COMPOSITION AND PROPERTIES OF CAPROLACTAM OLIGOMERS OBTAINED FROM EXTRACTION WATER DIRECTED TO REGENERATION

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 “Kuibyshe-vAzot” allowed to recommend such compositions of reaction mixtures, directed to polymeri-zation, 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 en-vironmentally safe heat carrier that is superheated steam.

Key words: caprolactam, oligomers, polyamide-6, extraction water, regeneration, homogeniza-tion temperature, segregation temperature
