Document Type and Number:
Japanese Patent JPS62502117
Kind Code:
A
Abstract:
This invention relates to 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 ruthenium catalyst. The selectivity of this process is increased by the use of methanol instead of various other alkanols, e.g. ethanol. Preferably the catalyst is a halide-free ruthenium catalyst, e.g. a ruthenium carbonyl complex.
