ABSTRACT:
A process for preparing pure N-alkyl-lactams obtained by the reaction, in an organic solvent medium of, the corresponding lactamate of an alkali metal and an alkyl halide. This process consists of treating a reactive mixture of N-alkyl-lactam containing the corresponding cyclo-alkylene imine as an impurity with a current of carbon dioxide, until the cyclo-alkylene imine precipitates completely in the form of an insoluble carbonate, and then separating it from the precipitate.
