摘 要:以铝箔作主催化剂、微量氯化汞和碘作助催化剂,取代的芳胺与碳酸二乙酯在130℃、常压下反应生成 N-芳基氨基甲酸乙酯。并对反应物与催化剂的配比、反应温度、时间作了详细的研究。N-苯基氨基甲酸乙酯的产率达85.2%。In this paper,a novel catalytic synthesis ofethyl N-phenylearbamates is reported.Aluminiumfoil was used as a catalyst and a promotercomprising of trace mercuric chloride and anequivalent weight of iodine was adopted.Thereaction of aniline with diethyl carbonate wasstudied carefully.The optimum reaction temper-ature,reaction time and the ratio of reactants toaluminium were selected.Under optimum condi-tions,ethyl N-phenyl carbamate was obtained in85.2% yield.Seven kinds of ethyl N-arylcarba-mates were prepared successfully from substituted-anilines.
