts and 1,4 dihudroxy benzene as palymerization inhibitor. The optimum reaction conditions were obtained by orthogonal experimental design:reaction temperature 110 ℃, reaction time 4 h, ammount of TBAB catalyst 0.8 g. The yield is 84.3%, and the purity is 98%.
