ABSTRACT:
Secondary and tertiary amines are selectively prepared by a process comprising reacting an olefin, a nitrogen-containing compound and synthesis gas in the presence of a catalyst system comprising a ruthenium-containing compound mixed with a quaternary onium salt, optionally in the presence of a solvent, heating the resultant mixture to a temperature of at least 100.degree. C. and a pressure of at least 100 psi until there is substantial formation of the desired tertiary amine and separating the desired amine by a phase separation technique.
