Use of transition metal complexes as bleach catalysts

   
   

The use of compounds of the formula (1) M(L).sub.n X.sub.m (1) where M is a metal atom from the group Mn, Fe, Co, Ni, Mo, W, L is a ligand from the group of nitrogen-containing heterocycles, X is chloride, bromide, nitrate, perchlorate, sulfate, ammonia, tetrafluoroborate, hexafluorophosphate or an anion of an organic acid having 1 to 22 carbon atoms, n is a number from 2 to 4 and m is a number from 0 to 4, as catalyst for peroxygen compounds, in particular in washing, bleaching and cleaning compositions is claimed.

L'utilisation des composés de la formule (1) M(L).sub.n X.sub.m (1) où M est un atome en métal du manganèse de groupe, Fe, Co, Ni, MOIS, W, L est un ligand du groupe de heterocycles contenant de l'azote, X est chlorure, bromure, nitrate, perchlorate, sulfate, ammoniaque, tetrafluoroborate, hexafluorophosphate ou un anion d'un acide organique ayant 1 à 22 atomes de carbone, n est un nombre de 2 à 4 et m est un nombre de 0 à 4, car le catalyseur pour des composés de peroxyde, en particulier en compositions en lavage, en blanchissement et en nettoyage est réclamé.
