Abstract
It is found that p-toluene sulfonic acid is superior to sulfuric acid when used as catalyst for esterification of butyric acid with isoamyl alcohol. The optimized conditions in the synthesis of isoamyl butyrate catalyzed with p-topluene sulfonic acid are as follows: butyric acid is 0.2mole, molar ratio of isoamyl alcohol to butyric acid 1.5, cyclohexane 7.5ml, percentage of catalyst reaches 2.5% and the reaction time 2 hours. The yield of isoamyl butyrate could reaches 94.3%.
