摘要
研究了用氨基磺酸作催化剂 ,在不同条件下合成水杨酸异戊酯。当n(异戊醇 )∶n(水杨酸 ) =1.0∶1.3,在 145～ 150℃下回流 4～ 5h ,产率可达 92 .0 %以上。
In this paper,we used aminosulfonic acid as catalyst and 4A molecular sieve as dehy-drater.Isoamyl salicylate was synthesized in different condition,isoamyl alcohol:salicylic acid was 1.0∶1.3(mole rate) at temperature about 145～150℃,the time about 4～5h,the productive rate reaches above 92.0%.
