Abstract
Process of hydrogenation of adiponitrile or e-aminocapronitrile at high pressure in liquid phase by means of hydrogen in the presence of a raneyen catalyst, which at least part of the amount of compound to be hydrogenated is added to raney catalyst which has already been used in a hydrogenation or hydrogenation phase and is still in suspension in the liquid product of said previous hydrogenation or previous phase of hydrogenation and is under a partial pressure of hydrogen of at least one atmosphere.
