Description
Verfahren zur Herstellung eines metallhaltigen Azofarbstoffes. Es wurde gefunden, dass man zu einem neuen, wertvollen metallhaltigen Azofarbstoff gelangt, wenn man auf den Monoazofarbstoff der Formel
EMI0001.0006
chromabgebende Mittel derart einwirken lässt, dass ein chromhaltiger Azofarbstoff entsteht, der zwei Monoazofarbstoffmoleküle an ein Chromatom komplex gebunden enthält.
Der neue Farbstoff bildet ein braunrotes Pulver, 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-Phenyl-3- methyl-5-pyrazolons mit nach an sich bekann ten Methoden, z. B. mittels Salzsäure und Na triumnitrit dianotiertem 2-Amino-l-oxybenzol- -1-sulfonsäuredimethylamid hergestellt werden.
Die Behandlung mit den chromabgebenden Mitteln erfolgt, wie bereits erwähnt, in der Weise, dass ein chromhaltiger Farbstoff ent steht, der zwei Monoazofarbstoffmoleküle an ein Atom Chrom komplex gebunden enthält. Demgemäss führt man die Chromierung zweck- mässig mit solchen chromabgebenden Mitteln und nach solchen Methoden durch, welche er fahrungsgemäss komplexe Chromverbindim.gen dieser Zusammensetzung liefern.
Es empfiehlt sich im allgemeinen, auf ein Molekül eines Farbstoffes weniger als ein Atom Chrom zu verwenden undjoder die Ohromierung in schwach saurem bis alkalischem Mediiun aus- zuführen. Demzufolge sind auch diejenigen Chromverbindungen, die in alkalischem Me dium beständig sind, für die Durchführung des Verfahrens besonders gut geeignet wie z.
B. solche Chromverbindungen aliphatischer Oxycarbonsäuren oder vorzugsweise aroma tischer o-Oxycarbonsäuren, welche das Chrom in komplexer Bindung enthalten. Die Me- tallisierung 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 organischer Säuren, von Basen, organischen Lösungsmitteln oder weiteren die Komplex bildung fördernden Mitteln.
Beispiel: 21,6 Teile 2-Amino-l-oxybenzol-4-sulfon- säuredimethylamid werden in 50 Teilen @Nras- ser und 14 Teilen 30%iger Salzsäure gelöst und bei 0 bis 5 mit einer wässrigen Lösung von 6,9 Teilen Natriumnitrit diazotiert. Die mit Natriumcarbonat neutralisierte Diazosus- pension wird bei 10 bis 12 in eine Lösung aus 18,3 Teilen 1-Phenyl-3-methyl-5-pyrazolon, 50 Teilen Wasser und 14,
0 Teilen 30 % iger Natriumhydroxy dlösung eingegossen. Die Kupplung verläuft sehr rasch. Der Farbstoff wird durch Hinzufügen von Natriumchlor id vollständig abgeschieden.
Die durch Abfiltrie- ren gewonnene Farbstoffpaste wird in 250 Teilen Wasser verrührt und mit 120 Teilen einer Lösung von chromsalieylsaurem Na trium/Kalium mit einem Chromgehalt von <B>2,6%</B> sowie 6,7 Teilen 30%iger Natrium- hydroxy dlösung versetzt. Das Ganze wird 3 Stunden am Rückfluss gekocht. Nach dieser Zeit ist die Chromierung beendet. Der chrom- haltige Farbstoff wird durch Eindampfen des Reaktionsgemisches im Vakuum isoliert.
Process for the preparation of a metal-containing azo dye. It has been found that a new, valuable metal-containing azo dye is obtained by using the monoazo dye of the formula
EMI0001.0006
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-red powder, which dissolves in water with an orange color and dyes wool from neutral to acetic acid baths in orange tones.
The monoazo dye used as starting material and corresponding to the above formula can be prepared by coupling the 1-phenyl-3-methyl-5-pyrazolone with methods known per se, e.g. B. by means of hydrochloric acid and sodium nitrite dianotized 2-amino-1-oxybenzene -1-sulfonic acid dimethylamide can be produced.
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 chromizing is expediently carried out with such chromium-releasing agents and by such methods which, according to experience, provide complex chromium compounds of this composition.
It is generally advisable to use less than one atom of chromium per molecule of a dye and / or to carry out the odorization in a weakly acidic to alkaline medium. As a result, those chromium compounds that are stable in alkaline Me are particularly well suited for performing the method such.
B. those chromium compounds of aliphatic oxycarboxylic acids or, preferably, aromatic o-oxycarboxylic acids, which contain the chromium in a complex bond. 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 agents promoting the complex formation.
Example: 21.6 parts of 2-amino-1-oxybenzene-4-sulphonic acid dimethylamide are dissolved in 50 parts of water and 14 parts of 30% hydrochloric acid and, at 0 to 5, with an aqueous solution of 6.9 parts of sodium nitrite diazotized. The diazo suspension neutralized with sodium carbonate is at 10 to 12 in a solution of 18.3 parts of 1-phenyl-3-methyl-5-pyrazolone, 50 parts of water and 14,
Poured in 0 parts of 30% sodium hydroxide solution. The coupling is very quick. The dye is completely separated out by adding sodium chloride.
The dye paste obtained by filtering off is stirred in 250 parts of water and treated with 120 parts of a solution of sodium / potassium chromsalieylic acid with a chromium content of 2.6% and 6.7 parts of 30% sodium hydroxy d solution added. The whole is refluxed for 3 hours. After this time, the chroming is finished. The chromium-containing dye is isolated by evaporating the reaction mixture in vacuo.
