Description
- Die vorliegende Erfindung betrifft neue flüssige Waschmittel enthaltend gezielt disulfonierte Dibenzfuranylbiphenyle als optische Aufheller deren Herstellung und deren Verwendung.
- Die Verwendung von optischen Aufhellern in flüssigen Waschmitteln ist bekannt. Sie ziehen während der Behandlung auf das Waschgut auf und führen durch ihre spezielle Lichtabsorption/Emissionseigenschaft zu einer Elimination der gelblichen Töne bzw. zu einer Verbesserung des Weissgrades.
- Dieser Effekt ist aber auch verantwortlich für das Auftreten von hellen Flecken wenn Textilgewebe z.B. bei einer Vorbehandlung direkt mit dem flüssigen Waschmittel in Kontakt gerät.
- ln der EP-A-167 205 wird zur Lösung dieses Problems vorgeschlagen, monosulfonierte Stilbentriazolyl-, -triazin- oder Distyrylbiphenyl-Aufheller in anionischen Flüssigwaschmitteln zu verwenden.
- Ausserdem sind in der EP-A-364 027 flüssige Bleich- und Waschmittel offenbart, die sulfonierte Benzofuranylbiphenyl-Aufheller enthalten; in der EP-A-321 715 sind stabile Waschmittel beschrieben, die sulfonierte Benzofuranylbiphenyl-Aufheller enthalten; und in der US-A-4 002 423 sind neue sulfonierte Benzofuranylbiphenyl-Verbindungen offenbart, die Verwendung als Aufheller, insbesondere in Waschmitteln finden können. In keiner dieser Offenbarungen aber sind flüssige Waschmittel offenbart, die sulfonierte Benzofuranylbiphenyl-Aufheller mit einem C₁-C₄-Alkyl Substituent in dem Furanteil des Benzofuranylbiphenylmoleküls enthalten.
-
- Im einzelnen bedeutet: X C₁-C₄-Alkyl, Y und Z unabhängig voneinander ein Sulfonsäurerest, Wasserstoff, C₁-C₄-Alkyl, C₁-C₄-Alkoxy, Halogen, CN, Phenoxy, Benzyloxy, mit der Bedingung, dass entweder Y oder Z ein Sulfonsäurerest ist und die restlichen Substituenten nicht ein Sulfonsäurerest sind.
- Als Halogene kommen vor allem Fluor, Chlor und Brom in Frage, insbesondere jedoch Chlor.
- Als C₁-C₄-Alkylreste (bzw. C₁-C₄-Alkoxyreste) kommen unverzweigte oder verzweigte Alkyl- (bzw. Alkoxy-) reste in Betracht. Diese Alkyl- (bzw. Alkoxy-) reste können ihrerseits substituiert sein mit z.B. Aryl- (Phenyl-, Naphthyl-), C₁-C₄-Alkyl-, C₁-C₄-Alkoxy-, OH- oder CN-Gruppen.
-
- R₁ = Wasserstoff, C₁-C₄-Alkyl, Chlor, C₁-C₄-Alkoxy, Phenoxy oder Benzyloxy,
- R₂ = C₁-C₄-Alkyl und M = Wasserstoff und/oder ein Aequivalent eines nicht chromophoren Kations bedeuten.
- M in der Bedeutung eines nicht-chromophoren Kations steht vorzugsweise für Alkalimetall wie Lithium, Natrium, Kalium sowie gegebenenfalls substituiertes Ammonium wie Ammonium, Mono-, Di- oder Triethanolammonium, Mono-, Di- oder Tripropanolammonium oder Tri- oder Tetramethylammonium.
-
- Die optischen Aufheller können hergestellt werden, indem man
- a) ein Mol der Verbindung der Formel (X)
- b) ein Mol der Verbindung der Formel (X) mit mindestens stöchiometrischen Mengen Chlorsulfonsäure, in einem inerten organischen Lösungsmittel, bei Temperaturen von 0° bis 40°C umsetzt oder
- c) die Verbindung der Formel (X) mit konzentrierter Schwefelsäure oder mit Schwefelsäure/Eisessig bzw. Oleum/Eisessig auf Temperaturen von 40° bis 140°C erhitzt oder
- d) ein Mol 4,4'-Bis-(halogenmethyl)-biphenyl mit mindestens 2 Mol Salicylaldehyd oder deren Anile der Formel (XI) bzw. (XII)
- Die Ausgangsverbindungen der Formel (X),(XI) und (XII) sind bekannt und können nach bekannten Methoden hergestellt werden. Vorteilhafterweise wird das Verfahren d) jedoch als Eintopfverfahren ohne Isolierung der Zwischenprodukte (XIII) und (XIV) durchgeführt.
- Nach dem Verfahren (a) werden insbesondere die Verbindungen der Formel (III) hergestellt.
- Unter SO₃/Basen-Komplex sind Additionsverbindungen von SO₃ an organische Basen, z.B. Dioxan, vorzugsweise stickstoffhaltige Basen, wie zum Beispiel Triethylamin, N-Ethyldiisopropylamin, Dimethylformamid (DMF) und insbesondere Pyridin zu verstehen. Die Stabilität dieser Additionsverbindungen ist dabei entscheidend für den Sulfonierungsgrad. So werden bei Verwendung von 2 bis 6, insbesondere 3 bis 5 Mol SO₃/Pyridin-Komplex (bezogen auf den SO₃-Gehalt) pro Mol der Verbindung der Formel (X) hergestellt. SO₃/Basen-Komplexe sind bekannt und können nach bekannten Methoden hergestellt werden (E.E. Gilbert, E.P. Jones, Ind. Enging. Chem. 49, Nr. 9, Teil II,S. 1553 ff (1957); Beilstein 20, III/IV, 2232).

- Nach dem Verfahren c) werden insbesondere die Verbindungen der Formel (II) und (III) hergestellt.
- Die Veretherung bei Verfahren d) erfolgt bei Temperaturen von 60° bis 140°C und insbesondere 100° bis 120°C in bekannter Weise mittels einem Aequivalent einer Base, wie einem tert. Amin oder einer bei der folgenden Cyclisierung genannten Base, oder indem man die Verbindungen der Formel XI oder XII bereits als Phenolat dieser Base einsetzt. Man arbeitet in einem polaren, aprotischen Lösungsmittel oder Lösungsmittelgemisch wie zum Beispiel Dimethylformamid, N-Methylpyrrolidon, Hexamethylphosphorsäuretriamid, Tetramethylharnstoff oder vorzugsweise Dimethylsulfoxid.
- Die Cyclisierung bei Verfahren d) erfolgt ebenfalls in einem polaren, aprotischen Lösungsmittel, vorzugsweise in demselben, in dem auch die Veretherung stattfindet, bei im Vergleich zur Veretherung leicht erhöhten Temperaturen und in Gegenwart einer Base, wie z.B. quaternären Ammoniumbasen, Erdalkalihydroxiden, Alkaliamiden, Alkalihydriden, Alkalicarbonaten, vorzugsweise aber Alkalialkoholaten wie Kalium-t-butylat und Natriummethylat sowie insbesondere Alkalihydroxiden wie Natrium-, Kalium- und Lithiumhydroxid. Die basischen Kondensationsmittel werden in mindestens stöchiometrischen Mengen, vorzugsweise im Ueberschuss, eingesetzt. Vorteilhaft arbeitet man unter Luftsauerstoffausschluss und Inertgasatmosphäre.
- Unter Flüssigwaschmitteln sind bekannte und handelsübliche Waschmittel wie sie beispielsweise in der EP-A-167 205 oder US-4 507 219 oder GB 8712430 (=EP-A-293 040) beschrieben werden, zu verstehen.
- Der Gehalt an optischem Aufheller in den flüssigen Waschmitteln beträgt 0,01-2 %, insbesondere 0,01-1 %, besonders bevorzugt 0,03-0,3 %.
- Insbesondere enthalten die Flüssigwaschmittel neben den optischen Aufhellern 1 bis 60 % anionische, nichtionische, zwitterionische und gegebenenfalls kationische Tenside und 25 bis 65 % vorzugsweise 40 bis 55 % Wasser. Im einzelnen enthält das Waschmittel neben dem optischen Aufheller 3 bis 50 % vorzugsweise 15 bis 25 % anionische Tenside, 2 bis 30 % vorzugsweise 4 bis 15 % nichtionische Tenside, 3 bis 30 % vorzugsweise 5 bis 20 % gegebenenfalls ethoxylierte (C₁₀-C₁₄)-Fettsäuren wie Kaprin-, Laurin-, Myristin-, Kokusnuss- und Palmkernsäure sowie Mischungen davon, 1 bis 25 % vorzugsweise 1 bis 10 % Waschmittelaufbaustoffe sowie gegebenenfalls 1 bis 10% vorzugsweise 1 bis 5 % zwitterionische Tenside, 0,5 bis 3 % vorzugsweise 0,7 bis 2 % quaternäre Ammonium-, Amin- oder Aminoxid-Tenside, und 1 bis 10 % übliche Waschmittelzusätze wie zum Beispiel Enzyme, Enzymstabilisatoren, Antioxidantien, Konservierungs- und Desinfektionsmittel, Duft- und Farb- stoffe, Komplexbildner bzw. Sequestriermittel und Lösungsmittel.
- Brauchbare Tenside werden z.B. in der US-4 285 841, US-3 929 678, US-4 284 532 und GB-2 041 986 beschrieben. Insbesondere werden die in der EP-A-167 205 als bevorzugt bezeichneten Tenside eingesetzt. Vor allem verwendet man jedoch als anionische Tenside gegebenenfalls ethoxylierte C₁₀-C₁₈-Alkylsulfate z.B. in Form der Triethanolaminsalze, C₁₀-C₁₅-Alkylbenzolsulfonate oder Mischungen davon und als nichtionische Tenside Kondensationsprodukte aus einem Mol (C₁₀-C₁₅)-Fettalkohol mit 3 bis 8 Mol Ethylenoxid.
- Als Waschmittelaufbaustoffe kommen die in der US-4 321 165 und US-4 284 532 erwähnten vorzugsweise polycarboxylierte Verbindungen wie zum Beispiel Zitronensäure in Betracht.
- Gezielt sulfonierte Dibenzofuranylbiphenyle enthaltende flüssige Waschmittel können auch, wie z.B. in GB 8712430 (=EP-A-293 040) beschrieben, Bleichmittel enthalten. Als Bleichmittel wird vorzugsweise Perborat verwendet.
- Die folgenden Beispiele dienen zur Erläuterung der Erfindung; Teile bedeuten Gewichtsteile und Prozente Gewichtsprozente; der Fleckentest wird folgendermassen durchgeführt:
- a) Aufheller/Waschmittel-Formulierung: 0,1 % (100 % Aktivsubstanz) optischer Aufheller oder Aufhellergemisch werden in einem flüssigen Waschmittel gelöst. 0,6 g dieses Aufheller enthaltenden Waschmittels (A) wird mit 400 ml Wasser (10°-12° dH) bei einer Temperatur von 30°C verdünnt (Waschflotte B).
- b) Ein 20 g Stück gebleichtes Baumwollgewebe wird auf einem Spannrahmen befestigt.
- c) Auf eine vormarkierte, runde Fläche (5 cm Durchmesser) dieses Baumwollgewebes werden mit einer Pipette 0,6 ml der Waschmittellösung (A) gleichmässig aufgetragen, nach 30 Sekunden Einwirkzeit in die vorbereitete Waschflotte (B) gegeben und während 15 Minuten bei 30°C gewaschen. Anschliessend wird mit kaltem Wasser gespült und bei 70°C getrocknet.
- d) Der Unterschied des Weissgrades nach Ganz zwischen der Auftragsfläche und der Umgebung ist ein Mass für das sogenannte Spotting-Verhalten (Bildung von hellen Flecken) und wird bei einfacher Textillage mit einem RFC3-Photometer von Zeiss bestimmt.
