The analysis results of the extraction water forming at various steps of the solutions concentration in a process of its regeneration at the production of PA-6 at JSC "KuibyshevAzot" allowed to recommend such compositions of reaction mixtures, directed to polymerization, the content in which of OL corresponds to their equilibrium values in a polymer and to reduce the temperature of carrying out of concentrating the extraction water using an environmentally safe heat carrier that is superheated steam.
