    Abstract: The invention relates to a method for the catalytic hydrogenation of adipodinitrile to hexamethylene diamine at a high temperature and at high pressure in the presence of catalysts based on elementary iron as the catalytic component, and ammonia as a solvent. The method is characterised in that a) adipodinitrile is hydrogenated at temperatures of 70 to 220 DEG C and at pressures of 100 to 400 bar in the presence of catalysts based on elementary iron as the catalytic component, and ammonia as a solvent to produce a mixture containing adipodinitrile, 6-aminocapronitrile, hexamethylene diamine and high boilers, until the sum of the 6-aminocapronitrile and adipodinitrile concentration is 1 to 50 wt. % in relation to the ammonia-free hydrogenation mixture; b) ammonia is separated out of the hydrogenation discharge; c) hexamethylene diamine is separated out of the remaining mixture; d) 6-aminocapronitrile and adipodinitrile are separated from the high boilers together or separately and e) 6-aminocapronitrile, adipodinitrile or their mixtures are returned to step a).

    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: A process for reducing the level of an aliphatic monounsaturated amine (IV) in a mixture (V) containing an aminonitrile (I) or a diamine (II) or a dinitrile (III) or mixtures thereof as well as said mine (IV) by a) reacting said mixture (V) with an anionic nucleophile (VI) which contains a nucleophilic atom selected from the group consisting of oxygen, nitrogen and sulfur, which is capable of taking up an H + ion to form an acid having a pK a value in the range from 7 to 11, as measured in water at 25° C., and which has a relative nucleophilicity, as measured in methyl perchlorate/methanol at 25° C., in the range from 3.4 to 4.7 when said nucleophilic atom is oxygen, in the range from 4.5 to 5.8 when said nucleophilic atom is nitrogen, and in the range from 5.5 to 6.8 when said nucleophilic atom is sulfur, in an amount in the range from 0.01 to 10 mol per mole of said amine (IV) in said mixture (V) at a temperature in the range from 50 to 200° C. to obtain a mixture (VII), b) distilling said aminonitrile (I) or said diamine (II) or said dinitrile (III) or mixtures thereof from said mixture (VII) at a temperature in the range from 50 to 200° C. and at a pressure in the range from 0.1 to 100 kPa to obtain a bottom product (VIII), which comprises c) distilling an aminonitrile (I) or diamine (II) or dinitrile (III) or mixtures thereof from said bottom product (VIII) at a temperature which is lower than that chosen in step b).

    Abstract: The invention relates to a process for the selective hydrogenation of alkynes and dienes in C2-C5+-olefin mixtures,-in C2- or C3-streams of the olefin preparation by cracking. The method comprises conducting the hydrogenation in the presence of a catalyst particle comprising (a) a metal of the tenth group of the Periodic Table, (b) a metal of the eleventh group of the Periodic Table and (c) optionally a compound of a metal of the first or second group of the Periodic Table. Components (a) and (b), and optionally (c), are applied to a support selected from the group consisting of silica, titanium dioxide, zirconium oxides, spinels, zinc aluminates, zinc titanate, aluminosilicates and mixtures thereof. The metal of the eleventh group is distributed homogeneously over the cross-section of the catalyst particle, and the metal of the tenth group is present in an edge layer close to the surface of the catalyst particle.
