Abstract

A method for the preparation of alkali salts of lactams containing at least 4 carbon atoms in their rings, or mixtures of these compounds and a lactam, by reacting an alkaline hydroxide with an excess of melting lactam and eliminating the water formed during the reaction; This method is characterized in that, after the water formed during the reaction has been removed from the molten reaction mixture, the mixture is poured into a dry organic liquid inert to the lactams and the alkaline salts thereof and to a point of boiling above 30º C and a melting point below 15º C, after which the formed precipitate is filtered off.
