PROCESS FOR THE PREPARATION OF URETHANES |
摘要 |
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. |
