Abstract: The invention relates to a process for preparing an ethylene amine mixture, which comprises hydrogenating an amino nitrile mixture comprising at least 30% by weight of aminoacetonitrile (AAN) and at least 5% by weight of iminodiacetonitrile (IDAN) in the presence of a catalyst. Ethylenediamine (EDA) and/or diethylenetriamine (DETA) and, if appropriate, further ethylene amines can be isolated from the ethylene amine mixtures obtained.

Abstract: The present invention relates to a method for cleaning waste water by bringing the waste water to be cleaned in contact with a strand-shaped TiO2 photocatalyst, which has a BET surface of 25 to 200 m2/g, a pore volume of 0.10 to 1.00 m L/g, and a mean pore diameter of 0.005 to 0.050 µm, while being irradiated with light. The invention further relates to the use of said strand shaped TiO2 photocatalyst, which has a BET surface of 25 to 200 m2/g, a pore volume of 0.10 to 1.00 m L/g, and a mean pore diameter of 0.005 to 0.050 µm for cleaning waste water, while being irradiated with light.

Abstract: Method for manufacturing amines of formula I, by converting a carbonyl compound of formula II with an amine of formula III, where R1 and R2 are different to one another and in each case stand for an organic radical having 1 to 20 C atoms, which can also contain heteroatoms if required, R3 stands for a C1-C6-alkyl group and R4 stands for an aryl group which can be partially or fully halogenated, and/or can carry one to three radicals from the group containing cyano, nitro, C1-C6-alkyl, C1-C6-halogenalkyl, hydroxy, C1-C 6-hydroxyalkyl, C1-C6-alkoxy, C1-C6-halogenalkoxy, hydroxycarbonyl, C1-C6-alkoxycarbonyl, C1-C6-alkylamino, di(C1-C 6-alkyl)amino, aryl and aryl(C1-C6-alkyl); and stand for the S or R configuration, and stand for the S and/or R configuration; characterized in that the conversion is conducted in the presence of a heterogeneous imination catalyst, a hydrogenation catalyst and hydrogen.
