Description
Verfahren zur Herstellung eines neuen Azofarbstoffes. Es wurde gefunden, dass man einen neuen Azofarbstoff erhält, wenn man die 1-Oxy- naphtha,Iin-8-sulfamid-3-stilfosäure mit diano tiertem 4-Chlor-2-amino-l-oxybenzolkuppelt. Der neue Farbstoff bildet ein dunkles Pul ver und färbt -Volle im essigsauren Bade in blauroten Farbtönen, welche beim NacUchro- mieren violett, beim Nachkupfern rotviolett und echt werden.
Beispiel: 14,35 Teile 4-Chlor-2-amino-l-oxybenzol werden in üblicher Weise dianotiert und zu einer Lösung von 30,3 Teilen 1-Oxynaphtha- lin-8-sulfamid-3-sulfosäure, 10 Teilen Natron hydrat und 25 Teilen Soda in 200 Teilen Wasser gegeben. Man rührt bei 5 bis<B>10',</B> bis die Diazoverbindung verschwunden ist und scheidet den gebildeten Farbstoff durch Aussalzen und Filtrieren ab.
Process for the production of a new azo dye. It has been found that a new azo dye is obtained when 1-oxynaphtha, Iin-8-sulfamide-3-stilfoic acid is coupled with diano-tated 4-chloro-2-amino-1-oxybenzene. The new dye forms a dark powder and colors the whole thing in the acetic acid bath in blue-red shades, which become violet when chroming and red-violet when re-coppering.
Example: 14.35 parts of 4-chloro-2-amino-1-oxybenzene are dianotized in the usual way and hydrate to a solution of 30.3 parts of 1-oxynaphthalin-8-sulfamide-3-sulfonic acid, 10 parts of sodium Put 25 parts of soda in 200 parts of water. The mixture is stirred at 5 to 10 'until the diazo compound has disappeared and the dye formed is separated off by salting out and filtering.
