摘　　要：以肉桂酸钠和环氧氯丙烷为原料,在不同的溶剂中合成了肉桂酸缩水甘油酯,考察了溶剂种类、溶剂用量、反应温度、反应时间和催化剂等对反应产率的影响,优化了反应条件.研究结果表明,溶剂的极性对反应结果影响显著,无催化剂条件下,以二甲基亚砜(DMSO)为溶剂,肉桂酸钠与环氧氯丙烷物质的量之比为1∶10,反应温度120℃,反应时间10 h,肉桂酸钠缩水甘油酯的产率可达81.5%.In this work,glycidyl cinnamate was synthesized by the reaction of sodium cinnamate with epichlorohydrin in different solvent.The effect of solvents,reaction temperature,reaction time and molar ratio of materials were investigated and the reaction conditions were optimized.The obtained results show that the polarity of the solvents has a significant effect on the yields.The isolated yield reaches up to81.5%with the sodium cinnamate and epichlorohydrin of1:10ratio at120℃for10h using strong polar dimethyl sulfoxide(DMSO)as a solvent.
