Abstract:
A beta-alkoxy-omega-lactam is prepared by subjecting to heating in the liquid phase an omega-amino-beta-alkoxy-carboxylic acid ester. The heating may be carried out at a temperature of 150 DEG to 350 DEG C. If the amino compound is prepared by hydrogenation of the corresponding cyano compound, it is not necessary to separate the amino compound from the reaction mixture. The lactams obtained may be applied for preparation of polyamides and copolyamides.
