| titleOfInvention | Process for the hydrogenation of nitrile functional groups to amine functional groups |
| abstract | The present invention relates to a process for the hydrogenation of nitrile functional groups to amine functional groups. It relates more particularly to a process for the complete or partial hydrogenation of dinitrile compounds to diamine or aminonitrile compounds. The invention relates to a process for the hydrogenation of nitrile functional groups to amine functional groups using hydrogen in the presence of a hydrogenation catalyst and of a strong inorganic base preferably deriving from an alkali metal or alkaline earth metal. According to the invention, the process comprises a stage of conditioning the catalyst which consists in mixing the hydrogenation catalyst, a predetermined amount of strong inorganic base and a solvent in which the strong inorganic base is not very soluble. This solvent is an amine compound, such as hexamethylenediamine in the case of the hydrogenation of adiponitrile to HMD and/or aminocapronitrile. |
