There is provided a process for preparing a carbamate compound, which is easy and commercially advantageous in that a carbamate compound can be produced with high yield from an amine compound and a carbonate compound. A process for preparing a carbamate compound which comprises the step of reacting an amine compound which has at least one amino group per molecule wherein the amine compound is selected from the group consisting of an aliphatic amine which may be substituted by an alicyclic group or an aromatic group or which may be interrupted by an alicyclic group or an aromatic group, and an alicyclic amine which may be substituted by an aliphatic group, with a carbonate compound in the presence of at least one organic solvent selected from the group consisting of a saturated cyclic hydrocarbon, an unsaturated cyclic hydrocarbon, and a non-cyclic ether by using a hydrolase.

A method of production of carbamic acid ester has a high yield and high selectivity and is superior in economy. The method of production of a carbamic acid ester includes reacting an amine, carbon dioxide, and an alkoxysilane compound in the presence of a catalyst containing a zinc compound or an alkali metal compound or in the presence of an ionic liquid. A carbamic acid ester is produced, for example by reacting aniline, carbon dioxide, and tetramethoxysilane at a temperature of 150 to 180° C. in the presence of zinc acetate and 2,2′-bipyridine.
