Description
Zusatzpatent zum Hauptpatent Nr. <B>200672.</B> Verfahren zur Herstellung eines neuen Azofarbstoffes. Es wurde gefunden, dass man einen neuen Azofarbstoff, erhält, wenn man<B>1</B> Mol <B>2-(3-</B> [4"-Aminol-betizoylamino-5'-amino)-berizoyl- amino-5-oxyiiaphthalin-7-sulfonsäuremitIMol des diazotierten Monoazofarbstoffes,
erhalten durch Kuppeln von<B>1</B> Mol diazotierter 2-Amino- iiaphthalin-4. 8-disulfonsäure mit<B>1</B> Mol 1- Aminonaphthalin und Weiterdiazotieren, ver einigt.
Der so erhaltene Farbstoff bildet ein graues Pulver, das sich in Wasser mit violett- blauer Farbe löst und Baumwolle in violetten Tönen färbt, die durch Weiterdiazotieren auf der Faser und Entwickeln mit 1-Phenyl-3- methyl-5-pyrazolon stumpfgrün werden. <I>Beispiel:</I> 303 Teilo 2-Aminonaphthalin-4.8-disulfon- säure werden in ühlicher Weise diazotiert und mit 143 Teilen 1-Aminonaphthalin ge kuppelt.
Daraus wird nach gewohnter Art die Diazoverbindung hergestellt und gereinigt. Die Diazosuspension wird in eine kalte Lö sung aus etwa 400 Teilen 2-(3'-[4"-Amino] benzoylamino-5'-amino)-benzoylamino-5-oxy- naphthaliii-7-sulfonsäure, <B>300</B> Teilen Natrium- earbonat und<B>5000</B> Teilen Wasser eingerührt. Nach beendeter Kupplung wird der Farbstoff, gegebenenfalls nach Aussalzen, abfiltriert und getrocknet.
Additional patent to main patent no. <B> 200672. </B> Process for the production of a new azo dye. It has been found that a new azo dye is obtained if <B> 1 </B> mol <B> 2- (3- </B> [4 "-aminol-betizoylamino-5'-amino) -berizoyl] - amino-5-oxyiiaphthalene-7-sulfonic acid with 1 mol of the diazotized monoazo dye,
obtained by coupling <B> 1 </B> mol of diazotized 2-amino-iiaphthalene-4. 8-disulfonic acid with <B> 1 </B> mol 1-aminonaphthalene and further diazotization, united.
The dye thus obtained forms a gray powder which dissolves in water with a violet-blue color and dyes cotton in violet tones which become dull green when the fibers are further diazotized and developed with 1-phenyl-3-methyl-5-pyrazolone. <I> Example: </I> 303 parts of 2-aminonaphthalene-4.8-disulfonic acid are diazotized in the usual way and coupled with 143 parts of 1-aminonaphthalene.
From this the diazo compound is produced and cleaned in the usual way. The diazo suspension is dissolved in a cold solution of about 400 parts of 2- (3 '- [4 "-amino] benzoylamino-5'-amino) -benzoylamino-5-oxynaphthaliii-7-sulfonic acid, <B> 300 </ B> parts of sodium carbonate and 5000 parts of water are stirred in. After coupling has ended, the dyestuff, optionally after salting out, is filtered off and dried.
