Description
Verfahren zur Herstellung eines neuen Azofarbstoffes. Es wurde gefunden, dass man einen neuen Azofarbstoff erhält, wenn man 1 Mol 1-(3'- [3"- (4"'- Amino) -benzoylamino - 5" - aminol - benzoylamino)-phenyl- 5 -pyrazolon-3-carbon- säure mit 1 Mol diazotierter Sulfanilsäure vereinigt.
Der so erhaltene Farbstoff bildet ein hellviolettbraunes Pulver, das sich in Wasser mit gelber Farbe löst und Baum wolle in gelben Tönen färbt, die durch ZV ei- terdiazotieren auf der Faser und Entwickeln mit ss-Naphthol intensiv orangerot werden.
<I>Beispiel:</I> 173 Teile Sulfanilsäure werden in üb licher Weise diazotiert. Die Diazolösung wird in eine kalte; mit 10 J iger Essigsäure schwach angesäuerte Lösung aus 496 Teilen 1- (3'- [3" - (4"' - Amino) - benzoylamino - 5" amino] -benzoylamino) -phenyl-5-pyrazolon-3- carbonsäure, 140 Teilen Natronlauge ä 30%, 200 Teilen kristallisiertem Natriumacetat und 20 000 Teilen Wasser eingerührt.
Nach beendeter Kupplung wird der Farbstoff aus gesalzen, abfiltriert und getrocknet.
Process for the production of a new azo dye. It has been found that a new azo dye is obtained if 1 mole of 1- (3'- [3 "- (4" '- amino) -benzoylamino - 5 "- aminol - benzoylamino) -phenyl-5-pyrazolone-3 carbonic acid combined with 1 mol of diazotized sulfanilic acid.
The dye obtained in this way forms a light purple-brown powder which dissolves in water with a yellow color and dyes cotton in yellow tones which become intensely orange-red when the fibers are diazotized with pus and developed with s-naphthol.
<I> Example: </I> 173 parts of sulfanilic acid are diazotized in the usual way. The diazo solution is in a cold; solution of 496 parts of 1- (3'- [3 "- (4" '- amino) - benzoylamino - 5 "amino] -benzoylamino) -phenyl-5-pyrazolone-3-carboxylic acid, weakly acidified with 10 J acetic acid, 140 Parts of 30% sodium hydroxide solution, 200 parts of crystallized sodium acetate and 20,000 parts of water are stirred in.
After coupling has ended, the dyestuff is salted out, filtered off and dried.
