Abstract
Process for the manufacture of hexamethylenediamine by catalytic hydrogenation of adiponitrile in liquid phase, with pressures between 20 and 50 atmospheres and temperatures between 60 and 100º c, in the presence of a finely divided raney catalyst and caustic alkalis, characterized by introducing hydrogen and the adiponitrile as such in a liquid reaction medium consisting of hexamethylenediamine, water, a caustic alkali and a catalyst, while maintaining the caustic alkali content between 0.2 and 12 moles per kg of catalyst and the water content between 2 and 130 moles per mole of caustic alkali.
