Description
Verfahren zur Herstellung eines Monoazofarbstoffes. Im Schweizer Patent Nr. 178818 und seinen Zusätzen sind wertvolle, chromierbare Monoazofarbstoffe beschrieben:, die durch Kupplung von 4-Nitro,-2-,aminophenol-6- sulfonsäure mit Phenolen, die in p-Stellung eine Alkylgruppe mit mindestens drei und höchstens fünf Kohlenstoffatomen besitzen, erhalten werden.
Es wurde nunmehr weiter gefunden, dass sehr wertvolle chromierbare Monoazofarb- stoffe entstehen, wenn man 4-Nitro-21-amino- phenol-6-sulfonsäure mit Phenolen der all gemeinen Formel
EMI0001.0019
worin X = Alkyl mit mindestens 3, höch stens aber 8 Kohlenstoffatomen oder Cyclo- alkyl, Y =Chlor oder Alkyl mit höchstens 8 Kohlenstoffatomen oder Cycloalkyl bedeu ten,
wobei die 5-Stellung gegebenenfalls durch Methyl substituiert sein kann, kuppelt. Phenolderivate entsprechend vorliegen dem Verfahren sind zum Beispiel 2',4-Di-tert. amylphenol, 2-tert. Amyl-4-tert. butylphenol, 2,4-Di-tert. butylphenol, 2-tert. Amyl-4- methylphenol, 2-Hegyl-4-chlorphenol,
2-Pro- pyl-4-tert. butylphenol, 2-Oetyl-4-methyl- phenbl, 2-tert. Amyl-4,5-dimethylphenol, 2- tert. Butyl-4-cyclohegylphenol u. a.
Die neuen Farbstoffe sind dunkle Pulver. Sie färben Wolle aus saurem Bade in orangen bis braunen Tönen, die nach allen bekannten Chromierungsmethoden sehr wert volle olivebraune bis braunolive Nuancen ergeben. Bemerkenswert gegenüber den Farbstoffen der oben erwähnten Patente ist die Verschiebung des Farbtones gegen olive, die Verbesserung der Pottingechtheit und zum Teil der Lichtechtheit,
überraschender weise bedingt durch die in 2-Stellung sich befindende höhere Alkyl- bezw. Cycloalkyl- gruppe, wobei besonders gute Effekte die tert. höheren Alkylgruppen zeigen. Die neuen Farbstoffe können auch in Substanz chromiert werden.
Gegenstand vorliegenden Patentes ist die Darstellung eines llonoazofarbstoffes, da durch gekennzeichnet, dass man dia.zotierte 4-Nitro-2-aminophenol-6-sulfonsäure mit 2- Isooctyl-4-tert. a.mylphenol kuppelt.
Der neue Farbstoff stellt ein dunkles Pulver dar, das sich in Wasser mit rot brauner, in Schwefelsäure mit brauner Farbe löst und Wolle nach einem Chromierverfah- ren in sehr echten olivebraunen Tönen färbt.
Beispiel: 23,4 Teile 4-Nitro-2-a.ininophenol-6-siil- fonsäure werden nach bekannten Methoden diazotiert. Der Überschuss -an @ineralsä,ure wird mit Bicarbonat abgestumpft.
-Die Di- azoniumlösung gibt man zu einer Emulsion von 27,6 Teilen 2-Isoocty 1-4-tert. ainyl- phenol, 6 Teilen Türkischrotöl in 200 Volum- teilen Wasser, die mit 6 Teilen Kalilauge 11l0 % ig und 6 Teilen Ammoniak versetzt ist. Nach beendeter Kupplung wird mit wenig Salz versetzt, filtriert und getrocknet.
Der Farbstoff bildet ein dunkles Pulver, das sich in Wasser rotbraun, in konzentrier ter Schwefelsäure braun löst. Er färbt Wolle clii-omiert, und zwar nach allen bekannten Methoden, in se lir eeliten olivebraunen Tönen.
Process for the preparation of a monoazo dye. Valuable, chromable monoazo dyes are described in Swiss patent no. 178818 and its additives: which, by coupling 4-nitro, -2-, aminophenol-6-sulfonic acid with phenols, have an alkyl group in the p position with at least three and at most five Have carbon atoms are obtained.
It has now also been found that very valuable chromable monoazo dyes are formed when 4-nitro-21-aminophenol-6-sulfonic acid is mixed with phenols of the general formula
EMI0001.0019
where X = alkyl with at least 3, but at most 8 carbon atoms or cycloalkyl, Y = chlorine or alkyl with at most 8 carbon atoms or cycloalkyl,
where the 5-position can optionally be substituted by methyl, couples. Phenol derivatives according to the process are, for example, 2 ', 4-di-tert. amylphenol, 2-tert. Amyl-4-tert. butylphenol, 2,4-di-tert. butylphenol, 2-tert. Amyl-4-methylphenol, 2-hegyl-4-chlorophenol,
2-propyl-4-tert. butylphenol, 2-ethyl-4-methylphenbl, 2-tert. Amyl-4,5-dimethylphenol, 2- tert. Butyl-4-cyclohegylphenol and the like a.
The new dyes are dark powders. They dye wool from an acid bath in orange to brown shades, which after all known chromizing methods result in very valuable olive-brown to brown-olive nuances. Noteworthy compared to the dyes of the above-mentioned patents is the shift in the shade towards olive, the improvement in potting fastness and, in some cases, light fastness,
Surprisingly, due to the higher alkyl respectively located in the 2-position. Cycloalkyl group, with particularly good effects the tert. show higher alkyl groups. The new dyes can also be chromed in substance.
The subject of the present patent is the representation of a llonoazo dye, characterized in that dia.zotierte 4-nitro-2-aminophenol-6-sulfonic acid with 2-isooctyl-4-tert. a.mylphenol coupling.
The new dye is a dark powder that dissolves in water with a red-brown color, in sulfuric acid with a brown color and colors wool in very genuine olive-brown tones using a chroming process.
Example: 23.4 parts of 4-nitro-2-a.ininophenol-6-silicic acid are diazotized by known methods. The excess of mineral acid is blunted with bicarbonate.
The diazonium solution is added to an emulsion of 27.6 parts of 2-isoocty 1-4-tert. ainyl phenol, 6 parts of Turkish red oil in 200 parts by volume of water to which 6 parts of 1110% potassium hydroxide solution and 6 parts of ammonia are added. After the coupling has ended, a little salt is added, the mixture is filtered and dried.
The dye forms a dark powder that dissolves red-brown in water and brown in concentrated sulfuric acid. He dyes wool in a cli-omed manner, using all known methods, in se lir eelite olive-brown tones.
