摘　　要：苯氨基甲酸甲酯是非光气法生产MD I的重要原料,碳酸二甲酯(DMC)与苯胺甲氧羰基化法是合成苯氨基甲酸甲酯最有前途的方法之一。文中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,所得结果可指导实验室研究及工业放大。Methyl N-phenyl carbamate is an important material for the synthesis of methylene diphenyl diisocyanate by non-phosgene route, and it is one of promising methods that methyl N-phenyl carbamate is synthesized from dimethyl carbonate（DMC） and aniline. The reaction heat, Gibbs free energy change and equilibrium constants of the reaction are calculated by the group contribution method, and the obtained results can guide the experimental research and scale-up of the process.
