摘　　要：在间歇反应釜中研究了尿素醇解合成氨基甲酸正丙酯的反应,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的影响。最佳反应条件被确定为:反应温度160℃,达到反应温度后反应时间为2.0h,反应初始充氮气压力1.0MPa,n(正丙醇)/n(尿素)为4/1。该条件下氨基甲酸正丙酯产率达到88.7%。The synthesis of 1-propyl carbomate from urea and 1-propanol in an autoclave was studied, and the effects of reaction temperature, reaction time, feed ratio of urea to 1-propanol and initial pressure on the reaction were investigated. The optimized reaction conditions were determined as follows： initial reaction pressure 1.0MPa, feed molar ratio of 1-propanol to urea 4： 1, reaction temperature 160℃ and keeping 2.0 hours under this temperature. The yield of 1-propyl carbomate was up to 88.7% under the optimized conditions.
