| Abstract: | The synthesis of acetyl salicylic acid from salicylic acid and acetic anhydride was studied with microwave radiation and sodium hydrogen sulfate as catalyst. The influential factors upon the reaction were investigated. The experimental results showed that the appropriate conditions were: molar ratio of salicylic acid to acetic anhydride was 1∶2, weight of catalyst was 4% of the salicylic acid, microwave power was 464 W, the time of radiation was 60 s. The yield was about 89.5%. |
