Abstract:A method of synthesis of acetylsalicylic acid by microwave irradiation with molecular sieve as catalyst was introduced,the effects of different reaction conditions on yield of the product were discussed,the experimental results showed that,the yield of acetylsalicylic acid reached 95.3% when molar ratio of salicylic acid to acetic acid anhydride was 1 ∶ 2.0,the molecular sieve catalyst amount was 5% of salicylic acid,the microwave power was 200 W and the reaction time was 2.5 min. |
Key words:microwave irradiation;molecular sieve;catalysis;synthesis;acetylsalicylic acid |
