Abstract
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 1-4 alkyl or an optionally hydroxy-substituted C 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. ##STR1##

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
161 words
A method of activating a peroxygen compound in an oxidizing, washing, cleaning or disinfecting solution, comprising the step of contacting said peroxygen compound with one or more complexes of one or more metals selected from the group consisting of manganese, iron, cobalt, ruthenium, molybdenum, titanium, vanadium, and copper containing a ligand of the formula I ##STR12## or formula II ##STR13## wherein each R independently is a bond, a C 1 to C 4 alkylene group, a C 1 to C 4 amino substituted alkylene group or a C 1 to C 4 alkylene group wherein one or more non-adjacent CH 2 units, which are not directly attached to the central N atom, are replaced by NH units, each A is the same or different and is 2-imidazolyl, 1-methyl-2-imidazolyl, or 2-benzimidazolyl, B is A or OH, and X is an optionally hydroxy- and/or C 1 to C 4 alkyl-substituted phenylene ring or an optionally hydroxysubstituted C 1 to C 4 alkylene group.
