| Abstract: | Diethyl Fumarate is synthesized by esterification of maleic anhydride and ethanol under microwave radiation on one-step method.The optimal conditions are as follows : power of microwave radiation 480W,amount of catalyst NaHSO4 used 3.6%,AlCl3 used 10%,molar ratio of alcohol to anhydride 3:1,microwave radiation time 15min.It is found out that,under the optimal conditions,the yield of the product reaches 92.5%. |
