ENVIRONMENTALLY FRIENDLY PROCESS FOR THE HYDROGENATION OF DINITRILES

Process for converting a dinitrile to a diamine and optionally an aminonitrile, in which a Group VIII element catalyst is treated with a modifier either before or during a substantially solvent-free hydrogenation reaction in which the dinitrile is contacted with hydrogen in the presence of the catal...

Summary:Process for converting a dinitrile to a diamine and optionally an aminonitrile, in which a Group VIII element catalyst is treated with a modifier either before or during a substantially solvent-free hydrogenation reaction in which the dinitrile is contacted with hydrogen in the presence of the catalyst. La présente invention concerne un procédé de conversion d'un dinitrile en une diamine et éventuellement en un aminonitrile, dans lequel on traite un catalyseur d'un élément de groupe VIII avec un agent de modification soit avant ou pendant une réaction d'hydrogénation sensiblement exempte de solvant dans laquelle on met le dinitrile en contact avec de l'hydrogène en présence du catalyseur.
