Abstract
Tertiary amines are prepared by reacting a long-chain olefin with carbon monoxide, hydrogen, and a primary or secondary amine in the presence of a catalyst composed of a rhodium- and/or ruthenium-containing compound using a specific solvent, followed by phase separation of the reaction product. This process facilitates recovery and re-use of the expensive catalysts.
