摘　　要：以氧化铅为催化剂,考察了温度、时间、催化剂的量及原料配比等条件对合成苯氨基甲酸甲酯反应的影响,确定了适宜的反应条件,并试验了不同附载型固体催化剂,发现以三氧化二铝为载体效果最好。结果表明,附载型固体催化剂可使二苯脲的转化率达到94.7%,苯氨基甲酸甲酯收率可达98.2%。The synthesis of methyl N-phenyl carbamate （MPC） from diphenylurea and dimethyl carbanate （DMC）. Over the PbO catalyst , the effects of reaction temperature, reaction time, catalyst content and the molar ratios of diphenylurea to methyl carbanate were studied and ascertain the optimum reaction conditions . Different supports were tested to enhance the stability of the PbO catalyst and Al2O3 is found the best one . The MPC yield reached 94.7% and selectivity of MPC is 98.2 %.
