The present invention relates to a process for purifying caprolactam from solutions of cmde caprolactam by a direct treatment with one or more alkaline compounds of polyvalent metals, preferably bivalent and trivalent, without resorting to organic solvent extraction as used in the usual purification process. A further subject of the present invention is a facility devoid of a unit for organic solvent extraction and designed to carry out the caprolactam purification process described herein.

A method for separating a homogeneous catalyst from a solution includes forming a host-guest compound between a first isomer of the catalyst and inclusion compound in the solution and isolating the host-guest compound from the solution. The catalyst may be released from the inclusion compound by converting the first isomer of the catalyst to a second isomer of the catalyst.

A process for obtaining caprolactam from mixtures of caprolactam-containing polymers and polyurethane-containing polymers, in particular polyurethane block copolymers, by depolymerization, wherein the depolymerization of the mixture is performed in the presence of 0.05% to 5% by weight of a base at a temperature of 250? C. to 350? C. and a pressure of 5 to 700 mbar and wherein the caprolactam is obtained in gaseous form.
