Description

ABSTRACT:
A process for preparing urethanes by reacting a solution of a nitrogen-containing organic compound and a hydroxyl-containing organic compound with carbon monoxide in the presence of a catalyst comprising rhodium, as a metal or compound, is disclosed. In the process of this invention, the rate of conversion and selectivity to urethane is increased by providing a rhodium catalyst comprising a polyamino ligand having at least two tertiary amino groups capable of coordinating with rhodium.
