  • Process for the preparation of tertiaŕy amines from primary amines and nitriles
    Patent number: 6600075
    Abstract: Disclosed is a method for preparing tertiary amine compounds from primary amines and nitrites in the presence of hydrogen gas and a metal catalyst, or metal-containing catalyst composition, at a temperature from about 50° C. to about 200° C. and at a pressure from about 100 psig to 1500 psig. The primary amines and the nitriles used in the process may be diamines and/or dinitriles, or may be combinations of primary amines and/or nitrites. Also disclosed are novel tertiary amine compounds made by the described method.
    Type: Grant
