【摘要】 用肉桂酸与氯化苄在二甲基亚砜(DMSO)溶剂中直接反应制得肉桂酸苄酯。对反应条件进行了研究,实验结果表明:配料比为0.04∶0.064(摩尔比),溶剂DMSO用量为20mL,反应时间为3h,产率80.6%。还讨论了肉桂酸苄酯作为防晒剂的可行性。更多还原

【Abstract】 Benzyl cinnamate was synthesized through the reaction of cinnamic acid and benzyl chloride in DMSO. Various factors that affect the reaction are discussed. Optimum reaction conditions are as follows: mol ratio of cinnamic acid and benzyl chloride is 0.04∶0.064, DMSO solvent 20 ml, the reaction time 3 h, yield is 80.6%. It is also feasible that benzyl cinnamate can be used as ultra-violet absorpent.更多还原
