Patent

CA 2396025

The invention relates to a method for purifying lactames, especially lactames obtained by cyclization hydrolysis of an aminoalkylnitrile, and more particularly, to the purification of .epsilon.-caprolactame obtained by cyclization hydrolysis of the aminocapronitrile. This crystallisation process can either be carried out directly on the cyclization reaction medium after removal of the volatile components or on a medium that has been subjected to different treatments or on a caprolactame extracted from the reaction medium, for example by distillation.

L'invention concerne un proc~d~ de purification de lactames, notamment les lactames obtenus par hydrolyse cyclisante d'un aminoalkylnitrile.Elle se rapporte plus particuli~rement ~ la purification de l'-caprolactame obtenu par hydrolyse cyclisante de l'aminocapronitrile. Cette cristallisation peut Útre r~alis~e soit directement sur le milieu r~actionnel de cyclisation apr~s ~limination des compos~s volatils soit sur un milieu ayant subi diff~rents traitements ou sur un caprolactame extrait du milieu r~actionnel, par exemple par distillation.
