摘　　要：以钨硅酸为催化剂,通过桂酸和戊醇酯化反应合成桂酸戊酯,研究了各有关因素对产品酯化率的影响。实验证明,钨硅酸是合成桂酸戊酯的良好催化剂,在酸醇物质的量比为1∶2.5,催化剂用量为1g/0.05mol桂酸,带水剂苯为7mL,反应时间为1.5h条件下,桂酸戊酯的酯化率可达99.2%。Amyl cinnamate was synthesized from cinnamic acid and amyl alcohol using tungstosilicic acid as catalyst.The influence factors such as molar ratio of cinnamic acid to amyl alcohol,amount of catalyst,and reaction time on the yield of amyl cinnamate were discussed.
