    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).

    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 promoter based on 2, 3, 4, or 5 elements selected from the group comprising aluminum, silicon, zirconium, titanium, and vanadium, and (C) 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 aliphatic alpha-omega dinitrile contains 1.0 ppm or more phosphorus. Catalysts are obtainable through the reductive and optional successive passivation of 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 invention relates to a method for producing phthalic anhydride by the gas phase oxidation of xylene, naphthalene or mixtures thereof in a multitube fixed-bed reactor, which is thermostatted by a heat-transfer medium, on two different fixed-bed catalysts arranged in layers. The invention method is carried out in such a manner that the maximum temperature in the second catalyst layer arranged in the direction of flow is approximately at least 52 DEG C lower than the maximum temperature in the first catalyst layer. The inventive method enables the production of phthalic anhydride with high yields under conditions relevant to practice.
