Description
Verfahren zur Herstellung eines chromhaltigen Polyazofarbstoffes der Stilbenreihe Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung eines chrom- haltigen Polyazofarbstoffes der Stilbenreihe, welches darin besteht,
dass man 1 Mol der Aminod'isazoverbindung der Formel
EMI0001.0014
dia.zotiert und den Diazokörper mit 1 Mol der Chromkomplexv erbindung von 2,2',4'-Trioxy- 1,1.'-azobenzol-5-sulfonsäure vereinigt.
Der neue, chromhaltige Polyazofarbstoff der Stilbenreihe ist ein braunes Pulver, wel ehes ;sieh in Wasser mit orangebrauner Farbe löst und Chromvelourleder in gelbstichig braunen, schleifechten Tönen färbt.
Im nachfolgenden Beispiel bedeuten die Teile Gewichtsteile, und die Prozente send in Gewichtsprozenten angegeben. <I>Beispiel</I> 64,3 Teile der Aminod'isazoverbind'ung der Zusammensetzung
EMI0001.0035
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 diazotiert. Die Lösung der Diazover- bindung lässt man in eine eisgekühlte Lösung von 36 Teilen der Chr omkomplexver bindung aus 2,2',4'-Trioxy-1,
1'-azobenzol-5-siilfonsäure und 40 Teilen Natriumcarbonat in 400 Teilen Wasser fliessen. Nach beendigter Kupplung wird der erhaltene chromhaltige Polyazofarb- stoff mittels Natriumchlorid abgeschieden, von der Lösung abfiltriert und getrocknet. Er ist ein braunes, in Wasser mit orangebrauner Farbe lösliches Pulver,
welches Chromvelbur- leder in gelbstiehig braunen, schleifechten Tö nen färbt.
Process for the production of a chromium-containing polyazo dye of the stilbene series The subject of the present patent is a process for the production of a chromium-containing polyazo dye of the stilbene series, which consists in
that one mole of the aminod'isazo compound of the formula
EMI0001.0014
dia.zotiert and the diazo body combined with 1 mol of the chromium complex compound of 2,2 ', 4'-trioxy-1,1 .'-azobenzene-5-sulfonic acid.
The new, chromium-containing polyazo dye of the stilbene series is a brown powder, which dissolves in water with an orange-brown color and dyes chrome suede in yellowish brown, sand-resistant tones.
In the following example, the parts are parts by weight and the percentages are given in percentages by weight. <I> Example </I> 64.3 parts of the aminod'isazo compound of the composition
EMI0001.0035
are in the form of the sodium salt in.
Dissolved 1000 parts of water and by adding a solution of 7 parts of sodium nitrite. diazotized at 10 in 20 parts of water and 30 parts of 30% hydrochloric acid. The solution of the diazo compound is left in an ice-cold solution of 36 parts of the chromium complex compound of 2,2 ', 4'-trioxy-1,
1'-azobenzene-5-silfonic acid and 40 parts of sodium carbonate flow in 400 parts of water. When the coupling is complete, the chromium-containing polyazo dye obtained is precipitated using sodium chloride, filtered off from the solution and dried. It is a brown powder soluble in water with an orange-brown color,
which chrome suede dyes in yellowish brown, abrasion-resistant tones.
