Die Aufarbeitung des Reaktorgemisches erfolgt in bekannter Weise z.B. durch Zusatz von Methanol oder Äthanol und Abtrennen der ausgefallenen Produkte. Die so erhaltenen Produktgemische lassen sich durch HPLC (High pressure liquid chromatography) analysieren und charakterisieren.The claimed process can be carried out, for example, by placing the proton acceptor in the solvent and adding a solution of the reaction components 9-11 in the solvent, but it is also possible to add the compounds 9-11 and adding them to the proteone acceptors. A further embodiment consists in presenting the compounds 9-11, in which X or Q represents a group of the formula 12a-d, then first adding the proton acceptor and then the aldehyde component. The reaction generally takes place with intense heat so that cooling may be necessary. The The reactor mixture is worked up in a known manner, for example by adding methanol or ethanol and separating off the precipitated products. The product mixtures obtained in this way can be analyzed and characterized by HPLC (high pressure liquid chromatography).
Die Ausgangsverbindungen der Formeln 9 - 11 sind bekannt bzw. können nach bekannten Verfahren hergestellt werden.The starting compounds of the formulas 9-11 are known or can be prepared by known processes.
Von den Verbindungen unter den Formeln 4 bis 8 sind in den erfindungsgemäßen Gemischen die Verbindungen der folgenden Formeln bevorzugt:
bedeutet, wobei R14, Alkyl, Chloralkyl, Alkoxyalkyl, Hydroxyalkyl oder eine Gruppe der Formel -(CH2CH2O)n-R bedeutet, wobei n 2 oder 3 und R Wasserstoff oder Alkyl ist, R15 Phenyl bedeutet, das durch ein oder zwei Chloratome, ein oder zwei Alkyl-, Alkoxyalkylgruppen, eine Phenyl-, Cyano-, Carbonsäure-, Carboalkoxy-, Carbonsäureamid-, Sul- fonsäure-, Sulfonsäureamid-, oder Sulfonsäurealkylestergruppe substituiert sein kann, R23 Cyano oder Carboalkoxy und R22 Alkyl bedeutet.
Ganz besonders bevorzugt sind von den Verbindungen unter der Formel 4 die Verbindungen der Formel
und R14" Alkyl oder Methoxyäthyl bedeutet. Von besonderer Wichtigkeit sind die folgenden Verbindungen unter der Formel 4:
and R 14 " denotes alkyl or methoxyethyl. Of particular importance are the following compounds under the formula 4:
Bevorzugt ist ein Mischungsverhältnis von 5 bis 50 Gew.-% für die Komponente A und 95 bis 50 Gew.-% eines oder mehrerer Aufhellern der Formeln 4 bis 8 (Komponente B).A mixing ratio of 5 to 50% by weight for component A and 95 to 50% by weight of one or more brighteners of the formulas 4 to 8 (component B) is preferred.
Das optimale Mischungsverhältnis aller Verbindungen hängt im Einzelfall von der Struktur der jeweiligen Verbindungen ab und läßt sich durch einfache Vorversuche unschwer ermitteln.The optimal mixing ratio of all compounds depends on the structure of the respective compounds in individual cases and can easily be determined by simple preliminary tests.
Wie bei optischen Aufhellern üblich, werden die einzelnen Komponenten surch Dispergierung in einem flüssigen Medium z.B. Wasser in die Hancelsform gebracht. Man kann cabei die einzelnen Komponenten jede für sich dispergieren und dann die Dispersionen zusammen geben. Man kann aber auch die Einzelkomponenten in Substanz miteinander mischen und dann gemeinsam dispergieren. Dieser Dispergiervorgang geschieht in üblicher Weise in Kugelmühlen, Kolloidmünlen, Perlmühlen oder Dispersionsknetern. Die erfindungsgemäßen Mischungen eignen sich besonders zum Aufhellen von Textilmaterial aus linearen Polyestern, Polyamiden und Acetylcellulose. Man kann diese Mischungen aber auch mit gutem Ergebnis bei Mischgeweben verwenden, die aus linearen Polyestern und anderen synthetischen oder natürlichen Faserstoffen namentlich hydroxylgruppenhaltigen Fasern, insbesondere Baumwolle bestehen. Die Applikation dieser Mischungen geschieht dabei unter den für die Anwendung von optischen Aufhellern üblichen Bedingungen so beispielsweise nach dem Ausziehverfahren bei 90°C bis 130°C mit oder ohne Zusatz von Beschleunigern (Carriern) oder nach dem Thermosolverfahren. Die in Wasser unlöslichen Aufheller und die erfindungsgemäßen Mischungen können aucn in organischen Lösemitteln z.B. Perchloräthylen, fluorierten Kohlenwasserstoffen gelöst zum Einsatz kommen. Dabei kann das Textilmaterial im Ausziehverfahren mit der Lösemittelflotte, welche den optischen Aufheller gelöst enthält, behandelt werden, oder man imprägniert, pflatscht, sprüht das Textilgut mit der aufhellerhaltigen Lösemittelflotte und trocknet anschließend bei Temperaturen von 120 - 220°C, wobei der optische Aufheller dabei restlos in der Faser fixiert wird. Man erhält dabei eine hervorragend aufgehellte Ware mit ausgezeichneter Lichtbeständigkeit, sowie Beständigkeit gegenüber Oxidations- und Reduktionsmitteln. Diese erfindungsgemäßen Mischungen weisen im Vergleich zu den Mischungen des japanischen Patents Sho 50(1975)-25 877 höhere Weißgrade auf; sie ergeben ferner auch bereits bei niedrigen Thermosoliertemperaturen von z. B. 150°C hervorragende Weißgrade.As is usual with optical brighteners, the individual Components are brought into the Hancels form by dispersion in a liquid medium, for example water. The individual components can be dispersed individually and then the dispersions can be added together. However, the individual components can also be mixed together in bulk and then dispersed together. This dispersion process takes place in the usual way in ball mills, colloid mills, bead mills or dispersion kneaders. The mixtures according to the invention are particularly suitable for lightening textile material made from linear polyesters, polyamides and acetyl cellulose. However, these mixtures can also be used with good results in mixed fabrics which consist of linear polyesters and other synthetic or natural fiber materials, in particular fibers containing hydroxyl groups, in particular cotton. These mixtures are applied under the conditions customary for the use of optical brighteners, for example using the exhaust process at 90 ° C. to 130 ° C. with or without addition of accelerators (carriers) or using the thermosol process. The water-insoluble brighteners and the mixtures according to the invention can also be used in solution in organic solvents, for example perchlorethylene, fluorinated hydrocarbons. The textile material can be treated in the exhaust process with the solvent liquor, which contains the optical brightener, or one can impregnate, splash, spray the textile material with the brightener-containing solvent liquor and then dry at temperatures of 120 - 220 ° C, whereby the optical brightener is completely fixed in the fiber. The result is an excellently lightened product with excellent lightfastness and resistance to oxidizing and reducing agents. These mixtures according to the invention have higher degrees of whiteness than the mixtures of the Japanese patent Sho 50 (1975) -25,877; they also result even at low thermal insulation temperatures of z. B. 150 ° C excellent whiteness.
Die folgenden Tabellen-Beispiele illustrieren die Erfindung. Das angewandte Applikationsverfahren soll hier beispielgebend geschildert werden:
- Gewebeabschnitte aus Polyester-Stapelfasern werden gewaschen, getrocknet und auf einen Foulard mit wäßrigen Dispersionen imprägniert, die entweder den reinen optischen Aufheller der Formeln 4 bis 8 (Komponente B) mit einer Einsatzmenge von 0,08 Gew.-% oder ein Gemisch aus 0,064 Gew.-%, 0,04 Gew.- % bzw. 0,016 Gew.-% der Komponente A mit 0,016, 0,04 bzw. 0,064 Gew.-% der Aufheller der Komponente B enthalten. Als Komponente A wurde in allen Beispielen ein Gemisch aus 1,5 Gew.-Teilen 1,4-Bis-(4'-cyano-styryl)-benzol, 1,5 Gew.-Teilen 1,4-Bis-(2'-cyano-styryl)-benzol und 7-Gew.-Teilen 1-(2-Cyano-styryl)-4-(4'-cyano-styryl)-benzol eingesetzt.
- Fabric sections made of polyester staple fibers are washed, dried and impregnated onto a foulard with aqueous dispersions which either contain the pure optical brightener of the formulas 4 to 8 (component B) with an amount of 0.08% by weight or a mixture of 0.064% by weight .-%, 0.04% by weight or 0.016% by weight of component A with 0.016, 0.04 or 0.064% by weight of the brightener of component B. In all examples, component A was a mixture of 1.5 parts by weight of 1,4-bis (4'-cyano-styryl) benzene, 1.5 parts by weight of 1,4-bis- (2 ' -cyano-styryl) -benzene and 7 parts by weight of 1- (2-cyano-styryl) -4- (4'-cyano-styryl) -benzene.
Das Material wird mit einem Foulard zwischen Rollen so abgequetscht, daß sich eine Feuchtigkeitsaufnahme von ca. 80 % ergibt. Das entspricht einer Aufnahme an optischen Aufhellern auf die Ware von 0,064 %.. Das so geklotzte Material wurde anschließend auf einem Spannrahmen 30 Sek. bei 170° (Tabelle I) bzw. 210° (Tabelle II) thermosoliert. Dabei wurden die jeweils angegebenen Weißgrade nach Ganz erhalten. Die Weißgrade wurden mit einem Remissionsspektralphotometer Typ DMC-25 gemessen. (Firma Carl Zeiss, Oberkochen.
