| Abstract: | This paper reports the synthesis of benzyl salicylate by phosphotungstic acid as catalyst. The results showed the op timized conditions were as follows： the mole ratio of acid to alcohol was 1 ： 1.8,the weight of catalyst is 1.4 g（ 0. 1 mol salicylic acid）, and the reaction time was 2 h,when the reaction temperature between 100 and 110℃, the yield was 78. 05%. |
