Description

Bleichmittel, die aktiven Sauerstoff freisetzen, sind ein wesentlicher Bestandteil moderner Wasch- und Reinigungsmittel. Ihre Hauptaufgabe ist die Entfernung hartnäckiger Anschmutzungen wie Tee, Kaffee, Rotwein oder Fruchtsäften von textilen Fasern oder festen Oberflächen. Dies erfolgt durch oxidative Zerstörung des chromophoren Systems; gleichzeitig werden anhaftende Mikroorganismen abgetötet und Geruchsstoffe neutralisiert.Bleaches that release active oxygen are an essential part of modern washing and cleaning agents. Its main task is to remove stubborn stains such as tea, coffee, red wine or fruit juices from textile fibers or solid surfaces. This is done by oxidative destruction of the chromophoric system; At the same time, adhering microorganisms are killed and odorants neutralized.

Als bleichendes Agens werden meist Wasserstoffperoxid, organische oder anorganische Persäure verwendet. In pulverförmigen Produkten wird als Quelle für aktiven Sauerstoff meist ein Persalz eingesetzt. Typische Beispiele dafür sind Natriumperborate oder -percarbonate oder Harnstoffaddukte.Hydrogen peroxide, organic or inorganic peracid are mostly used as bleaching agents. A persalt is usually used as a source of active oxygen in powdery products. Typical examples are sodium perborates or percarbonates or urea adducts.

Um die Wirksamkeit dieser Perverbindungen im Temperaturbereich von 40 bis 60°C zu steigern, werden vielfach Bleichaktivatoren zugesetzt. Beispiele hierfür sind Tetraacetylethylendiamin (TAED), Diacetyldioxohexahydrotriazin (DADHT), Pentaacetylglycose (PAG), Benzoyloxibenzolsulfonat (BOBS) und Nonanoyloxibenzolsulfonat (NOBS). In Gegenwart des Aktivators werden aus den Persalzen die entsprechenden Persäuren freigesetzt, die meist ein breiteres Wirkspektrum aufweisen als Wasserstoffperoxid.In order to increase the effectiveness of these per compounds in the temperature range from 40 to 60 ° C., bleach activators are often added. Examples include tetraacetylethylenediamine (TAED), diacetyldioxohexahydrotriazine (DADHT), pentaacetylglycose (PAG), benzoyloxibenzenesulfonate (BOBS) and nonanoyloxibenzenesulfonate (NOBS). In the presence of the activator, the corresponding peracids are released from the persalts, which usually have a broader activity spectrum than hydrogen peroxide.

In vielen Fällen führt aber auch die Kombination eines Persalzes mit einem Aktivator noch nicht zu den optimalen Bleicheigenschaften. Problematisch ist insbesondere die eingeschränkte Wirksamkeit solcher Bleichsysteme bei niederen Anwendungstemperaturen und ihre fehlende Reaktivität gegenüber bestimmten Anschmutzungen.In many cases, however, the combination of a persalt with an activator does not yet lead to the optimal bleaching properties. A particular problem is the limited effectiveness of such bleaching systems at low application temperatures and their lack of reactivity to certain types of soiling.

Wünschenswert sind daher Systeme mit weiter gesteigerter Leistung. Aus ökonomischen und ökologischen Gründen werden katalytisch wirkende Additive bevorzugt. Daneben besteht aber auch ein Bedarf an Katalysatoren, die direkt mit Wasserstoffperoxid oder Caroaten reagieren und durch die die Aktivatorkonzentration deutlich reduziert oder überflüssig wird.Systems with further increased performance are therefore desirable. For economic and ecological reasons, catalytically active additives are preferred. However, there is also a need for catalysts which react directly with hydrogen peroxide or caroates and which significantly reduce or eliminate the activator concentration.

Es ist seit vielen Jahren bekannt, daß Übergangsmetalle in freier oder komplexierter Form die Zersetzung von Wasserstoffperoxiden katalysieren. Die Wirksamkeit der bisher beschriebenen Verbindungen ist aber in den meisten Fällen unbefriedigend. Vielfach führt der Zusatz von Metallsalzen zwar zu einer katalytischen Zersetzung des Wasserstoffperoxids, ein Bleicheffekt wird jedoch nicht beobachtet. Meist ist dies mit einer Schädigung des textilen Gewebes verbunden. Das Auftreten freier Übergangsmetalle während des Wasch- und Reinigungsprozesses ist daher unerwünscht. Wird dagegen das Metallsalz in komplexierter Form verwendet muß der entsprechende Komplex während der Lagerung und unter Anwendungsbedingungen hydrolyse- und oxidationsstabil sein, um diese Nebenwirkungen zu unterdrücken.It has been known for many years that transition metals in free or complex form catalyze the decomposition of hydrogen peroxides. The effectiveness of the compounds described so far is unsatisfactory in most cases. In many cases, the addition of metal salts leads to catalytic decomposition of the hydrogen peroxide, but no bleaching effect is observed. This is usually associated with damage to the textile fabric. The occurrence of free transition metals during the washing and cleaning process is therefore undesirable. If, on the other hand, the metal salt is used in complexed form, the corresponding complex must be stable to hydrolysis and oxidation during storage and under conditions of use in order to suppress these side effects.

Komplexe des Kupfers oder Cobalts mit Pyridincarbonsäure oder -dicarbonsäure sind in US 3,156,654 beschrieben. US 3,532,634 lehrt die Verwendung von Picolinsäuren, Pyrrolidincarbonsäuren oder Phenanthrolin. In US 4,430,243 werden EDTA und EDTMP-Komplexe von Kupfer, Eisen und Mangan als Bleichkatalysatoren beansprucht, nach US 4,478,733 können Mangansalze in Waschmittelformulierungen auf Basis Zeolith/Ortophosphat erfolgreich verwendet werden. Als effektive Komplexierungsmittel für Übergangsmetalle wurden zudem Hydroxicarbonsäuren (EP A 237 111), Porphinsysteme (EP A 306 089), 2,2'-Bispyridylamine (EP A 392 592), Salen-Derivate (EP A 408 131), makrocyclische Polyamine (EP A 439 387) oder Polyole wie Sorbitol (EP A 443 651) beschrieben. Aus ökologischen Gründen wird meist Mangan als Zentralatom gewählt, daneben sind aber auch Komplexe von Eisen, Kupfer und Cobalt bekannt.Complexes of copper or cobalt with pyridine carboxylic acid or dicarboxylic acid are described in US 3,156,654. US 3,532,634 teaches the use of picolinic acids, pyrrolidine carboxylic acids or phenanthroline. US 4,430,243 claims EDTA and EDTMP complexes of copper, iron and manganese as bleaching catalysts; US 4,478,733 successfully uses manganese salts in detergent formulations based on zeolite / ortophosphate. Hydroxyarboxylic acids (EP A 237 111), porphine systems (EP A 306 089), 2,2'-bispyridylamines (EP A 392 592), salen derivatives (EP A 408 131), macrocyclic polyamines (EP A 439 387) or polyols such as sorbitol (EP A 443 651). For ecological reasons, manganese is mostly chosen as the central atom, but complexes of iron, copper and cobalt are also known.

EP A 458 397 und 458 398 beschreibt die Verwendung von macrocyclischen Polyaminen als Komplexliganden in mehrkernigen, sauerstoffverbrückten Mangankomplexen. Diese Komplexe zeigen in Kombination mit Oxidationsmitteln, insbesondere an Tee-Anschmutzungen, gute Bleicheigenschaften. Als nachteilig wirkt sich allerdings der schwer zugängliche Komplexligand vom Triazacyclononan-Typ aus. Er ist nur in einem mehrstufigen, nebenproduktreichen Herstellprozeß zugänglich. In EP 544 519 sind ähnliche Komplexe beschrieben, wiederum ist die Synthese des Komplexliganden sehr aufwendig und großtechnisch schwer zu realisieren.EP A 458 397 and 458 398 describes the use of macrocyclic polyamines as complex ligands in multinuclear, oxygen-bridged manganese complexes. In combination with oxidizing agents, especially on tea stains, these complexes show good bleaching properties. However, the difficult to access complex ligand of the triazacyclononane type has a disadvantage. It is only accessible in a multi-stage, by-product-rich manufacturing process. Similar complexes are described in EP 544 519, again the synthesis of the complex ligand is very complex and difficult to implement on an industrial scale.

Es besteht daher auch weiterhin ein Bedarf an einfach herzustellenden, effektiven Bleichkatalysatoren mit breiten Wirkspektren zum Einsatz in Wasch- und Reinigungsmitteln.There is therefore still a need for easy-to-produce, effective bleaching catalysts with a broad spectrum of activity for use in detergents and cleaning agents.

Überraschenderwise wurde nun gefunden, daß sich die im folgenden beschriebenen Mangankomplexsalze ausgezeichnet zum Einsatz in Wasch- und Reinigungsmitteln eignen und bereits in katalytischen Mengen die Wirksamkeit von Wasserstoffperoxid, Peressigsäure und anderen Bleichsystemen um ein Mehrfaches steigern. Von besonderem Vorteil gegenüber dem Stand der Technik erweist sich die leichte Zugänglichkeit dieser Katalysatoren.Surprisingly, it has now been found that the manganese complex salts described below are excellently suitable for use in detergents and cleaning agents and increase the effectiveness of hydrogen peroxide, peracetic acid and other bleaching systems by a multiple even in catalytic amounts. The easy accessibility of these catalysts has proven to be particularly advantageous over the prior art.
