    • A process for the preparation of a hydrogenation catalyst by reduction of platinum in an oxidation stage of not less than 2 in an aqueous medium in the presence of a carboniferous support, optionally following partial poisoning with a sulfur, arsenic, tellurium, or antimony-containing compound, using a reducing agent, in which the reducing agent used is an ammonium or phosphonium salt of the general formula I �XR.sup.4 !.sub.n Y I in which X stands for N or P, R stands for hydrogen, C.sub.1 --C.sub.18 alkyl, C.sub.5 --C.sub.10 cycloalkyl, phenyl radical, and also a C.sub.1 --C.sub.4 alkyl radical substituted by phenyl, the phenyl radicals being mono-to tri-substituted by C.sub.1 --C.sub.6 alkyl, halogen, nitro or amino, if desired, provided that the radicals R may be the same or different but cannot simultaneously denote hydrogen, if X is P, n is an integer of 1 to 3, and Y is an organic anion which can reduce platinum in an oxidation stage other than zero to platinum in the oxidation stage of zero.
    • 一种通过在含水载体的存在下在水性介质中在不少于2的氧化阶段还原铂的氢化催化剂的方法,任选地在用硫,砷,碲或含锑的部分中毒后 化合物,使用还原剂,其中所用的还原剂是通式I [XR4] nYinin的铵盐或鏻盐,其中X代表N或P,R代表氢,C1-C18烷基,C5-C10环烷基 苯基,以及被苯基取代的C1-C4烷基,如果需要,苯基由C1-C6烷基,卤素,硝基或氨基单取代至三取代,条件是基团R可以相同 或不同,但不能同时表示氢,如果X为P,n为1至3的整数,Y为有机阴离子,在氧化阶段为零的情况下,铂可以在除氧以外的氧化阶段中还原为铂。

    • A hydrogenation catalyst is prepared by reduction of platinum in an oxidation state of not less than two using a reducing agent in an aqueous medium in the presence of a carbon-containing support after partial poisoning, where use is made of a compound of the general formula I ##STR1## where X, Y and Z can be identical or different and are hydrogen, C.sub.1 -C.sub.18 -alkyl, C.sub.5 -C.sub.10 -cycloalkyl, halogen, hydroxyl, C.sub.1 -C.sub.6 -alkoxy and --NR'R", where R, R' and R" can be identical or different and can be hydrogen, C.sub.1 -C.sub.18 -alkyl or C.sub.5 -C.sub.10 -cycloalkyl. Such a hydrogenation catalyst can be used for preparing hydroxylammonium salts and the process for preparing the above catalysts can also be used for regenerating hydrogenation catalysts based on platinum.
