    Abstract: The invention concerns a method of simultaneously producing 6aminocapronitrile (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 ~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).

    Abstract: The invention relates to a method for producing aliphatic alpha, omega-amino nitriles in the presence of a catalyst composed of (a) iron or an iron based compound or a mixture thereof, (b) 0.01 to 5 wt. % in relation to (a) a promotor based on 2, 3, 4, or 5 elements selected from the group comprising aluminum, silicium, zirconium, titanium and vanadium and (c) 0 to 0.5 wt. % in relation to (a) a compound based on an alkaline metal or alkaline-earth metal. The inventive method is characterized in that the applied aliphatic alpha, omega-amino dinitrile contains 1.0 wt. ppm or more phosphor. Catalysts are obtainable through the reduction and optional successive passivation of a magnetite, whereby the catalysts have a BET surface of 3 to 10 m2/g, a total pore volume of 0.05 to 0.2 ml/g, an average pore diameter of 0.03 to 0.1 mm and a pore volume portion in the range of 0.01 to 0.1 mm of 50 to 70 %.

    Abstract: The present invention relates to a process for preparing compounds containing NHi2 groups by hydrogenating compounds having at least one unsaturated carbon-nitrogen bond with hydrogen in the presence of a catalyst at temperatures being higher thane room temperature and an elevated hydrogen partial pressure in the presence or absence of a solvent, which preparation process comprises (a) using a catalyst comprising a cobalt- and/or iron catalyst, (b) interrupting the hydrogenation when the hydrogenated compound transformation degree and/or selectivity of the required product drops below a defined limit or when the amount of undesired byproducts increases above a defined limit by stopping the feed of the compound to be hydrogenated, (c) treating the catalyst at a temperature ranging from 150 to 400 degC with hydrogen using a hydrogen pressure within the range from 0.1 to 30 MPa and a treatment time within the range from 2 to 48 hours, and (d) subsequently continuing the hydrogenation of the compound having at least one unsaturated carbon-nitrogen bond as well as the regeneration of cobalt- and/or iron-containing catalysts.
