Abstract: In the presence of methanol, a new non-phosgene route for the preparation of methyl N-phenylcarbamate(MPC) was studied based on the reaction between aniline and methyl carbamate. The effects of reaction temperature, reaction time, catalyst content and the molar ratios of aniline to methyl carbamate and methanol on the reaction were studied, and the reaction mechanism over zinc chloride catalyst was proposed. Under the optimum reaction conditions, the MPC yield reached 89.90% and selectivity of MPC is 99.76%.

Key words: Aniline, Methyl carbamate, Methyl N-phenylcarbamate, Zinc chloride
