Description
Verfahren zur Herstellung eines Trisazofarbstoffes. Es wurde gefunden, dass man einen Trisazo- farbstoff erhält, wenn man den Disazofarbstoff, der erhalten wird durch Vereinigen von diazo- tiertem 1-Amino-4-acetylaminobenzol mit 1- Amino-3-methylbenzol, Weiterdiazotieren des so erhaltenen Monoazofarbstoffes und Vereini gen in alkalischem Medium mit der 2-Amino- 8-oxynaphthalin-6-sulfonsäure,
diazotiert und mit 1,3-Dioxybenzol vereinigt.
Der neue Farbstoff bildet ein dunkles, bronzierendes Pulver, das sich in Wasser mit rotbrauner, in konzentrierter Schwefelsäure mit blauer Farbe löst. Der Farbstoff färbt Baumwolle in violettbraunen Tönen, die durch Nachbehandeln mit Formaldehyd oder mit 4-Nitrodiazobenzol weiter entwickelt werden können. Die mit 4-Nitrodiazobenzol erhaltenen waschechten braunen Töne sind, sowohl. neu tral als auch alkalisch, rein weiss ätzbar.
<I>Beispiel:</I> <B>15,0</B> Teile 1-Amino-4-acetylaminoberizol werden in bekannter Weise diazotiert; die Diazolösung wird durch Zusatz von 20%iger Natriumacetatlösung kongoneutral gestellt;
dann wird eine Lösung von 10,7 Teilen 1- Amino-3-methylbenzol, gelöst in 50 Teilen Wasser mit Hilfe von 13 Teilen 30 % iger Salzsäure, zugegeben. Nach 24 Stunden wird der unlösliche Monoazofarbstoff abfiltriert, dann mit 100 Teilen Wasser gut verpastet, mit weiteren 500 Teilen Wasser verdünnt.
Dann werden eine Lösung von 6,9 Teilen Natriumnitrit und 28 Teile Salzsäure von 30 % zugegeben. Das Diazotierungsgemisch wird bei<B>15-200</B> während 2-21/2 Stunden gut verrührt und dann zu einer Lösung gege ben, die durch Lösen von 23,9 Teilen 2 Amino-8-oxynaphthalin-6-sulfonsäure unter Zusatz von 30 Teilen Natriumcarbonat bereitet wurde.
Nach mehrstündigem Rühren wird der schwerlösliche Diazofarbstoff abfiltriert. Mit 800 Teilen Wasser wird er wieder angerührt, mit einer Lösung von 6,9 Teilen Natriumnitrit vermischt.
Nun werden bei 15 0 28 Teile Salz- säure von 30% eingestürzt. Nach 1-1'/2 Stunden wird die so erhaltene Suspension in eine Lösung eingerührt, die in 150 Teilen Wasser 11,0 Teile 1,3-Dioxybenzol und 30 Teile Natriumcarbönat enthält. Man rührt einige Stunden bei Raumtemperatur, neutrali siert sorgfältig den grössten Teil des Alkali- carbonates mit Salzsäure und filtriert.
Process for the preparation of a trisazo dye. It has been found that a trisazo dye is obtained when the disazo dye, which is obtained by combining diazo-tated 1-amino-4-acetylaminobenzene with 1-amino-3-methylbenzene, further diazotizing the monoazo dye thus obtained, and combining in an alkaline medium with 2-amino-8-oxynaphthalene-6-sulfonic acid,
diazotized and combined with 1,3-dioxybenzene.
The new dye forms a dark, bronzing powder that dissolves in water with a red-brown color, and in concentrated sulfuric acid with a blue color. The dye dyes cotton in violet-brown tones, which can be further developed by treating with formaldehyde or with 4-nitrodiazobenzene. The off-white tones obtained with 4-nitrodiazobenzene are, both. neutral as well as alkaline, pure white etchable.
<I> Example: </I> <B> 15.0 </B> Parts of 1-amino-4-acetylaminoberizole are diazotized in a known manner; the diazo solution is made congoneutral by adding 20% sodium acetate solution;
then a solution of 10.7 parts of 1-amino-3-methylbenzene, dissolved in 50 parts of water with the aid of 13 parts of 30% strength hydrochloric acid, is added. After 24 hours, the insoluble monoazo dye is filtered off, then pasted well with 100 parts of water and diluted with a further 500 parts of water.
Then a solution of 6.9 parts of sodium nitrite and 28 parts of 30% hydrochloric acid are added. The diazotization mixture is stirred well at 15-200 for 2-21 / 2 hours and then added to a solution which, by dissolving 23.9 parts of 2-amino-8-oxynaphthalene-6-sulfonic acid, is added Addition of 30 parts of sodium carbonate was prepared.
After several hours of stirring, the sparingly soluble disazo dye is filtered off. It is stirred up again with 800 parts of water and mixed with a solution of 6.9 parts of sodium nitrite.
Now at 15 0 28 parts of 30% hydrochloric acid collapse. After 1-1 '/ 2 hours, the suspension thus obtained is stirred into a solution which contains 11.0 parts of 1,3-dioxybenzene and 30 parts of sodium carbonate in 150 parts of water. The mixture is stirred for a few hours at room temperature, most of the alkali metal carbonate is carefully neutralized with hydrochloric acid and filtered.
