Abstract

L'invention concerne un procédé pour l'isomérisation des cyclohexane-bis(méthylamines) stéréo-isomères. On isomérise une cyclohexane-bis (méthylamine) par contact avec un composé organométallique à une température d'environ 100 degrés C à environ 200 degrés C. L'invention s'applique en particulier à un procédé d'isomérisation à température relativement basse et à la pression atmosphérique permettant d'obtenir rapidement des rendements élevés en produits isomérisés, en vue de leur utilisation pour la production de polyamides.
