【摘要】 以十六烷基三甲基氢氧化铵为催化剂和对苯二酚为阻聚剂，由甲基丙烯酸甲酯和乙二醇合成了甲基丙烯酸β-羟乙酯。通过正交实验获得了最佳反应条件：反应温度100～110℃，反应时间2．5h，酯醇摩尔比1：1．5，催化剂的用量为9．0mL。HEMA的产率为92．3％。更多还原

【Abstract】 β- Hydroxyethyl methacrylate (HEMA ) was synthesized by methyl methacrylate (MMA) and ethylene glycol with cethyl trimethylammonium hydroxide as catalyst and 1,4 - dihydroxybenzene as polymerization inhibitor. After orthognal trial, the optimum reaction conditions were obtained: reaction temperature 100~ 110℃, reaction time 2. 5 h, mole ratio of MMA: glycol 1: 1. 5, amount of catalyst 9. 0 mL, the yield of HEMA 92. 3%.更多还原
