Definitions
- the present invention relates to the use of certain manganese complexes as catalysts for reactions with peroxygen compounds for bleaching colored stains on hard surfaces.
- Hard surface cleaners containing such catalysts are another subject of the invention.
- Inorganic peroxygen compounds especially hydrogen peroxide and solid peroxygen compounds, which dissolve in water to release hydrogen peroxide, such as sodium perborate and sodium carbonate perhydrate, have long been used as oxidizing agents for disinfection and bleaching purposes.
- the oxidizing effect of these substances in dilute solutions depends strongly on the temperature. For example, with H 2 O 2 or perborate in alkaline bleaching liquors, sufficiently quick bleaching of soiled textiles can only be achieved at temperatures above about 80 ° C. At lower temperatures, the oxidation effect of the inorganic peroxygen compounds can be improved by adding so-called bleach activators, for which numerous proposals have become known in the literature.

Description
MANGANKOMPLEXE ALS KATALYSATOREN FÜR PERSAUERSTOFFVERBINDUNGEN ZUR REINIGUNG VON HARTEN OBERFLÄCHEN INSBESONDERE VON GESCHIRRMANGANE COMPLEXES AS CATALYSTS FOR PERCENTAGE COMPOUNDS FOR CLEANING HARD SURFACES, IN PARTICULAR DISHES
Die vorliegende Erfindung betrifft die Verwendung von bestimmten Mangankomplexen als Katalysatoren für Reaktionen mit Persauerstoffverbindungen zum Bleichen von gefärbten Anschmutzungen an harten Oberflächen. Reinigungsmittel für harte Oberflächen, die derartige Katalysatoren enthalten, stellen einen weiteren Erfindungsgegenstand dar.The present invention relates to the use of certain manganese complexes as catalysts for reactions with peroxygen compounds for bleaching colored stains on hard surfaces. Hard surface cleaners containing such catalysts are another subject of the invention.
Anorganische Persauerstoffverbindungen, insbesondere Wasserstoffperoxid und feste Persauerstoffverbindungen, die sich in Wasser unter Freisetzung von Wasserstoffperoxid lösen, wie Natriumperborat und Natriumcarbonat-Perhydrat, werden seit langem als Oxidationsmittel zu Desinfektions- und Bleichzwecken verwendet. Die Oxidationswirkung dieser Substanzen hängt in verdünnten Lösungen stark von der Temperatur ab. So erzielt man beispielsweise mit H2O2 oder Perborat in alkalischen Bleichflotten erst bei Temperaturen oberhalb von etwa 80° C eine ausreichend schnelle Bleiche verschmutzter Textilien. Bei niedrigeren Temperaturen kann die Oxidationswirkung der anorganischen Persauerstoffverbindungen durch Zusatz sogenannter Bleichaktivatoren verbessert werden, für die zahlreiche Vorschläge in der Literatur bekannt geworden sind. Es handelt sich vor allem um Verbindungen aus den Stoffklassen der N- oder O-Acylverbindungen, beispielsweise mehrfach acylierte Alkylendiamine, insbesondere Tetraacetylethylendiamin, acylierte Glykolurile, insbesondere Tetraacetylglykoluril, N-acylierte Hydantoine, Hydrazide, Triazole, Hydrotriazine, Urazole, Diketopiperazine, Sulfurylamide und Cyanurate, ausserdem um Carbonsäureanhydride, insbesondere Phthalsäureanhydrid, Carbonsäureester, insbesondere Natrium-nonanoyloxy-benzolsulfonat, Natrium-isononanoyloxy-benzolsulfonat und acylierte Zuckerderivate, wie Pentaacetylgiukose. Durch Zusatz dieser Substanzen kann die Bleichwirkung wässriger Peroxidflotten so weit gesteigert werden, dass bereits bei Temperaturen um 60° C im wesentlichen die gleichen Wirkungen wie mit der Peroxidflotte allein bei 95° C eintreten.Inorganic peroxygen compounds, especially hydrogen peroxide and solid peroxygen compounds, which dissolve in water to release hydrogen peroxide, such as sodium perborate and sodium carbonate perhydrate, have long been used as oxidizing agents for disinfection and bleaching purposes. The oxidizing effect of these substances in dilute solutions depends strongly on the temperature. For example, with H 2 O 2 or perborate in alkaline bleaching liquors, sufficiently quick bleaching of soiled textiles can only be achieved at temperatures above about 80 ° C. At lower temperatures, the oxidation effect of the inorganic peroxygen compounds can be improved by adding so-called bleach activators, for which numerous proposals have become known in the literature. These are primarily compounds from the substance classes of the N- or O-acyl compounds, for example multiply acylated alkylenediamines, in particular tetraacetylethylenediamine, acylated glycolurils, in particular tetraacetylglycoluril, N-acylated hydantoins, hydrazides, triazoles, hydrotriazines, urazoles, diketopamide and sulfuryl cyanuryl amides , in addition to carboxylic acid anhydrides, in particular phthalic anhydride, carboxylic acid esters, in particular sodium nonanoyloxy-benzenesulfonate, sodium isononanoyloxy-benzenesulfonate and acylated sugar derivatives, such as pentaacetyl glucose. By adding these substances, the bleaching effect of aqueous peroxide liquors can be increased to such an extent that even at temperatures around 60 ° C essentially the same effects occur as with the peroxide liquor alone at 95 ° C.
Auch diese Temperaturen sind für das manuelle Reinigen harter Oberflächen, beispielweise von Geschirr, noch zu hoch und werden normalerweise auch in maschinellen Geschirrspül- verfahren nicht immer erreicht. Im Bemühen um energiesparende Verfahren zum maschinellen Reinigen von Geschirr gewinnen in den letzten Jahren Anwendungstemperaturen von unterhalb 60° C, insbesondere unterhalb 50° C bis hinunter zur Kaltwassertemperatur, an Bedeutung.
Bei diesen niedrigen Temperaturen lässt die Wirkung der bisher bekannten Aktivatorverbindungen in der Regel erkennbar nach, besonders bei schwer bleichbaren Anschmutzungen, wie beispielsweise Teerückständen auf Porzellan oder Glas. Es hat deshalb nicht an Bestrebungen gefehlt, für diesen Temperaturbereich wirksamere Aktivatoren zu entwickeln, ohne dass bis heute ein überzeugender Erfolg zu verzeichnen gewesen wäre.These temperatures, too, are still too high for manual cleaning of hard surfaces, for example dishes, and are usually not always reached even in automatic dishwashing processes. In the past few years, application temperatures of below 60 ° C., in particular below 50 ° C., down to the cold water temperature have become increasingly important in the search for energy-saving methods for machine cleaning of dishes. At these low temperatures, the effect of the activator compounds known to date generally diminishes noticeably, particularly in the case of soiling which is difficult to bleach, such as, for example, tea residues on porcelain or glass. There has been no shortage of efforts to develop more effective activators for this temperature range without convincing success to date.
Ein Ansatzpunkt dazu könnte sich durch den Einsatz von Übergangsmetallsalzen und -komplexen als sogenannte Bleichkatalysatoren ergeben. Aus DE-A-19529904 und WO 97/07191 sind bereits Reinigungsmittel für Geschirr bekannt, die Übergangsmetallkomplexe vom Salen-Typ als Aktivator für Persauerstoffverbindungen enthalten. Auch diese vermögen jedoch noch nicht, allen Anforderungen gerecht zu werden.One starting point could be the use of transition metal salts and complexes as so-called bleaching catalysts. From DE-A-19529904 and WO 97/07191 cleaning agents for dishes are already known which contain transition metal complexes of the salen type as an activator for peroxygen compounds. However, even these are not yet able to meet all requirements.
Es wurde nun gefunden, dass überraschenderweise Mangankomplexe der nachstehenden Formeln eine deutlich verbesserte bleichkatalysierende Wirkung auf gefärbte Anschmutzungen haben, die sich an harten Oberflächen befinden. Werden diese Komplexe in katalytischen Mengen zu einem Geschirrspülmittel gegeben, das eine Persauerstoffverbindung und gegebenenfalls TAED (N,N,N',N'-Tetraacetylethylendiamin) enthält, so werden Teeanschmutzungen an Porzellan bei 45° C in der Geschirrspülmaschine weitgehend entfernt. Dies gilt auch bei Verwendung von Hartwasser, wo bekanntlich die Entfernung von Teebelag schwieriger zu erreichen ist als in Weichwasser.It has now been found that, surprisingly, manganese complexes of the formulas below have a significantly improved bleach-catalyzing effect on colored soils which are found on hard surfaces. If these complexes are added in catalytic amounts to a dishwashing detergent which contains a peroxygen compound and optionally TAED (N, N, N ', N'-tetraacetylethylenediamine), tea stains on porcelain at 45 ° C. are largely removed in the dishwasher. This also applies when using hard water, where it is known that the removal of tea deposits is more difficult to achieve than in soft water.

Weiterhin betrifft die Erfindung Reinigungsmittel für harte Oberflächen insbesondere Reinigungsmittel für Geschirr und unter diesen vorzugsweise solche für den Einsatz in maschinellen Reinigungsverfahren, die eine der oben beschriebenen Verbindungen der Formel (1) oder (2) als Bleichkatalysator enthalten, und ein Verfahren zur Reinigung von harten Oberflächen, insbesondere von Geschirr, unter Einsatz eines derartigen Bleichkatalysators.The invention further relates to detergents for hard surfaces, in particular detergents for dishes, and preferably those for use in machine cleaning processes which contain one of the compounds of the formula (1) or (2) described above as a bleaching catalyst, and a process for cleaning hard surfaces Surfaces, especially of dishes, using such a bleaching catalyst.
Die erfindungsgemässe Verwendung besteht im wesentlichen darin, in Gegenwart einer mit gefärbten Anschmutzungen verunreinigten harten Oberfläche Bedingungen zu schaffen, unter denen ein peroxidhaltiges Oxidationsmittel und der Bleichkatalysator gemäss Formel (1) oder (2) miteinander reagieren können, mit dem Ziel stärker oxidierend wirkende Folgeprodukte zu erhalten. Solche Bedingungen liegen insbesondere dann vor, wenn beide Reaktionspartner in wässriger Lösung aufeinander treffen. Dies kann durch separate Zugabe der Persauerstoffverbindung und des Bleichkatalysators zu einer gegebenenfalls reinigungsmittelhaitigen Lösung geschehen. Besonders vorteilhaft wird das erfindungsgemässe Verfahren jedoch unter Verwendung eines erfindungsgemässen Reinigungsmittels für harte Oberflächen, das den Bleichkatalysator und ein persauerstoffhaltiges Oxidationsmittel enthält, durchgeführt. Die Persauerstoffverbindung kann auch separat, in Substanz oder als vorzugsweise wässrige Lösung oder Suspension, zur Lösung zugegeben werden, wenn ein peroxidfreies Reinigungsmittel verwendet wird.
Je nach Verwendungszweck können die Bedingungen weit variiert werden. So kommen neben rein wässrigen Lösungen auch Mischungen aus Wasser und geeigneten organischen Lösungsmitteln als Reaktionsmedium in Frage. Die Einsatzmengen an Persauerstoffverbindungen werden im allgemeinen so gewählt, dass in den Lösungen zwischen 10 ppm und 10 % Aktivsauerstoff, vorzugsweise zwischen 50 ppm und 5 000 ppm Aktivsauerstoff vorhanden sind. Auch die verwendete Menge an Bleichkatalysator hängt vom Anwendungszweck ab. Je nach gewünschtem Aktivierungsgrad werden 0,00001 Mol bis 0,025 Mol, vorzugsweise 0,0001 Mol bis 0,02 Mol Aktivator pro Mol Persauerstoffverbindung verwendet, doch können in besonderen Fällen diese Grenzen auch über- oder unterschritten werden.The use according to the invention essentially consists in creating, in the presence of a hard surface contaminated with colored soils, conditions under which a peroxide-containing oxidizing agent and the bleaching catalyst according to formula (1) or (2) can react with one another with the aim of producing secondary products with a stronger oxidizing action receive. Such conditions exist particularly when both reactants meet in aqueous solution. This can be done by separately adding the peroxygen compound and the bleaching catalyst to an optionally detergent-containing solution. However, the method according to the invention is particularly advantageously carried out using a cleaning agent according to the invention for hard surfaces, which contains the bleaching catalyst and an oxidizing agent containing peroxygen. The peroxygen compound can also be added to the solution separately, in bulk or as a preferably aqueous solution or suspension, if a peroxide-free cleaning agent is used. The conditions can be varied widely depending on the intended use. In addition to purely aqueous solutions, mixtures of water and suitable organic solvents are also suitable as the reaction medium. The amounts of peroxygen compounds used are generally selected so that the solutions contain between 10 ppm and 10% active oxygen, preferably between 50 ppm and 5,000 ppm active oxygen. The amount of bleaching catalyst used also depends on the application. Depending on the desired degree of activation, 0.00001 mol to 0.025 mol, preferably 0.0001 mol to 0.02 mol, of activator are used per mol of peroxygen compound, but these limits can also be exceeded or fallen below in special cases.

Beispiele hierfür sind Tetranatriumdiphosphat, Dinatriumdihydrogendiphosphat, Pen- tanatriumtriphosphat, Natriumtripoiyphosphat, sogenanntes Natriumhexametaphosphat sowie die entsprechenden Kaliumsalze sowie Gemische aus Natrium- und Kaliumsalzen. Ihre Mengen können im Bereich von bis zu etwa 35 Gew. %, bezogen auf das gesamte Mittel liegen. Weitere mögliche wasserlösliche Builderkomponenten sind zum Beispiel organische Polymere nativen oder synthetischen Ursprungs, vor allem Polycarboxylate, die insbesondere in Hartwasserregionen als Co-Builder wirken.In principle, all builders commonly used in machine dishwashing detergents, for example polymeric alkali metal phosphates, which can be present in the form of their alkaline, neutral or acidic sodium or potassium salts, are suitable as water-soluble builder components, in particular in such low-alkaline cleaning agents. Examples include tetrasodium diphosphate, disodium dihydrogen diphosphate, pentasodium triphosphate, sodium tripolyphosphate, so-called sodium hexametaphosphate and the corresponding potassium salts and mixtures of sodium and potassium salts. Their amounts can range up to about 35% by weight, based on the total agent. Other possible water-soluble builder components are, for example, organic polymers of native or synthetic origin, especially polycarboxylates, which act as co-builders, particularly in hard water regions.
In Betracht kommen beispielsweise Polyacrylsäuren und Copolymere aus Maleinsäureanhydrid und Acrylsäure sowie die Natriumsalze dieser Polymersäuren. Handelsübliche Produkte sind zum Beispiel Sokalan® CP 5 und PA 30 der Firma BASF. Zu den als Co- Builder brauchbaren Polymeren nativen Ursprungs gehören beispielsweise oxidierte Stärke, wie zum Beispiel aus der internationalen Patentanmeldung WO 94/05762 bekannt, und Polyaminosäuren wie Polyglutaminsäure oder Polyasparaginsäure.

In Abhängigkeit vom letztlich in den erfindungsgemässen

Als Bleichmittel auf Sauerstoffbasis kommen in erster Linie Alkaliperboratmono- beziehungsweise -tetrahydrat und/oder Alkalipercarbonat in Betracht, wobei Natrium das bevorzugte Alkalimetall ist.

Zusätzlich oder insbesondere alternativ können auch bekannte Peroxycarbonsäuren, zum Beispiel Dodecandipersäure oder Phthalimidopercarbonsäuren, die gegebenenfalls am Aromaten substituiert sein können, enthalten sein.

In addition, the addition of small amounts of known bleach stabilizers such as, for example, phosphonates, borates or metaborates and metasilicates, and magnesium salts such as magnesium sulfate may also be useful.

Beispiel 1 : Anschmutzunαsprozedere: Ein Teesud (12g Teeblätter/Liter) wird unter Rühren bei 99° C aus Schwarztee (Marke Twinings) und Hartwasser (Gesamthärte: 18° dH) hergestellt. Man lässt fünf Minuten ziehen und filtriert den Tee. Es werden dann ca. 100 ml Tee in eine Porzellantasse gegossen. Der Tee wird 30 Minuten in den Tassen stehen gelassen. Die Tassen werden anschliessend in drei Schritten von ca. 35 ml entleert. Zwischen den Entleerungsschritten wird jeweils fünf Minuten gewartet. Die völlig entleerten Tassen werden 60 Minuten bei 70° C getrocknet.
Reiniαunαsprozedere: Die Tassen wurden in einem Miele G-690 D Geschirrspüler mit dem Fθinprogramm bei 45°C unter Verwendung von Hartwasser gereinigt. Bei jedem Reinigungsprogramm wurden jeweils 12 mit Tee angeschmutzte Tassen gereinigt. Ausserdem befanden sich sechs Gläser mit Milchanschmutzungen, 24 saubere Teller und 60 g von einer Mischung verschiedener Lebensmittel (u. a. Spinat, Eier, Hackfleisch, Stärke)in der Maschine. Die Dosierung des Geschirrspülmittels war: 17.2 g einer phosphathaltigen Grundformulierung, 1.72g Natriumperborat-monohydrat, 0.8 g TAED und ggf. 50 ppm Katalysator (ppm bezogen auf das Metall). Nach der Reinigung wurde die Entfernung des Teebelags visuell auf einer Skala von 0 (=unverändert sehr starker Belag) bis 10 (=kein Belag) benotet. In Tabelle 1 werden die Noten für unsere Katalysatoren verglichen mit einer Referenz (nur TAED, kein Katalysator). Die in der Tabelle angegebenen Noten sind die Medianwerte aus mehreren Reinigungsprogrammen mit je 12 Tassen. Die Tabelle zeigt, dass die Noten für die erfindungsgemäss verwendeten Katalysatoren signifikant besser sind als der Referenzwert.Example 1: Soiling procedure: A tea infusion (12 g tea leaves / liter) is made from black tea (Twinings brand) and hard water (total hardness: 18 ° dH) with stirring at 99 ° C. Allow to infuse for five minutes and filter the tea. Then about 100 ml of tea are poured into a porcelain cup. The tea is left in the cups for 30 minutes. The cups are then emptied in three steps of approx. 35 ml. There is a waiting period of five minutes between the emptying steps. The completely empty cups are dried at 70 ° C for 60 minutes. Reiniαunαsprozedere: The cups were cleaned in a Miele G-690 D dishwasher with the Fθin program at 45 ° C using hard water. In each cleaning program, 12 cups soiled with tea were cleaned. There were also six glasses with milk soiling, 24 clean plates and 60 g of a mixture of different foods (including spinach, eggs, minced meat, starch) in the machine. The dosage of the dishwashing detergent was: 17.2 g of a basic formulation containing phosphate, 1.72 g of sodium perborate monohydrate, 0.8 g of TAED and possibly 50 ppm of catalyst (ppm based on the metal). After cleaning, the removal of the tea topping was assessed visually on a scale from 0 (= unchanged very thick deposit) to 10 (= no deposit). Table 1 compares the scores for our catalysts with a reference (TAED only, no catalyst). The notes given in the table are the median values from several cleaning programs with 12 cups each. The table shows that the marks for the catalysts used according to the invention are significantly better than the reference value.

Beispiel 2:Example 2:
10.1 mg (30 μmol) Morin-Dihydrat wurde in 1000 ml einer Boraxpufferlösung (9 mmol Di- Natriumtetraborat/Liter, pH=9.4) gelöst. Bei t= 0 Min. wurde 295 mg (2.5 mmol) Natriumperborat-monohydrat und, je nach dem, 3.4 μmol Katalysator oder 137 mg (0.6
mmol) TAED zugegeben. Über einen Zeitraum von 30 Minuten wurde bei 27° C minütlich die Extinktion E der Lösung bei 400 nm gemessen. In Tabelle 2 sind die Werte für die prozentuale Entfärbung D(t), berechnet nach D(t)=[E(0)-E(t)]/E(0)*100, angegeben.10.1 mg (30 μmol) of morin dihydrate was dissolved in 1000 ml of a borax buffer solution (9 mmol disodium tetraborate / liter, pH = 9.4). At t = 0 min. 295 mg (2.5 mmol) sodium perborate monohydrate and, depending on the, 3.4 μmol catalyst or 137 mg (0.6 mmol) TAED added. The extinction E of the solution at 400 nm was measured every minute at 27 ° C. over a period of 30 minutes. Table 2 shows the values for the percent decolorization D (t), calculated according to D (t) = [E (0) -E (t)] / E (0) * 100.
Man erkennt, dass die Bleichwirkung in Lösung bei den Verbindungen (101) bis (104) besser ist als die von TAED, obwohl die Konzentration von TAED viel höher war. Ausserdem erkennt man, dass nach 30 Minuten eine bessere Entfärbung erreicht wird als mit der Verbindung M2.It can be seen that the bleaching action in solution for compounds (101) to (104) is better than that of TAED, although the concentration of TAED was much higher. You can also see that after 30 minutes a better decolorization is achieved than with the compound M2.
Beispiel 3: Arbeitet man wie im Beispiel 1 beschrieben, verwendet jedoch als Katalysator eine äquivalente Menge der Verbindung der FormelEXAMPLE 3 The procedure is as described in Example 1, but an equivalent amount of the compound of the formula is used as the catalyst

Example 4: The procedure is as described in Example 1 of EP-A-630964, but instead of salicylaldehyde, an equivalent amount of the 1: 1 mixture of salicylaldehyde and 2-hydroxy-4-diethylamino-benzaldehyde and instead of ethylenediamine, an equivalent amount of 2-amino-2-methyl-3-aminopropane. The manganese complex is then formed as described there, and a mixture of the following 4 manganese complexes is obtained:
Arbeitet man wie im Beispiel 1 beschrieben, verwendet jedoch als Katalysator eine äquivalente Menge dieser Mischung, so erhält man ebenfalls eine gute Reinigungswirkung.If the procedure described in Example 1 is followed, but an equivalent amount of this mixture is used as the catalyst, a good cleaning action is also obtained.
Beispiel 5: Ebenfalls gute Reinigungswirkung erzielt man, wenn man statt der Mischung aus Beispiel 4 eine solche einsetzt, die lediglich die beiden letzten der aufgeführten Komplexe enthält. Diese Mischung ist durch Reinigung der Mischung der unkomplexierten Liganden aus der ersten Stufe der Herstellung gemäss Beispiel 4 zugänglich.
Example 5: Another good cleaning effect is achieved if, instead of the mixture from Example 4, one is used which contains only the last two of the complexes listed.
