Description

  

  Verfahren zur Herstellung eines neuen     Honoazofarbstoffes.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines neuen Mono  azofarbstoffes, dadurch gekennzeichnet, dass  man die     Diazoverbindung    von     4-Aminodi-          phenyläther-3-sulfosäure    mit der     2-Dlethoxy-          acetylamino-8-napthol-6-sulfosäure    kuppelt.  



  Der erhaltene Farbstoff stellt ein braun  rotes wasserlösliches Pulver dar und färbt  die animalische Faser in     egalen,    lebhaften,       gelbstichigroten,    lichtechten Tönen.  



  <I>Beispiel</I>  26,5 kg     4-Aminodiphenyläther-3-sulfo-          säure    werden in der üblichen Weise diano  tiert und die erhaltene     Diazolösung    wird mit  einer Lösung von     322    kg der     2-DIethoxyacetyl-          amino-8-naphtol-6-sulfosäure    unter Zusatz von         Natriumacetat    gekuppelt. Der gebildete Farb  stoff wird in üblicher Weise isoliert und ge  trocknet.



  Process for the production of a new honoazo dye. The present patent relates to a process for the production of a new mono azo dye, characterized in that the diazo compound of 4-aminodiphenyl ether-3-sulfonic acid is coupled with 2-diethoxyacetylamino-8-napthol-6-sulfonic acid.



  The dye obtained is a brown-red water-soluble powder and dyes the animal fiber in level, lively, yellowish-red, lightfast shades.



  <I> Example </I> 26.5 kg of 4-aminodiphenyl ether-3-sulfonic acid are dianoed in the usual manner and the diazo solution obtained is mixed with a solution of 322 kg of 2-diethoxyacetylamino-8-naphthol 6-sulfonic acid coupled with the addition of sodium acetate. The color formed is isolated in the usual way and dried ge.
