摘要

Abstract

Methyl N-phenyl carbamate (MPC)

an important organic chemical

can be synthesized from aniline

and methanol. Catalyst Cu-Fe/ZrO

-SiO

was first prepared and its catalytic performance for MPC synthesis was evaluated. Then the influence of solvent on the reaction path of MPC synthesis was investigated. It is found that the reaction intermediate is different with acetonitrile or methanol as a solvent. With acetonitrile as a solvent

the synthesis of MPC follows the reaction path with diphenyl urea as the intermediate

while with methanol as a solvent the reaction occurs via the reaction path with dimethyl carbonate as the intermediate. The catalytic mechanism of cooperative catalysis comprising metal sites

Lewis acid sites and Lewis base sites is proposed according to different reaction intermediates.
