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.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Azofarbstoffes, dadurch gekennzeichnet, da.ss _man die 1-Oxynaphthalin-8-sulfamid-3-stilfo-. säure mit dianotiertem 4-Chlor-2-amino-l- oxybenzol kuppelt. Der neue Farbstoff bil det ein dunkles Pulver und färbt Wolle im essigsauren Bade in blauroten Farbtönen, wel che beim Nachchromieren violett, beim Nach kupfern rotviolett und echt werden. PATENT CLAIM: Process for the production of a new azo dye, characterized in that the 1-oxynaphthalene-8-sulfamide-3-stilfo-. acid coupled with dianotated 4-chloro-2-amino-l-oxybenzene. The new dye forms a dark powder and dyes wool in an acetic acid bath in blue-red shades, which become violet when chromium plating and red-violet and real when copper is applied.
