Abstract
A liquid phase catalytic alkylation of methylamine by long chain fatty alcohols, using as catalyst a mixture of compounds containing nickel, copper, and Group IIA metal, to provide mixtures of monoalkyl, dialkyl and trialkyl amines of preselected ratios, which, upon quaternization with methyl chloride, produce commercial mixtures of monoalkyl, dialkyl and trialkyl quaternary ammonium salts.
