Title:
ACTIVATION OF BLEACH
Document Type and Number:
Japanese Patent JP2613707
Kind Code:
B2
Abstract:
PURPOSE: To obtain a novel bleach and an oxidation catalyst, to provide a method for bleaching a substrate using the oxidation catalyst and a bleaching (detergent) compsn. contg. the catalyst.
CONSTITUTION: The catalyst is a manganese-based co-ordination complex of the general formula: [LnMnmXp]2Yq wherein Mn is manganese in IV-oxidation state; (n) and (m) are independent integers of 2-8; X represents a co-ordination or bringing species; (p) is an integer of 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 org. molecule contg. a number of heteto-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), where L is anti-ferromangnetically coupled.
