| Abstract: | Acetylsalicylic acid was synthesized from salicylic acid and acetic anhydride using aminosulfonic acid as the catalyst, and the effects of reaction condition were investigated. The experimental results indicated that the optimum condition was as follows: n(salicylic acid)∶ n(acetic anhydride)∶n(aminosulfonic acid)=1∶ 1.5∶0.006 1, reaction for 25 min, reaction temperature (81-85) ℃. Acetylsalicylic acid yield of 93.34% was obtained. |
