A process is provided for the hemihydrogenation of dinitriles to corresponding aminonitriles using hydrogen in the presence of a supported catalyst. The supported catalyst comprises ruthenium supported on a carbon black, called acetylene black, resulting from the pyrolysis of paraffin oils.

Un proceso se proporciona para el hemihydrogenation de dinitriles a los aminonitriles correspondientes usando el hidrógeno en la presencia de un catalizador apoyado. El catalizador apoyado abarca el rutenio apoyado en un negro de carbón, llamado negro de acetileno, resultando de la pirolisis de los aceites de parafina.
