Description
Verfahren zur Herstellung eines neuen Azofarbstoffes. Es wurde gefunden, dass ein neuer Azo- farbstoff erhalten wird, wenn man 1 Mol. diazotierte 2-Amino-l-oxybenzol-4-sulfosäure auf 2 Mol. ss-Naphthylamin einwirken lässt und die so erhaltene Doppelverbindung, be stehend aus dem Azofarbstoff und ss-Naph- thylamin, mit verseifend wirkenden Mitteln behandelt.
Der so erhaltene Farbstoff bildet ein braunrotes Pulver, löst sich mit oranger Farbe in Wasser, färbt Wolle aus saurem

Bade <SEP> orange <SEP> und <SEP> ist <SEP> ein <SEP> wertvolles <SEP> Aus- stoffes und ss-Naphthylamin, wird mit kal ter Natronlauge behandelt. Es bildet sich unter Abspaltung von ss-Naphthylamin eine orange Lösung, aus welcher nach der Fil tration der reine o-Aminoazofarbstoff durch Aussalzen abgeschieden wird.
Process for the production of a new azo dye. It has been found that a new azo dye is obtained if 1 mol of diazotized 2-amino-1-oxybenzene-4-sulfonic acid is allowed to act on 2 mol of β-naphthylamine and the double compound thus obtained, consisting of the azo dye and ss-naphthylamine, treated with saponifying agents.
The dye thus obtained forms a brown-red powder, dissolves in water with an orange color, dyes wool from acidic

Bath <SEP> orange <SEP> and <SEP> is <SEP> a <SEP> valuable <SEP> substance and ss-naphthylamine, is treated with cold caustic soda. An orange solution is formed with elimination of β-naphthylamine, from which the pure o-aminoazo dye is deposited by salting out after the filtration.
