摘　　要：由1,6-己二胺与碳酸二甲酯制备六亚甲基二氨基甲酸甲酯为一复合反应体系。本文用基团贡献法计算了该反应体系的反应热、吉布斯自由能变化、化学反应平衡常数。计算数据与文献值及试验结果比较,表明计算结果可靠,对实验室研究及工业化生产都有重要的指导意义。The synthesis of dimcthyl-hcxanc-1,6-dicarbamatc （HDU） from 1,6-Hcx ancdiaminc and dimcthyl carbonate is a complex reaction system. The reaction heat, change of gibbs free energy and equilibrium constant of the reactions are calculated by methods of group contribution. The comparison among the estimate data, literature data and experimental data shows that the results of estimation are reasonable, and very important for experimental research and scale up of the process.
