| Abstract: | Methyl laruate was synthesized with p-methyl-benzenesulfonic acid as catalyst under microwave radiation. The influence factors of esterification reaction were investigated. The experimental results were shown that. molar ratio of methanol ： lauric acid ： catalyst was 20 ： 1 ： 0. 25, microwave power 195 W（30%）, microwave irradiation time 70 min, the yield of esterification reached 80%. The target compound was characterized by refractive index and IR. |
