Japanese Patent JPH0765074

Kind Code:

B2

Abstract:

Novel bleach and oxidation catalysts, a method of bleaching substrates using these catalysts and bleaching (detergent) compositions containing the catalysts are reported. The catalysts are a manganese-based co-ordination complex of the general formula : [LnMnmXp] Yq wherein Mn is manganese in the IV-oxidation state; n and m are independent integers from 2-8; X represents a co-ordination or bridging species; p is an integer from 0-32; Y is a counter-ion, the type of which is dependent on the charge z of the complex which can be positive, zero or negative; q = z/[charge Y]; and L is a ligand which is an organic molecule containing a number of hetero-atoms selected from N, P, O, and S, which co-ordinates via all or some of its hetero-atoms and/or carbon atoms to the Mn<(IV)>-center(s), which latter are anti-ferromagnetically coupled.
