| Abstract In the present paper the comparison of the properties of many homogene ous and heterogeneous catalysts for DMC synthesis by ester exchange method has been made.The vapor-liquid equilibrium property for the binary system of MeOH-DMC has been given. The separation methods of the azeotrope formed by the above binary system have been described,the technological process for the DMC production by the ester exchange method has been desig ned,and the mass flows and raw material consumptions of the designed pro cess have been tabled. |
