Catalytic Synthesis of Amyl Cinnamate by Potassium Bisulfare

Amyl cinnamate was synthesized by the esterifiestion of amyl alcohol with cinnamic acid in the presence of potassium bisulfate monohydrate.The best reaction conditions were as follows:the amount of substance ratio of cinnamic acid/ amyl alcohol /potassium bisulfate is 1∶9.4∶0.46,the time of reaction were 4h and the ester yield reached 90.1%.The potassium bisulfate monohydrate is a catalyst with fairly high catalytic activity of the esterification reaction,which can accelerate amyl cinnamate synthesis.At the same time,the potassium bisulfate monohydrate can be recovered and reused.
