Description
Verfahren zur Herstellung eines nickelhaltigen Polyazofarbstoffes der Stilbenreihe Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung eines nickel- haltigen Polyazofarbstoffes der 'Stilbenreihe, welches darin besteht,
dass man 1 1VIol der Aminodisazoverbindung der Zusammensetzung
EMI0001.0011
diazotiert und den Diazokörper mit 1 lhol der Nickelkomplexverbindung von 2,2',4'-Tri- oxy-1,1'-azobenzol-5-sulfonsäure vereinigt.
Der neue, nickelhaltige Polyazofarbstoff der Stilbenreihe ist ein braunschwarzes Pul ver, welches sich 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> 6-1,3 Teile der Aminodisazoverbindung der Zusammensetzung
EMI0001.0026
werden in Form des Natriumsalzes in<B>1000</B> Teilen Wasser gelöst imd durch Zugabe einer Lösung von 7 Teilen Natriumnitrit in 20 Tei len Wasser und 30 Teilen 30prozentiger Salz säure bei 10 diazotiert. Die Lösung der Di- azoverbindung lässt man in eine eisgekühlte <B>Losung</B> von<B>36,
7</B> Teilen der Nickelkomplex- v erbindung aus 2,2',4'-Trioxy-1,1'-azobenzol-:j- sulfonsäure und 40 Teilen Natriumcarbonat in 400 Teilen Wasser fliessen. Nach beendig ter Kuppltmg wird der erhaltene nickelhaltige Polyazofarbstoff durch Zusatz von Natrium chlorid abgeschieden, von der Lösung abfil- triert und getrocknet.
Er ist ein braunschwar zes Pulver, löst sich in Wasser mit. violett brauner Farbe und färbt Chromvelourleder in violettstichig braunen, schleifechten Tönen.
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
that one 1 1VIol of the aminodisazo compound of the composition
EMI0001.0011
diazotized and combined the diazo body with 1 lhol of the nickel complex compound of 2,2 ', 4'-trioxy-1,1'-azobenzene-5-sulfonic acid.
The new, nickel-containing polyazo dye from the stilbene range is a brown-black powder that dissolves in water with a violet-brown color and dyes chrome suede in violet, brown, abrasive tones.
In the following example, the parts mean parts by weight, and. the percentages are given in percentages by weight. <I> Example </I> 6-1.3 parts of the aminodisazo compound of the composition
EMI0001.0026
are dissolved in the form of the sodium salt in 1000 parts of water and diazotized at 10 by adding a solution of 7 parts of sodium nitrite in 20 parts of water and 30 parts of 30 percent hydrochloric acid. The solution of the diazo compound is left in an ice-cold <B> solution </B> of <B> 36,
7 parts of the nickel complex compound of 2,2 ', 4'-trioxy-1,1'-azobenzene-: j-sulfonic acid and 40 parts of sodium carbonate flow in 400 parts of water. After the coupling has ended, the nickel-containing polyazo dye obtained is deposited by adding sodium chloride, filtered off from the solution and dried.
It is a brown-black powder that dissolves in water. violet-brown color and dyes chrome suede in violet-tinged brown, abrasive tones.
