| Abstract: | Coumarin was synthesized by Perkin reaction in the presence of potassium fluorine as a catalyst. By the method ,yield of coumarin was improved greatly, the reaction temperature was lowered, and the reaction time was also decreased. The best molar rate of the reaction was potassium fluorine:salicylaldedyde:acetic anhydride=1.8:1.0:3.2. |
