Description
Verfahren zur Herstellung eines metallhaltigen Azofarbstoffes. Es wurde gefunden, dass man zu einem wertvollen, neuen, metallhaltigen Azofarb- stoff gelangt, wenn man auf den Monoazo- farbstoff der Formel
EMI0001.0011
chromabgebende Mittel derart einwirken lässt, dass ein ehromlia.ltiger Azofarbstoff entsteht,
der zwei Monoazofarbstoffmoleküle an ein Chromatom komplex gebunden enthält.
Der neue chromhaltige Farbstoff bildet ein wasserlösliches graues Pulver, das Wolle aus neutralem oder essigsaurem Bade in grauen Tönen färbt.
Der als Ausgangsstoff dienende, der oben stehenden Formel entsprechende Monoazofarb- stoff kann durch Kupplung des 1-Carbäthoxy- amino-7-oxynaphthalins mit nach an sich be kannten Methoden, z. B. mittels Salzsäure und Natriumnitrit dianotiertem 2-Amino=l-ox37ben- zol-4-sulfonsäureanilid-2'-carbonsäure herge stellt 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 erfahrungsgemäss komplexe Chromverbindun gen dieser Zusammensetzung liefern. Es emp fiehlt sich im allgemeinen, auf ein Molekül eines Farbstoffes weniger als ein, mindestens aber ein halbes Atom Chrom zu verwenden und(oder die Chromierung in schwach saurem bis alkalischem lfledium auszuführen. Demzu folge sind auch diejenigen Chromverbindun gen, die in alkalischem Medium beständig sind, für die Durchführung des Verfahrens beson ders gut geeignet, wie z.
B. solche Chromver bindungen aliphatischer Oxycarbonsäuren oder vorzugsweise aromatischer o-Oxycarbonsätiren, welche das Chrom in komplexer Bindung ent halten. Die Chromierung geschieht mit Vorteil in der Wärme, offen oder unter Druck, z. B. bei Siedetemperatur des Reaktionsgemisches, gegebenenfalls in Anwesenheit geeigneter Zu sätze, z. B. in Anwesenheit von Salzen organi scher Säuren, von Basen, organischen Lösungs mitteln oder weiteren die Komplexbildung för dernden Mitteln.
<I>Beispiel:</I> 30,8 Gewichtsteile l.-Oxy-2-aminobenzol-4- sulfonsäure-N-phenylamid-2'-carbonsäure wer- den in 150 Teilen Wasser und 22 Teilen 10n- Natronlauge gelöst. Die erhaltene klare Lö sung wird mit 25 Teilen 4n-Natriumnitritlösung versetzt und bei 0 bis 2 in eine Mischung von 110 Teilen Wasser und 40 Teilen 10n-Salz- säLire eingetropft.
Die entstandene hellgelbe Diazosuspension wird mit Natriumcarbonat neutralisiert und zu einer eisgekühlten Lösung von 23,5 Teilen 7-Oxynaphthyl-(1)-carbamin- säureäthylester in 100 Teilen Wasser, 52 Vo- lumteilen 2n-N atriumhydroxydlösung und 50 Volumteilen 2n-Natriumcarbonatlösnng zulau fen gelassen. Nach beendeter Kupplung wird der abgeschiedene Farbstoff filtriert und mit verdünnter Natriumchloridlösung gewaschen.
Der nach obigen Angaben erhaltene Filter kuchen des Farbstoffes wird in 1500 Teilen Wasser aufgeschlämmt und mit 200 Teilen einer Lösung von chromsalicylsaurem Kalium- Natrium mit einem Chromgehalt von 1,85% versetzt. Die Lösung von chrornsalieylsaurem Kalium-Natrium erhält man z.
B. durch Auf kochen von 100 Teilen einer Chromsulfatlö- sung ('Cr-S040H) mit einem Chromgehalt von 3,7% mit 19,6 Teilen Salicylsäure,
Lösen des entstandenen Niederschlages durch Zugabe von 15 Volumteilen lOn-Natriumhydroxyd- lösung -Lind 15 Volumteilen lOn-Kalium- hydroxy dlösung und Einstellen mit Wasser auf 200 Teile.
Das Chromiergemisch wird während etwa 5 Stunden bei Siedetemperatur gehalten und die so erhaltene Chromverbin dung des Farbstoffes durch Natriiunchlorid- zugabe abgeschieden -Lind abfiltriel-t.
Process for the preparation of a metal-containing azo dye. It has been found that a valuable, new, metal-containing azo dye is obtained when one uses the monoazo dye of the formula
EMI0001.0011
lets chromium-releasing agents act in such a way that an Ehromlia.
which contains two monoazo dye molecules bound to a chromium atom in a complex.
The new chromium-containing dye forms a water-soluble gray powder that dyes wool from neutral or acetic acid baths in gray tones.
The starting material used, the above formula corresponding monoazo dyestuff can be prepared by coupling the 1-carbethoxy amino-7-oxynaphthalene with methods known per se, for. B. by means of hydrochloric acid and sodium nitrite dianotized 2-amino = l-ox37ben- zene-4-sulfonic acid anilide-2'-carboxylic acid can be Herge. 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 expediently carried out 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, but at least half an atom of chromium on a molecule of a dye and (or carry out the chromating in a weakly acidic to alkaline oil medium. As a result, those chromium compounds which are stable in an alkaline medium are also are particularly well suited for carrying out the process, such as.
B. such Chromver bonds of aliphatic oxycarboxylic acids or preferably aromatic o-Oxycarbonsätiren, which keep the chromium in complex bonds ent. The chromizing is done with advantage in the heat, open or under pressure, z. B. at the boiling point of the reaction mixture, optionally in the presence of suitable additives to, for. B. in the presence of salts of organic shear acids, bases, organic solvents or other agents promoting the complex formation.
<I> Example: </I> 30.8 parts by weight of 1.-oxy-2-aminobenzene-4-sulfonic acid-N-phenylamide-2'-carboxylic acid are dissolved in 150 parts of water and 22 parts of 10N sodium hydroxide solution. The clear solution obtained is mixed with 25 parts of 4N sodium nitrite solution and added dropwise at 0 to 2 to a mixture of 110 parts of water and 40 parts of 10N salt säLire.
The resulting pale yellow diazo suspension is neutralized with sodium carbonate and added to an ice-cold solution of 23.5 parts of 7-oxynaphthyl- (1) -carbamic acid ethyl ester in 100 parts of water, 52 parts by volume of 2N sodium hydroxide solution and 50 parts by volume of 2N sodium carbonate solution calmly. After the coupling has ended, the deposited dye is filtered and washed with dilute sodium chloride solution.
The filter cake of the dye obtained according to the above information is suspended in 1500 parts of water and treated with 200 parts of a solution of chromium salicylic acid potassium-sodium with a chromium content of 1.85%. The solution of chrornsalieylsaurem potassium-sodium is obtained z.
B. by boiling 100 parts of a chromium sulfate solution ('Cr-S040H) with a chromium content of 3.7% with 19.6 parts of salicylic acid,
Dissolve the precipitate formed by adding 15 parts by volume of 10n sodium hydroxide solution and 15 parts by volume of 10n potassium hydroxide solution and adjusting to 200 parts with water.
The chromating mixture is kept at boiling temperature for about 5 hours and the chromium compound of the dye obtained in this way is deposited by adding sodium chloride - Lind is filtered off.
