Abstract
L'invention concerne un procédé de séparation d'epsilon-caprolactame d'un mélange d'alimentation comprenant l'epsilon-caprolactame et un ou plusieurs isomères d'epsilon-caprolactame choisis dans le groupe comprenant 4-éthyl-2-pyrrolidinone, 5-méthyl-2-piperdinone, 3-éthyl-2-pyrrolidinone et 3-méthyl-2-piperdinone ou octahydrophénazine, lequel procédé consiste à mettre en contact, dans des conditions d'adsorption, ledit mélange avec un adsorbant, à adsorber sélectivement lesdits isomères d'epsilon-caprolactame ou l'octahydrophénazine jusqu'à exclusion sensible dudit epsilon-caprolactame, à séparer la partie non adsorbée du mélange d'alimentation et l'adsorbant et ensuite à récupérer un epsilon-caprolactame de grande pureté. Les isomères d'epsilon-caprolactame ou l'octahydrophénazine peuvent être récupérés par désorption dans des conditions de désorption. Le procédé peut être mis en application en mode par lots ou semi-lots ou de manière continue avec des technologies en lit mobile ou en lit mobile simulé.
