四氯化锡可代替硫酸作为酯化催化剂.在五水四氯化锡催化下合成了肉桂酸甲酯,并用熔点、元素分析和红外光谱进行了表征.当肉桂酸、甲醇和四氯化锡的摩尔比为1∶7.5∶0.3,回流反应3 h,酯收率达89.2%.

Stannic chloride can be used as catalyst for esteri fi cation instead of sulphuric acid. Methyl cinnamate was synthesized in the prese nce of the catalyst of pentahydrate stannic chloride, and characterized by melt i ng point, elementary analysis and infrared spectrum. The yield of the ester co ul d reach 89.2% when the molar ratio of cinnamic acid,methyl alcohol and stanni c c hloride was 1∶7.5∶0.3,and the mixtur...
