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 halide-free ruthenium catalyst is disclosed. In the process of this invention, the rate of conversion and selectivity to urethane is increased by providing a primary amine in the reaction solution.
