Three phase hydrogenation of adiponitrile (ADN) to hexamethylene diamine (HMD) proceeds via aminocapronitrile (ACN). In a first step it has been investigated in selected conditions of temperature, pressure, reagent and catalyst concentrations, avoiding external and intraparticle transfer limitations
