| Abstract: | The paper reported a method of diethyl oxalate's synthesis: using ferric chloride as a catalyst,diethyl oxalate is synthesized from oxalic acid and ethanol by microwave radiation.The optimal conditions are as follows:molar ratio of alcohol to acid 4;mass ratio of catalyst 6%;power of microwave 400W;microwave time 12min.Under the optimal conditions,the yield of diethyl oxalate is high. |
