    Abstract: A method for the separation of C14 to C30 secondary alkyl primary amines from crude mixtures containing, in addition to the amine, paraffins, ketones, alcohols and polyfunctionals wherein the crude mixture is initially treated with an acid, water and low molecular weight alcohol thereby forming an aqueous amine salt layer, separating the low molecular weight alcohol from the aqueous layer, treating the aqueous layer with a base and separating the amines from the aqueous layer.
