Abstract: The invention concerns a method of simultaneously producing 6- aminocapronitrile (ACN) and hexamethylenediamine (HMD) by reacting adipodinitrile (ADN) with hydrogen in the presence of a catalyst containing nickel, at a temperature not below room temperature and at an elevated hydrogen partial pressure, optionally in the presence of a solvent. If the yield, based on the amount of ADN consumed, and/or the selectivity, based on the amount of ACN produced, drop(s) below a defined value, a) the reaction of ADN with hydrogen is interrupted by stopping the feed of ADN and, if present, also the solvent; b ) the catalyst is treated with hydrogen at a temperature in the range 150 to 400 .degree.C, using a hydrogen pressure of 0.1 to 30 MPa and a treatment time of 2 to 48 h; and c) the hydrogenation is subsequently continued using the catalyst treated in stage (b).
