摘　　要：对环氧丙烷与二氧化碳合成碳酸丙烯酯的反应进行了热力学的计算、分析。采用的计算方法为多种估算法,考察了反应温度对热力学参数的影响。通过分析得出结论,该反应为放热反应,反应的吉布斯自由能?rG小于0,说明该反应体系在恒温恒压下有自发进行的可能性,即在热力学上讲是有利于反应的。In order to study the reaction of synthesizing propylene carbonate from carbon dioxide and propylene oxide, the thermodynamic of this reaction was calculated and analyzed by using multiple estimation method. Effect of the reaction temperature on thermodynamic parameters was investigated. The results show that that the reaction is exothermic, and its Gibbs free energy is less than O, which indicates that the reaction has the possibility of spontaneous reaction under constant temperature and constant pressure.
