Patent

CA 2466442

Disclosed is a method for preparing tertiary amine compounds from primary amines and nitriles 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 nitriles. Also disclosed are novel tertiary amine compounds made by the described method.

L'invention concerne un procédé permettant de préparer des composés d'amines tertiaires à partir d'amines primaires et de nitriles en présence de gaz hydrogène, et un catalyseur métallique, ou une composition catalytique à teneur en métal, à une température comprise entre environ 50 ·C et environ 200 ·C et à une pression comprise entre environ 100 psig et 1500 psig. Les amines primaires et les nitriles utilisées dans ce procédé peuvent être des diamines et/ou des dinitriles, ou encore, elles peuvent être des combinaisons d'amines primaires et/ou de nitriles. En outre, l'invention concerne également des nouveaux composés d'amines tertiaires élaborés d'après le procédé susmentionné.
