| Abstract: | The standard heat of formation, free energy and heat capacity of dimethyl carbonate(DMC) are calculated by the method of group contribution. A thermodynamic analysis of synthesis process of DMC by oxidation car-bonylation of methanol was carried out with the emphasis on calculations of equilibrium constants and conversions for the reaction. The optimum reation conditions for synthysis of DMC and the possibility to eliminate various side reactions were also investigated to provide the thermodynamic basis for the design of synthesis process of DMC and the development of catalysts thereof. |
