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.
提供了一种生产尿烷的方法,其中在实质上没有活性氧的情况下,将有机一级或二级胺与一氧化碳源和至少含有一个羟基的有机化合物接触,在催化剂的存在下进行,该催化剂由钴、钼、钛、铑、铁、镍的羰基中的一种或混合物组成。通过在反应中进一步加入至少含有一个C≡N或C≡C基团的有机化合物,可以进一步提高尿烷的产率和选择性。当使用这样的不饱和有机化合物时,催化剂还可以另外包含铱羰基。
