| Abstract: | The synthesis of acetylsalicylic acid from salicylic acid and acetic anhydride, using heteropoly acid of silicotungstic acid supported on activated carbon as catalyst was studied. The influences of catalyst quantities, ratios of reactants, reaction time and reaction temperature were investigated. The results showed that when the molar ratio of salicylic acid ：acetic anhydride = 1.0： 1.5, amount of catalyst was equal to 5.0 % of reacting acetylsalicylic acid,the reaction temperature was 71-75℃ and the reaction time was 15 min, the yield could reach 94.2%. |
