    Abstract: Disclosed is a method for producing pyrollidine of formula (I) by reacting 1.4-butandiol (BDO) of formula (II) with ammoniac in the presence of hydrogen and a supported, metal-containing catalyser, characterised in that, prior to its reduction with hydrogen, the catalytically active mass of the catalyser contains oxygen-containing compounds of aluminium, copper, nickel and cobalt and oxygen-containing compounds of tin in the wt.% range of 0.2 to 5.0%, calculated as SnO, and in that the reaction is performed in the liquid phase at an absolute pressure in the range of 160 to 220 bar, at a temperature in the range of 160 to 230
    o C, using ammoniac at a molar ratio to the used BDO of 5 to 50 and in the presence of 1.0 to 4.5 wt.% hydrogen relative to the quantity of BDO used.

    Abstract: The invention relates to a method for producing a mono-N-alkyl piperazine of formula (I), where R1 represents C1 - C5 alkyl or 2-(2-hydroxy-ethoxy) ethyl, by reacting diethanolamine (DEOA) of formula (II) with a primary amine of formula H
    2 N-R
    1 (III) in the presence of hydrogen and a catalyst moulded body. The reaction is carried out in the liquid phase at an absolute pressure ranging from 150 to 250 bar and the amination is carried out using a catalyst moulded body, the precursor of which can be produced according to a method in which (i) an oxidic material comprising copper oxide, aluminium oxide and lanthanum oxide is provided, (ii) powdered metallic copper and/or copper flakes and optionally graphite are added to the oxidic material, (iii) the mixture resulting from step (ii) is moulded into a moulded body. The oxidic material can be obtained by the simultaneous or successive precipitation of the components copper oxide, aluminium oxide and lanthanum oxide and by subsequent drying and calcination and the catalyst moulded body is calcined once again after the moulding process in step (iii).
