Synthesis of isoamyl salicylate catalyzed by sodium hydrogen sulfate

Haiying Huang

Abstract

With sodium hydrogen sulfate as catalyst, isoamyl salicylate was synthesized from salicylic acid and iso-pentanol.The optimized conditions are as following:the amount of catalyst is 0.8g per 0.1mol salicylic acid;the mole ratio of acid to alcohol is 1.8∶1;the reaction time is 2.5h and the temperature of oil bath is 145～155℃.The esterification rate of salicylic acid is about 97.81% under these conditions.
