| Abstract: | Methyl α-naphthylacetate was synthesized by the esterification of α-naphthylacetic acid with methyl alcohol using Al_2(SO_4)_3·nH_2O as catalyst under microwave irradiation.The influences of amount of catalysts,microwave power,microwave irradiation time and the mole ratio of alcohol to acid were studied.The experimental results showed that the optimum reaction conditions were as follows: the amount of catalyst was 6%,microwave power,microwave irradiation time and the mole ratio of alcohol to acid were 600 W,28 min and 12∶1 respectively,the yield was 72.45%. |
