    Abstract: Preparation of amines from alcohols, nitrogen compounds and hydrogen is effected over a catalyst containing oxygenated compounds of zirconium, copper, nickel and optionally aluminium and/or manganese. Preparation of amines involves reacting primary or secondary alcohols, nitrogen compounds selected from ammonia and primary or secondary amines, with hydrogen at 80-250 degrees C and 0.1-40 MPa over a catalyst at least containing zirconium, copper and nickel. Specifically, the catalytically active mass contains metal oxides of Zr (20-85 wt. %, as ZrO2), Cu (1-30 wt.%, as CuO), Ni (14-70 wt.%, as NiO) and optionally aluminium and/or magnesium (0-10 wt.%, as Al2O3 and/or MnO2). The molar ratio of Ni / Cu is ≥ 1, and the catalyst is free of cobalt or molybdenum oxides. An Independent claim is also included for a catalyst formed.

    Abstract: Catalysts (I) are claimed containing, on a porous metal oxide support, more than 6-50 wt% cobalt, nickel or a mixture thereof, 0.001-25 wt% ruthenium, 0-10 wt% copper and 0-5 wt% promoter(s) selected from iron, rhodium, palladium, platinum, iridium, osmium, silver, gold, chromium, molybdenum, tungsten, rhenium zinc, cadmium, lead, manganese, tin, lithium, sodium, potassium, rubidium, caesium, phosphorus, arsenic, antimony, bismuth, tellurium and thallium. (I) are obtained by (a) impregnating the support with the metals and promoters or their compounds but using only halogen-free compounds, (b) drying and calcining, and (c) reducing the calcined catalyst in a stream of hydrogen. Also claimed is (i) the process as described above for the production of (I), and (ii) a process for the production of amination products by reacting alkylene oxides, alcohols, aldehydes or ketones with ammonia or prim. or sec. amines in presence of free hydrogen and catalyst (I).

    Abstract: The invention concerns a process for simultaneously preparing 6-aminocapronitrile and hexamethylene diamine proceeding from adipodinitrile. The process is characterized in that: (1) adipodinitrile is partially hydrogenated in the presence of a catalyst in order to obtain a mixture containing 6-aminocapronitrile, hexamethylene diamine and adipodinitrile; (2) 6-aminocapronitrile and hexamethylene diamine are separated from the mixture; (3) between 0.01 and 10 wt %, relative to adipodinitrile, of an acid or an acidic ion exchanger is added to the part substantially containing adipodinitrile, and the adipodinitrile is separated from the mixture; and (4) the adipodinitrile is returned to step (1).
