摘要
采用Benson基团贡献法,对碳酸二甲酯和醋酸苯酯合成碳酸二苯酯反应体系进行了反应焓变、反应熵变、吉布斯自由能变及平衡常数的计算。结果表明该反应体系较为复杂,为了提高碳酸二苯酯收率,需要深入研究反应工艺过程和开发高效新型催化剂。
The reaction heat, reaction entropy change, Gibbs free energy change and equilibrium constants of the reactions for the synthesis of diphenyl carbonate by transesteritlcation of dimethyl carbonate（DMC） and phenyl acetate（PA） were calculated by using Benson and Joback group contribution methods. The results show that the transesterification systems of DMC and PA are some complexities. To increase the yield of DPC, the reaction processes and high efficiency catalysts must be investigated.
