Abstract

Спосіб очищення ε-капролактаму включає гідрогенізацію суміші вода- ε -капролактам у присутності каталізатору гетерогенної гідрогенізації. Попередньо в суміші ε -капролактам - вода розчиняють газоподібний водень, після чого ця водень-вмісна суміш, що надійшла на гідрогенізацію, поглинає 90 - 100% водню, присутнього у процесі гідрогенізації.
