摘要
肉桂酸与乙醇在磷钨酸催化、微波辐射下反应得标题化合物 ,微波功率为 2 85W ,反应时间 2 0min ,转化率达到 95 %。探讨了各种因素对转化率的影响 ,选择出了最佳反应条件。
Ethyl phenylacrylate was synthesized by the reaction of cinnamic acid with alcohol in the presence of phosphotungstic acid under microwave irradiation.Microwave irradiation power was 285W and the reaction time was 20min,the conversion rate could reach 95%.Through experiment,the influencing factors of reaction were investigated.The optimum conditions were determined.
