Abstract
The methylated tertiary amines are selectively prepared by reacting a primary or secondary amine, or a nitrile or aminonitrile, including an aminoalcohol, etheramine, a polyamine or fatty polyamine or amidoamine, or amidopolyamine or dinitrile, with hexamethylenetetramine ("HMTA"), under hydrogen pressure at a temperature no greater than about 160.degree. C. and in the presence of a catalytically effective amount of a hydrogenation catalyst, e.g., nickel deposited onto appropriate support substrate therefor.
