Abstract
N-alkyl substituted amines are produced by reacting amine compounds, nitro compounds or nitroso compounds with an aldehyde or a ketone in the presence of hydrogen and a catalytic amount of a two component or a three component catalyst system, the former comprising a nickel catalyst and an acid, and the latter comprising a nickel catalyst, an acid and sulfur-containing compounds.
Claims6
A catalytic system comprising (a) a nickel catalyst, (b) at least one acid selected from the group consisting of sulfur-free acids and sulfur-containing acids in which the sulfur is in the form of a ##STR4## radical and (c) at least one sulfur-containing material selected from the group consisting of sulfur and a sulfur-containing compound at least a portion of said sulfur being in the form of at least one radical selected from the group consisting of -- S -- and ##STR5##
