ABSTRACT:
A process for the production of urethanes is provided in which an organic primary or secondary amine is contacted, in the substantial absence of reactive oxygen, with a source of carbon monoxide and an organic compound containing at least one hydroxyl group in the presence of a catalyst comprising a member selected from the group consisting of carbonyls of Co, Mo, Ti, Rh, Fe, Ni and mixtures thereof. Urethane yields and selectivities are further improved by conducting the reaction in the additional presence of an organic compound containing at least one C.dbd.N or C.dbd.C group. When such unsaturated organic compounds are employed, the catalyst can additionally comprise iridium carbonyl.
