  • Patent number: 5530127
    Abstract: A process for the preparatiion of an amine which comprises reacting a primary or secondary alcohol and a nitrogen compound selected from the group consisting of ammonia and primary and secondary amines, at temperatures of from 80.degree. to 250.degree. C. and pressures of from 1 to 400 bar using hydrogen in the presence of a zirconium/copper/nickel catalyst, wherein the catalytically active material contains from 20 to 85 wt % of oxygen-containing zirconium compounds, calculated as ZrO.sub.2, from 1 to 30 wt % of oxygen-containing compounds of copper, calculated as CuO, from 30 to 70 wt % of oxygen-containing compounds of nickel, calculated as NiO, from 0.1 to 5 wt % of oxygen-containing compounds of molybdenum, calculated as MoO.sub.3 and from 0 to 10 wt % of oxygen-containing compounds of aluminum and/or manganese, calculated as Al.sub.2 O.sub.3 or MnO.sub.2, respectively.

  • Patent number: 5521139
    Abstract: Catalyst and process for the preparation of butene-2-diol-1,4 by the hydrogenation of butyne-2-diol-1,4 in aqueous solution over a palladium-containing fixed-bed catalyst, which is doped with lead or cadmium, in which a catalyst is used which has been made by applying Pd and Pb or Pd and Cd successively, by vapor deposition or sputtering, to a metal gauze or a metal foil acting as support material followed by forming the catalyst at an elevated temperature in air.
