Abstract: Preparation of N-aryl-substituted 2-aminoalkyl-2-hydroxyalkylamines and N-aryl-substituted piperazines Ia and Ib (Ar = aryl; R = hydrogen, methyl, identical or different, R = hydrogen, alkyl> by reaction of an N,N-di(2-hydroxyalkyl)-N-arylamine II with ammonia or a primary amine III H2N-R III at elevated temperature and under elevated pressure in the presence of hydrogen and a catalyst by using for this reaction a supported catalyst whose active mass contains predominant amounts of copper and/or nickel and/or cobalt in metallic or oxidic form.

Abstract: Azo pigments of the beta -hydroxynaphthoic acid series containing an o-phenylenediamine and a trimellitic acid imide moiety. These pigments are best illustrated by the formula The pigments are suitable for example for coloring resins, surface coatings and printing inks and give brilliant hues of very good fastness properties.

Abstract: Preparation of alkanolamine with improved color properties comprises treating an alkanolamine with water using a heterogeneous hydration catalyst containing Ru, Re, Rh, Pd, Os, Ir, Pt and/or Ag and a support from active carbon, alpha Al2O3, ZrO2 and Ti oxide at high temperature, the cutting hardness being at least 10 N, the side pressure resistance being at least 30 N and the stamp hardness being at least 25 N when the support is active carbon.

Abstract: Azo pigments have the formula (I): where r is H, Cl or Br, ar' is arylene, Y has the formula -CONH- or -NHCO and Ar2 is substd. aryl which is free from COOH and sulphonamide gps. I can be used to colour spinning compsns, e.g. of viscose, in printing pastes for book or offset printing, in lacquers, contg. nitrocellulose, acrylates, melamine or alkyds, to colour phenoplasts and aminoplasts and thermoplasts such as polystyrene, polyalkenes or PVC, in gums or polysiloxane resins, in laminate papers and in textile printing. I have high resistance to light, weathering wind and migration.
