摘　　要：对尿素与甲醇反应合成氨基甲酸甲酯(MC)这一绿色化学工艺进行了系统的研究,全面考察了反应温度、反应初始压力、反应时间及原料配比等因素对反应性能的影响.结果发现,该工艺过程合成氨基甲酸甲酯,尿素的转化率达85.1%,氨基甲酸甲酯的选择性为100%、得率为85.1%.The environment-friendly process of methyl carbamate(MC) from urea and methanol in an autoclave is systematically investigated. A better understanding of the effect of the reaction temperature, reaction time, ratio of the feeds and initial pressure and other appropriate reaction conditions on the reaction results has been obtained. Based on our study, the more suitable reaction conditions are available, and under such conditions the yield of MC is up to 85.1%, which is enhanced by 24.6% compared to the previous reports. Besides, the selectivity for MC reaches 100%. Therefore, we think the data we have obtained from our study may be useful to the further research on this novel process of MC.
