Description

Die vorliegende Erfindung betrifft neue flüssige Waschmittel enthaltend gezielt disulfonierte Dibenzfuranylbiphenyle als optische Aufheller deren Herstellung und deren Verwendung.The present invention relates to new liquid detergents containing targeted disulfonated dibenzfuranylbiphenyls as optical brighteners, their preparation and their use.

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.The use of optical brighteners in liquid detergents is known. They soak on the items to be washed during treatment and, due to their special light absorption / emission properties, lead to an elimination of the yellowish tones or an improvement in the degree of whiteness.

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. In der EP-A-167 205 wird zur Lösung dieses Problems vorgeschlagen, monosulfonierte Stilbentriazolyl-, -triazin- oder Distyrylbiphenyl-Aufheller in anionischen Flüssigwasch­mitteln zu verwenden.This effect is also responsible for the appearance of light spots when textile fabrics e.g. comes into direct contact with the liquid detergent during pretreatment. To solve this problem, EP-A-167 205 proposes to use monosulfonated stilbene triazolyl, triazine or distyrylbiphenyl brighteners in anionic liquid detergents.

Ueberraschenderweise kann die Bildung heller Flecken, bei ausgezeichneter Aufhellwirkung und sehr gutem Lagerverhalten des flüssigen Waschmittels, auch durch optische Aufheller der Formel

verhindert werden.Surprisingly, the formation of light spots, with an excellent lightening effect and very good storage behavior of the liquid detergent, can also be achieved by optical brighteners of the formula

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.The starting compounds of the formulas (X), (XI) and (XII) are known and can be prepared by known methods.

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) z.B. Verbindungen der Formel (III) und (V) hergestellt. SO₃/Basen-Komplexe sind bekannt und können nach bekannten Methoden hergestellt werden (E.E. Gilbert, E.P. Jones, Ind. Enging.

The stability of these addition compounds is decisive for the degree of sulfonation. So when using 2 to 6, especially 3 to 5 moles of SO₃ / pyridine complex (based on the SO₃ content) per mole of the compound of formula (X), for example compounds of formula (III) and (V). SO₃ / base complexes are known and can be prepared by known methods (EE Gilbert, EP Jones, Ind. Enging. Chem. 49, No. 9, Part II, pp. 1553 ff (1957); Beilstein 20, III / IV , 2232).

Amine or a base mentioned in the following cyclization, or by already using the compounds of the formula XI or XII as the phenolate of this base. The process is carried out in a polar, aprotic solvent or solvent mixture, such as, for example, dimethylformamide, N-methylpyrrolidone, hexamethylphosphoric triamide, tetramethylurea or preferably dimethyl sulfoxide.

Die basischen Kondensationsmittel werden in mindestens stöchiometrischen Mengen, vorzugsweise im Ueberschuss, eingesetzt. Vorteilhaft arbeitet man unter Luftsauerstoffausschluss und Inertgasatmosphäre.The cyclization in process d) likewise takes place in a polar, aprotic solvent, preferably in the same one in which the etherification also takes place, at slightly elevated temperatures compared to the etherification and in the presence of a base, such as quaternary ammonium bases, alkaline earth metal hydroxides, alkali amides, alkali metal hydrides , Alkali metal carbonates, but preferably alkali metal alcoholates such as potassium t-butoxide and sodium methylate, and in particular alkali metal hydroxides such as sodium, potassium and lithium hydroxide.

Nos. 4,321,165 and 4,284,532, such as citric acid.

Gezielt sulfonierte Dibenzofuranylbiphenyle enthaltende flüssige Wasch­mittel können auch, wie z.B. in GB 8712430 beschrieben, Bleichmittel enthalten. Als Bleichmittel wird vorzugsweise Perborat verwendet.Targeted liquid detergents containing sulfonated dibenzofuranylbiphenyls can also be used e.g. in GB 8712430, contain bleach. Perborate is preferably used as the bleaching agent.

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.
The following examples serve to illustrate the invention; Parts mean parts by weight and percentages percentages by weight; The stain test is carried out as follows:
  • a) Brightener / detergent formulation:
    0.1% (100% active substance) optical brightener or brightener mixture are dissolved in a liquid detergent. 0.6 g of this detergent (A) containing brightener is diluted with 400 ml of water (10 ° -12 ° dH) at a temperature of 30 ° C (wash liquor B).
  • b) A 20 g piece of bleached cotton fabric is attached to a tenter.
  • c) 0.6 ml of the detergent solution (A) are evenly applied to a pre-marked, round surface (5 cm in diameter) of this cotton fabric, added to the prepared wash liquor (B) after 30 seconds of exposure and for 15 minutes at 30 ° C washed. It is then rinsed with cold water and dried at 70 ° C.
  • d) The difference in whiteness according to Ganz between the application area and the surroundings is a measure of the so-called spotting behavior (formation of light spots) and is determined with a simple textile layer using an RFC3 photometer from Zeiss.
