Weiterhin betrifft die Verwendung der Metall-Komplexe I als Bleich- und Oxidationskatalysatoren, insbesondere in Wasch- und Reinigungsmitteln und bei der Textil- und Papierbleiche, sowie ein Verfahren zum Bleichen von verschmutzten Substraten unter Verwendung dieser Metall-Komplexe und diese Metall-Komplexe enthaltende Wasch- und Reinigungsmittel-Formulierungen. Furthermore, the use of the metal complexes I as bleaching and oxidation catalysts, in particular in detergents and cleaning agents and in textile and paper bleaching, relates to a process for bleaching contaminated substrates using these metal complexes and washing containing these metal complexes - and detergent formulations.
Peroxidbleichmittel in wäßrigen Wasch- und Reinigungsmitteln, insbesondere für die Textilwäsche, sind seit langem bekannt. Peroxide bleaching agents in aqueous washing and cleaning agents, in particular for textile washing, have long been known.
Solche Mittel entfalten ihre Wirkung, beispielsweise die Such agents are effective, for example
Entfernung von Tee-, Obst- oder Rotwein-Verschmutzungen von Textilien, am besten bei Temperaturen von 60 bis 100°C; bei Temperaturen unterhalb 60°C ist ihre Wirkung stark eingeschränkt.
Es ist bekannt, daß viele Übergangsmetall-Ionen die Zersetzung von Wasserstoffperoxid oder Wasserstoffperoxid freisetzenden Verbindungen wie Natriumperborat katalysieren. Es ist auch vorgeschlagen worden, daß Übergangsmetallsalze zusammen mit chelatisierenden Verbindungen zur Aktivierung von Peroxidbleichmitteln gerade bei niedrigen Temperaturen eingesetzt werden können. Dabei erweist sich nicht jede Kombination von Übergangsmetall und chelatisierender Verbindung als wirksam und die Wirksamkeit einer speziellen Kombination als Bleichkatalysator ist nicht voraussagbar. Removal of tea, fruit or red wine soiling from textiles, preferably at temperatures from 60 to 100 ° C; at temperatures below 60 ° C their effect is severely limited. Many transition metal ions are known to catalyze the decomposition of hydrogen peroxide or compounds releasing hydrogen peroxide, such as sodium perborate. It has also been suggested that transition metal salts can be used together with chelating compounds to activate peroxide bleaching agents, especially at low temperatures. Not every combination of transition metal and chelating compound proves to be effective, and the effectiveness of a special combination as a bleaching catalyst cannot be predicted.
In den Schriften EP-A 458 397 (1), EP-A 458 398 (2) und In the documents EP-A 458 397 (1), EP-A 458 398 (2) and

The ligands L used are mainly aliphatic macrocycles with 3 or 4
Heteroatomen, meist Stickstoffatomen, die an der freien Bindung Wasserstoff oder eine Methylgruppe tragen, verwendet. Die in (1) bis (3) beschriebenen Mangan-Komplexe sind in ihrer Wirksamkeit, Stabilität und Verträglichkeit als Bleichkatalysatoren jedoch noch nicht voll befriedigend. Außerdem weisen sie Nachteile anderer Art auf, so insbesondere ihre aufwendige und kostenspielige Herstellung. Heteroatoms, mostly nitrogen atoms, which carry hydrogen or a methyl group on the free bond. However, the effectiveness, stability and compatibility of the manganese complexes described in (1) to (3) as bleaching catalysts are not yet completely satisfactory. In addition, they have disadvantages of another kind, in particular their complex and costly production.
Aufgabe der vorliegenden Erfindung war es daher, Bleichkatalysatoren mit verbesserter Wirksamkeit bereitzustellen, die außerdem die Mängel der im Stand der Technik beschriebenen Systeme nicht mehr aufweisen. The object of the present invention was therefore to provide bleaching catalysts with improved effectiveness, which moreover no longer have the deficiencies of the systems described in the prior art.

Die erfindungsgemäßen ein- oder mehrkernigen Metall-Komplexe I eignen sich in hervorragender Weise als Bleich- und Oxidations-katalysatoren, insbesondere in Wasch- und Reinigungsmitteln und bei der Textil- und Papierbleiche. Besonders hervorzuheben sind hier Textilwaschmittel in Form von Pulverwaschmitteln oder als flüssige Formulierungen und Geschirreinigungsmittel. Ein Vorteil der erfindungsgemäßen Bleichkatalysatoren ist dabei ihre Stabilitat gegenüber Hydrolyse und Oxidation. Die Metall-Komplexe I selbst besitzen die katalytische Aktivität und sind insbesondere in einer Vielzahl von Textilwaschmittelformulierungen hochwirksam. Sie verbessern in solchen Formulierungen nicht nur die Bleichwirkung von Wasserstoffperoxid, sondern auch von organisehen und anorganischen Peroxysäure-Verbindungen. The mono- or multinuclear metal complexes I according to the invention are outstandingly suitable as bleaching and oxidation catalysts, in particular in detergents and cleaning agents and in textile and paper bleaching. Textile detergents in the form of powder detergents or as liquid formulations and dishwashing detergents are particularly noteworthy. One advantage of the bleaching catalysts according to the invention is their stability to hydrolysis and oxidation. The metal complexes I themselves have the catalytic activity and are particularly effective in a large number of textile detergent formulations. In such formulations, they not only improve the bleaching effect of hydrogen peroxide, but also of organic and inorganic peroxyacid compounds.
Als weitere anwendungstechnische Vorteile, insbesondere in As further application technology advantages, especially in
Textilwaschmittelformulierungen, sind zu nennen ihre universelle Wirksamkeit bei der Entfernung aller Arten von Verschmutzungen, sowohl hydrophiler als auch hydrophober Natur, und ihre Vertrag
lichkeit mit den üblichen Waschmittel-Enzymen wie Proteasen, Cellulasen, Lipasen, Amylasen oder Oxidasen. Textile detergent formulations are worth mentioning for their universal effectiveness in removing all types of soiling, both hydrophilic and hydrophobic, and their contract with the usual detergent enzymes such as proteases, cellulases, lipases, amylases or oxidases.
Gegenstand der vorliegenden Erfindung ist demgemäß auch ein Verfahren zum Bleichen von verschmutzten Substraten, welches dadurch gekennzeichnet ist, daß man das verschmutzte Substrat in wäßriger Bleichflotte mit Peroxyverbindungen und einer wirksamen Menge eines oder mehrerer ein- oder mehrkerniger Metall-Komplexe I als Bleichkatalysatoren in Kontakt bringt, um miteinander zu wechselwirken und eine Reinigungswirkung auf dem Substrat zu erzielen. The present invention accordingly also relates to a process for bleaching soiled substrates, which is characterized in that the soiled substrate is brought into contact with peroxy compounds and an effective amount of one or more mononuclear or multinuclear metal complexes I as bleaching catalysts in an aqueous bleaching liquor to interact with each other and achieve a cleaning effect on the substrate.

Höhere Metall-Gehalte, etwa bis zu 500 ppm, können bei industriellen Bleichprozessen, beispielsweise auf dem Textil- oder Papiersektor, zweckmäßig sein. Die zuerst genannten niedrigen Metall-Gehalte beziehen sich vornehmlich auf Haushaltstextilwaschmittel. The aqueous bleaching liquor preferably contains these metal complexes, based on the weight of the bleaching liquor, in an amount of 0.001 to 100 ppm of metal, in particular 0.01 to 20 ppm of metal, especially 0.03 to 10 ppm of metal (ppm means " parts per million "by weight). Higher metal contents, for example up to 500 ppm, can be useful in industrial bleaching processes, for example in the textile or paper sector. The first low metal contents mentioned refer primarily to household textile detergents.
Wäßrige Wasch- und Bleichflotten, die Peroxyverbindungen und die erfindungsgemaßen Bleichkatalysatoren enthalten, sind im neutralen und alkalischen pH-Bereich, also von ca. pH 7 bis pH 14, wirksam. Ein WirkungsOptimum liegt bei pH 8 bis pH 11. Aqueous washing and bleaching liquors which contain peroxy compounds and the bleaching catalysts according to the invention are effective in the neutral and alkaline pH range, that is to say from about pH 7 to pH 14. An optimum effect is at pH 8 to pH 11.
