ABSTRACT:
Urethanes are made by reacting an organic nitro compound with an organic compound containing at least one hydroxyl group in the presence of carbon monoxide, hydrogen and a catalyst system. The carbon monoxide and hydrogen are used in quantities such that the molar ratio of CO to H.sub.2 is from 0.3:1 to 3:1. The catalyst system is made up of at least one noble metal or compound of a noble metal from Group VIIIB of the Periodic System of Elements, at least one organic nitrogen base and a co-catalyst combination of iron or copper oxidic or hydroxidic compound and a chloride compound. The product urethanes are useful in the production of isocyanates and pesticides.
