Description

  

  Verfahren zur Herstellung eines     Azofarbstoffes.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines     Azofarbstoffes,     dadurch gekennzeichnet, dass man die     Diazo-          verbindung    von     6-Chlor-2-amino-l-oxybenzol     mit     1.5-Di-(acetylamino)-3-oxynaphthalin-7-          sulfonsäure    vereinigt.  



  Der Farbstoff ist getrocknet ein dunkles  Pulver, das sich in verdünnten Säuren mit  roter, in     Natriumcarbonatlösung    mit blauer  und in konzentrierter Schwefelsäure mit blau  stichig-roter Farbe löst, und färbt Wolle in  roten Tönen, die beim     Chromieren    in rot  stichig-graue Töne von sehr guter Licht-,       Walk-,        Carbonisier-    und     Pottingechtheit    über  gehen.  



  <I>Beispiel:</I>  14,3 Gewichtsteile     6-Chlor-2-amino-l-oxy-          benzol    werden     diazotiert.    Die     Diazolösung     lässt man in eine überschüssiges     Natrium-          carbonat    enthaltende Lösung von 33,8     Teilen     1. 5-Di-(acetylamino)-3-oxynaphthalin-7-sulfon-         säure    einlaufen. Nach beendeter     Kupplung     wird der Farbstoff abgeschieden und ge  trocknet.



  Process for the preparation of an azo dye. The present patent relates to a process for the production of an azo dye, characterized in that the diazo compound of 6-chloro-2-amino-1-oxybenzene is combined with 1,5-di- (acetylamino) -3-oxynaphthalene-7-sulfonic acid .



  The dyestuff is a dried dark powder that dissolves in dilute acids with red, in sodium carbonate solution with blue and in concentrated sulfuric acid with bluish-red color, and dyes wool in red tones, which when chrome-plated in red, cast-gray tones of very good fastness to light, fulling, carbonising and potting.



  <I> Example: </I> 14.3 parts by weight of 6-chloro-2-amino-1-oxybenzene are diazotized. The diazo solution is allowed to run into a solution of 33.8 parts of 1,5-di- (acetylamino) -3-oxynaphthalene-7-sulfonic acid containing excess sodium carbonate. After the coupling has ended, the dye is deposited and dried.
