摘要
苯胺、CO2和甲醇合成苯氨基甲酸甲酯是一个绿色化学反应。采用基团贡献法估算了反应体系中部分组分的基础数据,在此基础上对该反应进行了系统的热力学分析。结果表明,在标准状态下,主反应为放热反应,不能自发进行。对各分步反应的热力学分析可知,以二苯基脲为中间产物的反应路径较易实现。
The synthesis of methyl N-phenyl carbamate from aniline, CO2 and methanol is a green chemical reaction. The basic data of some reaction components in this reaction system were calculated by the group contribution method, and then the reaction system was thermodynamically analyzed. The results show that the main-reaction is exothermic and can not proceed spontaneously. Among the step-reactions, the path via diphenyl urea intermediate is expected to proceed easily.
