Description
Verfahren zur Herstellung eines nickelhaltigen Polyazofarbstoffes der Stilbenreihe Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung eines niekel- lialtigen Polyazofarbstoffes der Stil'benreihe, welches darin besteht;
dass man 1 Mol 1,3- Dioxybenzol mit dem Diazokörper aus 1 Mol der Aminodisazoverbindung der Zusammen setzung
EMI0001.0016
vereinigt, auf das Kupplungsprodukt 1 Mol diazotierte 2-Amina-l-oxybenzol-4-sidfonsäure einwirken lässt und den erhaltenen Polyazo- farbstoff mit einem nickelabgebenden Mittel behandelt.
Der neue, nickelhaltige Polyazofarbstoff der Stilbenreihe ist ein braunschwarzes Pul- ver, welches sieh in Wasser mit violettbrauner Farbe löst und Chromvelourleder in violett stichig braunen, schleifechten Tönen färbt.
Im nachfolgenden Beispiel bedeuten die Teile Gewichtsteile, und die Prozente sind in Gewichtsprozenten angegeben. <I>Beispiel</I> 64,3 Teile der Aminodisazoverbindung der Zusammensetzling
EMI0001.0036
werden in Form des Natriumsalzes in 1000 Teilen Wasser gelöst.
und durch Zugabe einer Lösung von 7 Teilen Natriumnitrit in 20 Tei len Wasser und 30 Teilen 30 o/oiger Salzsäure bei 10-1ä diazotiert. Die Diazosuspension lässt man zu einer eisgekühlten Lösung aus <B>11</B> Teilen 1;3-Dioxvbenzol, 40 Teilen Nat.rium- earbonat und 200 Teilen Wasser fliessen.
Hier- auf fügt man der Kupphingslbsting vorerst weitere 40 Teile Natriumearbonat und her nach die Diazoverbindung aus 18,9 Teilen 2-Amino@l-oxybenzol-4-sulfonsäure zii. Nach beendigter Kupplung wird der erhaltene Polyazofarbstoff dilrch Zusatz von Natrium- ehlorid aus der Lösung ausgefällt und ab filtriert.
Zur 1Fetallisierung des Polpazofarbstoffes löst man den feuchten Filterkuchen in 1000 Teilen Wasser von 65 , fügt der Lösung 20 Teile Natriumacetat und eine konzentrierte wässerige Lösung von 28 Teilen kristallisier tem Nickelsulfat hinzu und rührt die Metalli- sierungslösung während 3 Stunden bei 65 bis 70 .
Der nickelhaltige Polyazofarbstoff wird mittels Na.triumchlorid aus der Lösung aus gefällt, von derselben abfilt.riert und getroeli:- net. Er ist ein braunschwarzes Pulver, das sieh in Wasser mit violet.tbrauner Farbe löst und Chromvelourleder in violettstiehig braunen, sehlleifeehten Tönen färbt.
Process for the production of a nickel-containing polyazo dye of the stilbene series The subject of the present patent is a process for the production of a nickel-containing polyazo dye of the stilbene series, which consists in this;
that 1 mole of 1,3-dioxybenzene with the diazo body from 1 mole of the aminodisazo compound of the composition
EMI0001.0016
combined, allowed to act on the coupling product 1 mol of diazotized 2-amina-1-oxybenzene-4-sidfonic acid and treated the resulting polyazo dye with a nickel-releasing agent.
The new, nickel-containing polyazo dye of the stilbene series is a brown-black powder, which dissolves in water with a violet-brown color and dyes chrome suede in violet, brown, abrasion-resistant tones.
In the following example, parts are parts by weight and percentages are percentages by weight. <I> Example </I> 64.3 parts of the aminodisazo compound of the composition
EMI0001.0036
are dissolved in 1000 parts of water in the form of the sodium salt.
and diazotized at 10-1ä by adding a solution of 7 parts of sodium nitrite in 20 parts of water and 30 parts of 30% hydrochloric acid. The diazo suspension is allowed to flow into an ice-cooled solution of 11 parts of 1,3-dioxvbenzene, 40 parts of sodium carbonate and 200 parts of water.
Thereupon, a further 40 parts of sodium carbonate are first added to the Kupphingslbsting and then the diazo compound from 18.9 parts of 2-amino @ l-oxybenzene-4-sulfonic acid is added. When the coupling is complete, the polyazo dye obtained is precipitated from the solution with the addition of sodium chloride and filtered off.
To metallize the polpazo dye, the moist filter cake is dissolved in 1000 parts of water of 65, 20 parts of sodium acetate and a concentrated aqueous solution of 28 parts of crystallized nickel sulfate are added to the solution and the metallization solution is stirred for 3 hours at 65 to 70.
The nickel-containing polyazo dye is precipitated from the solution using sodium chloride, filtered off from the same and dried. It is a brown-black powder that dissolves in water with a violet-brown color and dyes chrome suede in violet-brown, smooth tones.
