Patent

CA 2280826

The invention relates to a method for hydrogenating a compound from the group of imines or enamines (I) to an amine (II) in the presence of a nitrile (III), whereby said nitrile (III) is essentially not hydrogenated. The method is characterized in that a mixture containing a compound (I) and a nitrile (III) is reacted in the presence of a catalyst (IV) with a gas containing molecular hydrogen.

L'invention concerne un procédé d'hydrogénation d'un composé du groupe des imines ou des énamines pour former une amine II en présence d'un nitrile III, ledit nitrile III n'étant sensiblement pas hydrogéné. Ce procédé se caractérise en ce qu'un mélange contenant un composé I et un nitrile III est mis à réagir en présence d'un catalyseur IV avec un gaz contenant de l'hydrogène moléculaire.
