| Abstract: |
| 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. |
