| Abstract: | Isopropyl salicylicate was synthesized using salicylic acid and i-propanol as raw materials and p-toluene sulphonic acid supported on granule activated carbon as the catalyst. The influencing factors of the reaction were investigated. Experimental results indicated that isopropyl salicylicate yield of 94.45% was attained under the optimum condition of esterification reaction as follows ： n （ salicylic acid） ： n （ isopropanol） = 1： 3.0, reaction time of 3.0 h, catalyst dosage 4.6% of total mass of the reactants, water carrying agent 8 mL. |
