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地研究 ,全面考察了反应温度、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中尿素的转化率达 75 1% ,MC的选择性 10 0 %。MC的得率比专利报道中的得率提高了 14 6 %。The environment-friendly process for preparing methyl carbomate (MC) from urea and methanol in an autoclave was systematically investigated. The effects of the reaction temperature, reaction time and ratio of feedstocks on the reaction were observed. Under optimum reaction conditions, i.e, reaction temperature of 160℃ and keeping 5 hour at this temperature, molar ratio of methanol to urea=5/1, the conversion of urea was up to 75.1% with a 100% selectivity of MC, and MC yield was 14.6% higher than that reported in the patent.
