| Abstract: | The standard heat of formation, free energy and heat capacity of ethylene carbonate (EC), diphenyl carbonate (DPC) and 2-phenoxy ethanol (POE) were calculated by the method of group contribution. A thermodynamic analysis of transesterification of EC and phenol was carried out with emphasis on calculation of equilibrium constants and conversions for the reaction. The results showed that direct synthesis of DPC with EC and phenol was not thermodynamically favorable. Thus, alternative approaches to production of DPC from EC and phenol were discussed here. |
