Description
Zusatzpatent zum 13auptpatent Nr. 101614. Verfahren zur Herstellung eines neuen Azofarüstoffes. Es wurde gefunden, da,ss man einen neuen Azofarbstoff erhält, wenn man die 1-Oxy- naphthalin-8-sulfamid-4-sulfosäure mit diazo- tiertem 4-Nitro-6-chlor-l-oxy-2-aminobenzol kuppelt.
Der neue Farbstoff bildet ein dunk les Pulver und färbt Wolle im essigsauren Bade in schwarzvioletten Farbtönen, welche beim Nachchromieren hellbraunviolett, beim Nachkupfern blaurot und echt werden.
<I>Beispiel:</I> 1.8,85 Teile 4-1\Titro-6-ehlor-l-oxy-2-amino- benzol werden in üblicher Weise diazotiert und zu einer Lösung von 80,3 Teilen 1-Oxy- naphthalin-8-sulfamid-4-sulfosäure, 10 Teilen Natronhydrat und 25 Teilen Soda in 200 Tei len Wasser gegeben. Man rührt bei 5 bis 10 , bis die Dia\overbindung verschwunden ist und scheidet den gebildeten Farbstoff durch Aussalzen und Filtrieren ab.
Additional patent to the 13th main patent no. 101614. Process for the production of a new azo-aromatic substance. It has been found that a new azo dye is obtained if 1-oxynaphthalene-8-sulfamide-4-sulfonic acid is coupled with diazotized 4-nitro-6-chloro-1-oxy-2-aminobenzene.
The new dye forms a dark powder and dyes wool in the acetic acid bath in black-violet shades, which become light brown-violet when chrome-plating and blue-red and real when copper-plating.
<I> Example: </I> 1.8.85 parts of 4-1 \ Titro-6-chloro-1-oxy-2-aminobenzene are diazotized in the usual way and a solution of 80.3 parts of 1-oxy- naphthalene-8-sulfamide-4-sulfonic acid, 10 parts of sodium hydrate and 25 parts of soda in 200 Tei len water. The mixture is stirred at 5 to 10 until the diamond bond has disappeared and the dye formed is separated off by salting out and filtering.
