Abstract: Water and ammonia are removed from crude benzophenone-imines obtained by the catalytic reaction of ammonia with benzophenones of formula (I), in which R , R = (a) halogen, hydroxyl, nitro or amino groups, (b) 1-12C linear, branched or cyclic alkyl or alkoxy, optionally substituted with 6-10C aryl, F, Cl or Br, (c) 6-10C aryl or aryloxy, optionally substituted with 1-12C alkyl or alkoxy, (d) heteroalkyl groups comprising alkyl groups as above with in-chain O, S and/or N atom(s), or (e) heteroaryl groups with 5-10 ring atoms containing 1-3 O, S and/or N atoms; m, n = 0-5. The process comprises removing the ammonia by distillation and removing the water by distillation or with a drying agent.

Abstract: Cobalt catalysts (I) are claimed, in which the active material contains 55-98 wt% Co, 0.2-15 wt% P, 0.2-15 wt% Mn and 0.05-5 wt% alkali metal, calcd. as oxide. The calcined catalyst is reduced in a stream of hydrogen at final temps. of 200-400 degrees C and then surface-oxidised in a stream of air at final temps. of 20-60 degrees C. Also claimed is a process for the hydrogenation of organic nitriles and/or imines at 60-150 degrees C and 50-300 bar using (I) as catalyst.

Abstract: 2-Cyanoacrylic esters (I) of alpha , omega -bis(4-hydroxy-2,2,6,6-tetramethylpiperid-1-yl)alkanes or (cyclo)aliphatic polyols of the given formula (I) are new. R , R = the radical of an iso- or heterocyclic ring system with at least one iso- or heteroaromatic ring and ≥ 1 of R and R is not H, n = 2-10, if n = 2, X = a gp. of formula (II), m = 2-8; if n = 3-10, X = the radical of an n-hydric 3-20C (cyclo)aliphatic polyol, opt. with 1 or 2 heteroatoms in the cycloaliphatic gp. and up to 8 non-adjacent O or S atoms or -NH- or 1-4C alkylimino gps. in the aliphatic chain. Also claimed are various materials stabilised against the action of light, O2 and heat with (I).
