Description
Verfahren zur Herstellung basischer Monoazofarbstoffe Es wurde gefunden, daß man neuartige basische in Wasser lösliche Monoazofarbstoffe erhält, wenn man Farbstoffe der allgemeinen Formel worin R einen von wasserlöslichmachenden Gruppen freien Benzol- oder Naphthalinrest, R1 ein Wasserstoffatom oder eine Alkyl- oder Arylgruppe und R2 ein Wasserstoffatom oder eine Alkyl-, Aryl- oder Alkoxycarbonylgruppe darstellt, mittels eines Alkylierungsmittels in die entsprechenden Pyrazoliumfarbstoffe überführt. Die Diazokomponente kann durch Halogenatome sowie durch Alkyl-, Alkoxy-, Nitro- und Nitrilgruppen substituiert sein.Process for the preparation of basic monoazo dyes It has been found that novel basic water-soluble monoazo dyes are obtained by using dyes of the general formula where R is a benzene or naphthalene radical free of water-solubilizing groups, R1 is a hydrogen atom or an alkyl or aryl group and R2 is a hydrogen atom or an alkyl, aryl or alkoxycarbonyl group, converted into the corresponding pyrazolium dyes by means of an alkylating agent. The diazo component can be substituted by halogen atoms and by alkyl, alkoxy, nitro and nitrile groups.
Zur Herstellung des Ausgangsfarbstoffs kann die Kupplung in einem Medium von Natriumacetat-Essigsäure oder in alkalischem Medium erfolgen. Die erfindungsgemäße Umwandlung in quarternäre Ammoniumsalze erfolgt durch die Einwirkung eines Alkylierungsmittels, beispielsweise eines Dialkylsulfats, eines Alkylhalogenids oder eines Arylsulfonylesters auf den in einem inerten Lösungsmittel in Lösung befindlichen Farbstoff.To produce the starting dye, the coupling can be carried out in one Medium made of sodium acetate-acetic acid or in alkaline medium. The inventive Conversion into quaternary ammonium salts takes place through the action of an alkylating agent, for example a dialkyl sulfate, an alkyl halide or an aryl sulfonyl ester on the dye in solution in an inert solvent.
Der quarternäre Charakter der auf diese Weise erhaltenen Farbstoffe wird bestätigt durch den Umstand, daß dieselben in Wasser löslich sind, während die Ausgangsfarbstoffe in einem wässerig sauren Medium praktisch nicht löslich sind; ferner werden sie aus ihrer wässerigen Lösung durch den Zusatz einer Mineralbase, wie z. B. Natriumhydroxyd, nicht ausgefällt. Die erfindungsgemäßen Farbstoffe können durch die folgende allgemeine Formel dargestellt werden in welcher A ein Anion ist und R, R' und R2 die gleiche Bedeutung wie in der Formel (1) haben.The quaternary character of the dyes obtained in this way is confirmed by the fact that they are soluble in water, while the starting dyes are practically insoluble in an aqueous acidic medium; They are also removed from their aqueous solution by adding a mineral base, such as. B. sodium hydroxide, not precipitated. The dyes of the present invention can be represented by the following general formula in which A is an anion and R, R 'and R2 have the same meaning as in formula (1).
Die duarternisierten Farbstoffe von der Formel (11) ihrhcn die synthetischen Fasern auf der Basis von Polymeren und Mischpolymeren des Acrylnitrils in lebhaften Farbtönen von einem grünlichen Gelb bis zum Rot, die sehr gute Licht- und Naßechtheiten aufweisen. Die Farbstoffe besitzen obendrein die Eigenschaft, die Wolle nicht anzufärben.The dyestuff dyes of the formula (11) are synthetic ones Fibers based on polymers and copolymers of acrylonitrile in lively Color shades from a greenish yellow to red, the very good light and wet fastness properties exhibit. The dyes also have the property of not staining the wool.
Im Gegensatz zu dem Verfahren der deutschen Auslegeschrift 1040 152, in welchem eine Alkylierung des Pyrazolonrestes nicht erfolgt, führt das erfindungsgemäße Verfahren zu Pyrazoliumfarbstoffen. Diese haben beispielsweise den Vorteil, daß sie in Wasser löslich sind. Gegenüber den aus der französischen Patentschrift 1 145 751, Beispiel 7, bekannten Pyrazolonfarbstoffen besitzen die erfindungsgemäß hergestellten Farbstoffe den Vorteil einer deutlich höheren färberischen Kraft.In contrast to the process of German Auslegeschrift 1 040 152, in which an alkylation of the pyrazolone radical does not take place, the process according to the invention leads to pyrazolium dyes. These have the advantage, for example, that they are soluble in water. Compared with the pyrazolone dyes known from French patent specification 1,145,751, Example 7, the dyes prepared according to the invention have the advantage of a significantly higher dyeing power.
In den nachstehenden Beispielen sind die Teilmengen Gewichtsteile, wenn nichts Gegenteiliges angegeben ist. .In the examples below, the partial amounts are parts by weight, unless stated otherwise. .
Beispiel l 10 Gewichtsteile des Farbstoffs, welcher durch die Kupplung des Diazoderivats von Anilin mit 3-Methyl-5-pyrazolon erhalten worden ist, werden unter Rückfluß in 125 Teilen trockenen Chlorbenzols aufgelöst. Man rührt langsam 16 Teile Dimethylsulfat, mit 10 Teilen Chlorbenzol verdünnt, ein. Man läßt weitere 11/2 Stunden kochen und entfernt das Lösungsmittel mittels Wasserdampf: Die Farbstofllösung wird filtriert: nach dem Abkühlen wird der Farbstoff durch den Zusatz von Natriumehlorid und Zinkchlorid ausgefällt. Man filtriert und trocknet. Der Farbstoff färbt Polyacrylnitrilfasem in einem grünlichgelben Farbton an. Unter den gleichen Färbebedingungen wird die Wolle nicht angefärbt.Example l 10 parts by weight of the dye, which by the coupling of the diazo derivative of aniline with 3-methyl-5-pyrazolone dissolved under reflux in 125 parts of dry chlorobenzene. One stirs slowly 16 parts of dimethyl sulfate, diluted with 10 parts of chlorobenzene, a. One leaves more Boil for 11/2 hours and remove the solvent with steam: the dye solution is filtered: after cooling, the dye is replaced by the addition of sodium chloride and zinc chloride precipitated. Filter and dry. The dye stains polyacrylonitrile fibers in a greenish-yellow shade. Among the same The wool is not dyed under dyeing conditions.
