Methyl N-phenyl carbamate (MPC) was synthesized from aniline, urea and methanol. The effects of catalysts, loading amounts, preparation condition of catalyst and reaction condition on the synthesis of MPC were investigated. It was shown that KNO3 modified zeolite HY gave the best performance to MPC formation among the evaluated catalysts, over which 93.1% aniline conversion and 82.6% MPC selectivity...
Methyl N-phenyl carbamate (MPC) was synthesized via a new non-phosgene route by reaction of phenylurea with methanol. The effects of catalysts, reaction temperature, reaction time and molar ratio of methanol to phenylurea were investigated. It was found that the catalyst played an important role in this reaction. Although MPC can be prepared in the absence of catalyst, 95.21% conversion of phenylurea...
