Description
Verfahren <B>zur Herstellung</B> eines metallhaltigen Azofarbstoffes. Es wurde gefunden, dass man zu einem gelangt, wenn man auf den Monoazofarbstoff neuen, wertvollen metallhaltigen Azofarbstoff der Formel
EMI0001.0008
chromabgebende Mittel derart einwirken lässt, dass ein chromhaltiger Azofarbstoff entsteht, der zwei Monoazofarbstoffmoleküle an ein Chromatom komplex gebunden enthält.
Der neue Farbstoff bildet ein braunes Pul ver, das sieh in Wasser mit oranger Farbe löst und Wolle aus neutralem bis essigsaurem Bade in orangen Tönen färbt.
Der als Ausgangsstoff dienende, der oben stehenden Formel entsprechende Monoazofarb- stoff kann durch Kupplung des 1-(3'-Chlor- phenyl)-3-methyl-5-pyrazolons mit nach an sich bekannten Methoden, z. B. mittels Salz säure und Natriumnitrit, diazotier tem 2-Amino- 1-oxybenzol-4-sulfonsäureamid hergestellt wer den.
Die Behandlung mit den chromabgeben den Mitteln erfolgt, wie bereits erwähnt, in der Weise, dass ein chromhaltiger Farbstoff entsteht, der zwei Monoazofarbstoffmoleküle an ein Atom Chrom komplex gebunden ent hält. Demgemäss führt man die Chromierung zweekmä.ssig mit solchen chromabgebenden Mitteln und nach solchen Methoden durch, welche erfahrungsgemäss komplexe Chromver bindungen dieser Zusammensetzung liefern.
Es empfiehlt sich im allgemeinen, auf ein Molekül eines Farbstoffes weniger als ein Atom Chrom zu verwenden und/oder die Chromierung in schwach saurem bis alkali schem Medium auszuführen. Demzufolge sind auch diejenigen Chromverbindungen, die in alkalischem Medium beständig sind, für die Durchführung des Verfahrens besonders gut geeignet, wie z. B. solche Chromverbindungen aliphatischer 0xycarbonsäuren oder vorzugs weise aromatischer o-Oxycarbonsäuren, welche das Chrom in komplexer Bindung enthalten.
Die Metallisierung geschieht mit Vorteil in der Wärme, offen oder unter Druck, z. B. bei Siedetemperatur des Reaktionsgemisches, ge gebenenfalls in Anwesenheit geeigneter Zu sätze, z. B. in Anwesenheit von Salzen orga nischer Säuren, von Basen, organischen Lö sungsmitteln oder weiteren die Komplexbil dung fördernden Mitteln.
<I>Beispiel:</I> 18,8 Teile 2 ,Amino-l-oxybenzol-4-sulfon- säureamid werden in 50 Teilen Wasser und 14 Teilen 30 0]o iger Salzsäure gelöst und bei 0 bis 5 mit einer wässerigen Lösung von 6,9 Teilen Natriumnitrit diazotiert. Die mit Na- triumcarbonat neutralisierte Diazosuspension wird bei 1.0 bis 12 in eine Lösung aus 21 Tei len 1-(3'-Chlorphenyl)-3-methyl-5-pyrazolon,
50 Teilen Wasser und 14,0 Teilen 30%iger Na- triumhyAroxydlösLzng eingegossen. Die Kupp lung verläuft sehr rasch. Der Farbstoff wird durch Hinzufügen von Natriumchlorid voll ständig abgeschieden.
Die durch Abfiltrieren gewonnene Farbstoffpaste wird in 250 Teilen Wasser verrührt und mit 120 Teilen einer Lösung von chromsalicylsaurem Natrium/Ka- lium mit einem Chromgehalt von 2,6% sowie 6,7 Teilen 30%iger Natriumhydroxydlösung versetzt.
Das Ganze wird während 3 Stunden am Rüekfluss gekocht. Nach dieser Zeit ist die Chromierung beendet. Der chromhaltige Farb stoff wird durch Eindampfen des Reaktions gemisches im Vakuum isoliert.
Process <B> for the production </B> of a metal-containing azo dye. It has been found that one arrives at a new, valuable metal-containing azo dye of the formula ## STR3 ## if we look at the monoazo dye
EMI0001.0008
lets chromium-releasing agents act in such a way that a chromium-containing azo dye is formed which contains two monoazo dye molecules bound to a chromium atom in a complex.
The new dye forms a brown powder that dissolves in water with an orange color and dyes wool from neutral to acetic acid baths in orange tones.
The monoazo dye used as the starting material and corresponding to the above formula can be prepared by coupling the 1- (3'-chlorophenyl) -3-methyl-5-pyrazolone using methods known per se, eg. B. by means of hydrochloric acid and sodium nitrite, diazotized system 2-amino-1-oxybenzene-4-sulfonic acid amide produced who the.
The treatment with the chromium-releasing agents takes place, as already mentioned, in such a way that a chromium-containing dye is created which contains two monoazo dye molecules bound to one atom of chromium in a complex. Accordingly, the chromium plating is carried out in two ways with such chromium-releasing agents and by methods which, experience has shown, provide complex chromium compounds of this composition.
It is generally advisable to use less than one atom of chromium on a molecule of a dye and / or to carry out the chromation in a weakly acidic to alkaline medium. Accordingly, those chromium compounds that are stable in an alkaline medium are particularly well suited for carrying out the process, such as. B. those chromium compounds of aliphatic oxycarboxylic acids or preferably, aromatic o-oxycarboxylic acids, which contain the chromium in complex bonds.
The metallization takes place with advantage in the heat, open or under pressure, z. B. at the boiling point of the reaction mixture, ge where appropriate in the presence of suitable additives to, for. B. in the presence of salts of organic acids, bases, organic solvents or other means that promote the complex formation.
<I> Example: </I> 18.8 parts of 2-amino-1-oxybenzene-4-sulfonic acid amide are dissolved in 50 parts of water and 14 parts of 30% hydrochloric acid and, at 0 to 5, with an aqueous solution diazotized by 6.9 parts of sodium nitrite. The diazo suspension neutralized with sodium carbonate is at 1.0 to 12 in a solution of 21 parts 1- (3'-chlorophenyl) -3-methyl-5-pyrazolone,
50 parts of water and 14.0 parts of 30% sodium hydroxide solution are poured in. The coupling is very quick. The dye is completely deposited by adding sodium chloride.
The dye paste obtained by filtering off is stirred in 250 parts of water and mixed with 120 parts of a solution of chromium salicylic acid sodium / potassium with a chromium content of 2.6% and 6.7 parts of 30% sodium hydroxide solution.
The whole thing is boiled for 3 hours on the Rüek river. After this time, the chroming is finished. The chromium-containing dye is isolated by evaporating the reaction mixture in vacuo.
