Abstract

The production of caprolactam by reacting 6-amino capronitrile with water in the presence of catalysts, using an initial mixture of 6-amino capronitrile and the tetrahydroazepine derivative of formula (I), and reaction in the liquid phase in the presence of heterogeneous catalysts, and a process for producing tetrahydroazepine derivative (I) and its use for making polycaprolactam.
