| Abstract: | Benzyl p-hydroxybenzoate was directly synthesized from p-hydroxybenzoic acid and benzyl alcohol using sodium bisulfate(A) or zirconium sulfate(B) as catalysts under microwave irradiation.The optimal reaction conditions were found as follows: microwave power 464 W,irradiation time 4 min,the molar ratio of alcohol to acid 5∶1.Under the optimal conditions,with 0.2 g sodium bisulfate or zirconium sulfate as catalysts,the yield was up to 98.6% and 97.5%,respectively.The experimental results showed that proper microwave irradiation could speed up the reaction of the esterification and high yield could be obtained. |
