Under the condition of microchannel reactor,using sodium methanol as catalyst,ethylene carbonate,methanol and ethanol as raw materials for transesterification reaction,the synthesis process of the main products of dimethyl carbonate,diethyl carbonate and methyl ethyl carbonate was studied.Finally,the reaction rule was as follows:when the residence time was 2 min,the reaction reached the equilibrium state,with the increase of material ratio,the product content increased.With the increase of catalyst content,the product content increased,but when the catalyst content increased to a certain value,DMC content decreased until the equilibrium.With the increase of temperature,DMC content increased,but the increase of temperature had little effect on the content of DEC and EMC.
