  • Patent number: 6299778
    Abstract: The invention relates to a catalytically active, permeable composite material, a method for producing said composite material, and the use of the composite material. The inventive composite material can be used for separating mixtures of materials. The fact that various catalytically active substances can be incorporated into the material in various ways makes it highly flexible in terms of possible applications with properties which can be adapted to the particular purpose of an application. The inventive composite material can be used as a catalytically active membrane electrode, for example. According to the invention, the material is obtained by solidifying a suspension on and in a porous, permeable support. The production of the material requires either a very short period of heat treatment at temperatures of around 400° C. or treatment for a longer period at very mild temperatures of below 100° C.

  • Patent number: 6153576
    Abstract: Described are complexes of the transition metals manganese, iron, cobalt, ruthenium, molybdenum, titanium, vanadium and/or copper containing one or more ligands of general formula (I) ou (II)in which R is a direct bond or an optionally amin-group-substituted alkylene group with 1 to 4 C-atoms, A is a condensed or non-condensed ring system containing at least one nitrogen atom, B is hydrogen, an OH-group or the same as A, and X is a phenyl ring optionally substituted with and/or C.sub.1-4 alkyl or an optionally hydroxy-substituted C.sub.1-4 alkylene group. The complexes are suitable for use as activators or peroxy compounds in oxidative washing, cleaning and disinfectant solutions, washing and cleaning agents preferably containing 0.0025 to 0.25% by wt. of such activator complexes.
