Description
Verfahren zur Herstellung neuer wasserlöslicher basischer Azofarbstoffe Es wurde gefunden, dass man zu wertvollen was serlöslichen, basischen Azofarbstoffen gelangt, die frei von sauren, wasserlöslichmachenden Gruppen, insbe sondere Sulfonsäure- oder Carbonsäuregruppen sind und der Formel A-N=N-B entsprechen, worin A den Rest eines diazotierten Amins und B den Rest einer.
Kupplungskomponente darstellen, wobei mindestens einer der Reste A oder B sich von einem Aminonaphthalin ableitet, welches am Naphthahnkern eine Gruppe der Formel
EMI0001.0012
aufweist, worin alk eine Alkylengruppe, Ml, R2 und R, Alkyl-, Aralkyl- oder Cycloalkylgruppen bedeuten, wobei R1, R2 und R3 zusammen mit dem Stickstoff atom einen heterocyclischen Ring bilden können,
und X ein Anion bedeutet, wenn man einen Azofarbstoff, dessen Diazo- und/oder Kupplungskomponente sich von einem Aminonaphthalin ableitet, das am Naphtha linkern eine Halogenacylgruppe aufweist, mit einem tertiären Amin der Formel
EMI0001.0029
umsetzt. Als tertiäre Amine kommen beispielsweise Trime- thylamin, Triäthylamin, Triäthanolamin, Dimethylcy- clohexylamin, N-Methylpiperidin oder Pyridin in Be tracht.
Die Umsetzung geschieht zweckmässig durch Erwärmen in einem Überschuss des Amins in An- oder Abwesenheit eines Lösungsmittels. Die halogenacyl- gruppenhaltigen Ausgangsfarbstoffe erhält man vorteil haft durch Kuppeln eines diazotierten Amins mit einer Kupplungskomponente, wobei mindestens eine der Komponenten ein Aminonaphthalin darstellt, welches am Naphthalinkern eine Halogenacylgruppe aufweist und worin, falls es als Kupplungskomponente dient,
die Aminogruppe beispielsweise durch eine oder zwei Alkylgruppen oder eine Phenylgruppe substituiert sein kann. Die Aminonaphthaline entsprechen vorzugsweise der Formel
EMI0001.0051
worin R1, R2 und R3 die angegebene Bedeutung haben und n die Zahl 1 oder 2 bedeutet. Diese Verbin dungen können erhalten werden durch Kondensation eines acylierten oder dialkylierten Aminonaphthalins, z.
B. von 1-Acetylaminonaphthalin, 2-Acetylaminonaphthalin, N-Acetyl-l-äthylaminonaphthalin, N-Acetyl-l-methylaminonaphthalin, N-Acetyl-l-phenylaminonaphthalin, N-Acetyl-2-äthylaminonaphthalin, N-Acetyl-2-phenylaminonaphthalin oder 2-Diäthylaminonaphthalin, mit Chloracetyl- oder Chlorpropionylchlorid in Ge genwart von Aluminiumchlorid.
Verwendet man das Aminonaphthalin als Diazokomponente, so kommen beliebige Kupplungskomponenten in Betracht, bei spielsweise solche der Benzol- oder Naphthalinreihe oder der Reihe der heterocyclischen Kupplungskompo nenten.
Von den Kupplungskomponenten der Benzol reihe seien insbesondere die Aminobenzole genannt, beispielsweise Dimethylanilin, Diäthylanilin, N-Äthyl- N-cyanäthylanilin, Di-(cyanäthyl)-anilin, Di-(hydroxy- äthyl)-anilin, Di-(cyanäthoxyäthoxy)-anilin,

Aus der Reihe der heterocyclischen Kupplungskomponenten seien bei spielsweise die Indole, wie 2-Methylindol, 2,5-Dimethylindol, 2,4-Dimethyl-7-methoxyindol, 2-Methyl-5-äthoxyindol, 2-Methyl-5- oder -6-chlorindol, 1,2-Dimethylindol, 1-Methyl-2-phenylindol, 2-1VIethyl-5-nitroindol, 2-Methyl-5-cyanindol, 2-Methyl-chlorindol, 2-Methyl-5,
7-dichlorindol oder 2-Phenylindol, 1-Cyanäthyl-2,6-dimethylindolin, ferner Pyrazole wie z. B. das 1-Phenyl-5-aminopyrazol oder 3-Methyl-pyrazolon-5- oder das 1-Phenyl-3-methyl-pyrazolon-5, Chinoline, wie das 1-Methyl-4-hydroxychinolin-2- oder Pyrimidine, wie Barbitursäure genannt.
Werden die erwähnten Aminonaphthaline als Kupplungskomponenten verwendet, so kommen als Diazokomponenten beliebige diazotierbare aromatische oder heterocyclische Amine in Betracht. Aus der Reihe der aromatischen Amine seien beispielsweise Amino- naphthaline, insbesondere aber die Aminobenzole ge nannt.
Diese entsprechen vorzugsweise der Formel
EMI0002.0044
worin X, ein Wasserstoff- oder Halogenatom, eine Cyan-, Carbalkoxy-, Alkylsulfonyl-, eine gegebenen falls substituierte Sulfonamid- oder Phenylazo- oder eine Nitrogruppe, Y1 ein Wasserstoff- oder Halogen atom, eine Nitro-, Alkyl-, Alkoxy-, Trifluormethyl-, Carbalkoxy- oder Cyangruppe, Z1 ein Wasserstoff- oder Halogenatom bedeuten,

Aus der Reihe der heterocyclischen Diazokompo- neDten seien beispielsweise die 2-Aminothiazole, vor zugsweise 2-Amino-5-nitro-thiazol, oder insbesondere 2-Aminobenzthiazole genannt, beispielsweise 2-Aminothiazol, 2-Amino-5-nitrothiazol, 2-Amino-5-cyanthiazol, 2-Amino-4-methyl-5-nitrothiazol, 2-Amino-4-methylthiazol, 2-Amino-4-phenylthiazol, 2-Amino-4-(4'-chlor)-phenylthiazol,
2-Amino-4-(4'-nitro)-plhenylthiazol, 2-Aminobenzthiazol , 2-Amino-6-methylbenzthiazol, 2-Amino-6-methoxybenzthiazol, 2-Amino-6-chlorbenzthiazol, 2-Amino-6-nitrobenzthiazol, ferner 2-Amino-1,3,4-thiadiazol, 2-Amino-1,3,5-thiadiazol, 2-Amino-4-phenyl-1,3,5-thiadiazol.
Die Diazotierung der erwähnten Diazokomponen- ten kann nach an sich bekannten Methoden, z. B. mit Hilfe von Mineralsäure, insbesondere Salzsäure, und Natriumnitrit erfolgen.
Die Kupplung kann ebenfalls in an sich bekannter Weise, z. B. in saurem bis alkalischem Mittel, gegebe nenfalls in Gegenwart von Natriumacetat oder ähn lichen, die Kupplungsgeschwindigkeit beeinflussenden Puffersubstanzen oder Katalysatoren wie z. B. Pyridin, resp. dessen Salzen, vorgenommen werden.
Die Reinigung der Farbstoffsalze erfolgt zweckmäs- sig durch Auflösen in Wasser, wobei allenfalls nicht umgesetzter Ausgangsfarbstoff als unlöslicher Rück stand abfiltriert werden kann. Aus der wässerigen Lösung kann durch Zugabe von wasserlöslichen Sal- zen, beispielsweise Natriumchlorid, der Farbstoff wie der abgeschieden werden.
Die verfahrensgemäss erhaltenen Farbstoffe enthal ten als Anion vorzugsweise den Rest einer starken Säure, beispielsweise der Schwefelsäure, oder deren Halbester, oder einer Arylsulfonsäure oder ein Halogen ion. Die erwähnten, verfahrensgemäss in das Farb- stoffmolekül eingeführten Anionen können auch durch Anionen anderer anorganischer Säuren, beispielsweise der Phosphorsäure, der Schwefelsäure, oder organi scher Säuren, wie z.
B. der Ameisensäure oder Essig säure, der Chloressigsäure, der Oxalsäure, der Milch säure oder der Weinsäure ersetzt werden; in gewissen Fällen können auch die freien Basen verwendet wer den. Die Farbstoffsalze können auch in Form von Doppelsalzen, beispielsweise mit Halogeniden der Ele mente der zweiten Gruppe des periodischen Systems, insbesondere Zink- oder Cadmiumchlorid, verwendet werden.
Die erfindungsgemäss erhaltenen Farbstoffsalze eignen sich zum Färben und Bedrucken der verschie densten Materialien, beispielsweise tannierter Cellulo- sefasern, Seide, Haare, Leder oder vollsynthetischer Fasern, insbesondere Polyacrylnitril oder Polyvinyl- idencyanid (Darvan); Die auf ' diesen; Fasern erhaltenen. Färbungen zeichnen sich durch gute Lichtechtheit aus.
Auch besitzen die Farbstoffe eine gute Wollreserve, was sie besonders für das Färben von Mischgeweben aus Polyacrylnitril geeignet macht. Bemerkenswert ist auch die gute Carbonisierechtheit der erhaltenen Fär bungen.
Gegenstand der vorliegenden Erfindung sind auch die den gemäss Verfahren c) hergestellten quaternisier- ten Farbstoffe entsprechenden Ausgangsverbindungen mit einem ternären Stickstoffatom, die sich vor allem as Dispersionsfarbstoffe zur Färbung von Cellulose- aeetatfasern und insbesondere von vollsynthetischen Polyesterfasern, z. B. Polyäthylenterephthalatfasern, eignen.
Im nachfolgenden Beispiel bedeuten die Teile, sofern nichts anderes angegeben wird, Gewichtsteile, die Prozente Gewichtsprozente, und die Temperaturen sind in Celsiusgraden angegeben. <I>Beispiel</I> 4,14 Teile 2,6-Dichlor-4-nitroanilin werden in Nitrosylschwefelsäure diazotiert und die erhaltene Di- azoverbindung in eine eisgekühlte salzsaure Lösung von 4,4 Teilen eines Gemisches von 2-Amino-6- resp. -8-chloracetylnaphthalin eingetropft.
Anschliessend wird durch langsame Zugabe von wässeriger Natrium- acetatlösung kongoneutral gestellt, der wasserlösliche Farbstoff abfiltriert, mit Wasser gut ausgewaschen und getrocknet.
4,37 Teile des so erhaltenen, eine Chloracetyl- gruppe tragenden Farbstoffes werden mit 10 Teilen Pyridin 1 Stunde bei 120 gerührt, bis eine Probe voll kommen wasserlöslich ist. Man verdünnt mit 100 Tei len Wasser und fällt den Farbstoff mit 10 Teilen Koch salz aus. Er färbt Polyacrylnitrilfasern in echten rot braunen Tönen.
Zu Farbstoffen mit ähnlichen färberischen Eigen schaften gelangt man, wenn man anstelle von Pyridin gleiche Mengen N-Methylpiperidin oder N-Methylmor- pholin verwendet.
In analoger Weise erhält man durch Kupplung der Diazoverbindung des in nachfolgender Tabelle in Kolonne 1I aufgeführten Amins mit dem Gemisch von 2-Amino-6- resp. -8-chloracetylnaphthalin und an- schliessender Umsetzung mit der in Kolonne IH ange gebenen tertiären Base basische Farbstoffe der in Kolonne IV genannten Nuance.

implements. Suitable tertiary amines are, for example, trimethylamine, triethylamine, triethanolamine, dimethylcyclohexylamine, N-methylpiperidine or pyridine.
The reaction is conveniently carried out by heating in an excess of the amine in the presence or absence of a solvent. The starting dyes containing haloacyl groups are advantageously obtained by coupling a diazotized amine with a coupling component, at least one of the components being an aminonaphthalene which has a haloacyl group on the naphthalene nucleus and in which, if it is used as a coupling component,
the amino group can be substituted, for example, by one or two alkyl groups or a phenyl group. The aminonaphthalenes preferably correspond to the formula
