Title: METHOD FOR PRODUCING CARBAMIC ACID ESTER
Abstract:
Provided is an economically efficient method by which a carbamic acid ester is able to be produced with high yield and high selectivity. In a method for producing a carbamic acid ester according to the present invention, an amine, carbon dioxide and an alkoxysilane compound are reacted with each other in the presence of a catalyst containing a zinc compound or an alkali metal compound or in the presence of an ionic liquid. For example, a carbamic acid ester is produced by causing aniline, carbon dioxide and tetramethoxysilane to react each other at a temperature of from 150°C to 180°C in the presence of zinc acetate and 2, 2'-bipyridine.
