| Abstract: | It was reported that the synthesis of cyclohexyl acetate catalyzed by p -toluenesulfonic acid supported on activated carbon under microwave irradiation. The experiment results showed that when powers of microwave irradiation was 400W, amount of catalyst was 1.2 g, molar ratio of alcohol to acid was 1.5:1, reaction time was 30 min , yield of the product was 96.0 %. In addition, it was found that under microwave irradiation, the reaction rate of esterification, yield of the product was higher than that of conventional heating method. |
