A procedure for the separation of epsilon caprolocatama from 6-aminoformamide and oligomer from 6-aminoformamide.

摘要

The invention refers to a procedure for separating EP caprolocatama from 6-aminoacrylamide and oligomer from 6-aminoacrylamide, in which the oligomer of EP caprolocatama, 6-aminoacrylamide and 6-aminoacrylamide appears in the first water-based mixture, It comes into contact with an alcohol extraction solvent, resulting in the first stage of water refining which is poor in EP capr olactama, while an alcohol stage is an oligomer rich in kaprolone, containing 6-aminomethylamine and / or 6-aminomethylamine. This stage of alcohol contact with water (countercurrent wash water).The low alcohol extraction stage for the production of 6-aminoformamide and / or 6-hydroxyformamide, and the second aqueous phase of highly refined products of 6-aminoformamide and / or 6-aminoformamide.
