Heterogeneous catalytic method for preparing phenyl carbamate

The invention relates to a heterogeneous catalytic method for preparing phenyl carbamate, which comprises the following steps: using aniline as well as carbamate, a heterogeneous catalyst and a solvent the molar ratios of which are respectively 1: (1.5-20), ( 20-60): 1,1: (1-15), and adding into an autoclave; after replacing the gas in the autoclave with an inert gas, carrying out reaction under a stirring state; and filtering a reaction liquid under the condition of vacuum so as to separate the catalyst and the reaction liquid, and then carrying out vacuum distillation for the reaction liquid to remove the solvent and unreacted carbamate. The catalyst is an organic lead Pb (CmHnOx) y catalyst or an organic zinc (Zn (CmHnOx) y catalyst, wherein m = 1-8, n = 4-18, x = 1-3, and y = 0.5-4. The invention is easy to operate, and the used catalyst has the advantages of high catalytic activity, good selectivity and stability, easy separation regeneration, strong practicality and the like.
