| Abstract: | The Moore Gibbs free energy change of diphenyl carbonate（DPC） synthesis from phenol and carbon dioxide is calculated according to the principles of classical thermodynamics.It is shown that the higher temperature is more favorable than the lower temperature,and the yield of DPC is raised by increasing the pressure of carbon dioxide.The experimental data are consistent with the calculation result,but the actual yield of DPC is lower than the calculated value. |
