摘要
用Benson基团贡献法计算了碳酸二甲酯(液态)、氨基甲酸甲酯(液态)和尿素(液态)的热力学数据ΔН0f、ΔG0f和热容ΔCp。对尿素和甲醇制备碳酸二甲酯的过程进行了热力学分析,计算了醇解反应的平衡常数,为尿素和甲醇制备碳酸二甲酯过程的设计和催化剂的研究提供了热力学依据。
The standard heat of formation, Gibbs free energy and heat capacity of dimethyl carbonate（1）, methyl carbamate（1） and urea（1） are calculated by the method of group contribution discovered by Benson S W. The chemical thermodynamics in the reaction prepared dimethyl carbonate from methanol and urea is studied and the equilibrim constant KO is evaluated according to the chemical thermodynamic principle. Thermodynamic data is provided for the research of process and catalyst in the preparation of dimethyl carbonate from methanol and urea.
