| Abstract: | Cinnamic acid were synthesized by the Perkin reaction between benzaldehyde and acetic anhydride under the catalysis of potassium carbonate,and the yield can reach 93%.The unreacted benzaldehyde was removed in experimental process by the extraction method instead of steam distillation method,and the process was simplified,the reaction time was shortened,meanwhile the infrared spectrum of products was analyzed. |
