Description

  

  Verfahren zur     Herstellung    eines neuen     Azofarbstofes.       Es wurde gefunden, dass man einen neuen       Azofarbstoff    erhält, wenn man das     1-Oxy-          naphthalin-3,8-disulfamid    mit     diazotiertem        4-          Chlor-2-amino-l-oxybenzol    kuppelt. Der neue  Farbstoff bildet ein     schwärzlichbraunes    Pul  ver und färbt Wolle im essigsauren Bade in  Braunbordeaux Farbtönen, welche beim     Nach-          chromieren    rotblau, beim Nachkupfern vio  lett und echt werden.  



       Beispiel:     14,3 Teile     4-Chlor-2-amino-l-oxybenzol     werden in üblicher Weise     diazotiert    und bei  <B>5-10'</B> in eine Lösung von 30,2 Teilen     1-          Oxynaphthalin    - 3,8 -     disulfamid,    27 Teilen  30     %iger    Natronlauge, 10 Teilen Soda in 90  Teilen Wasser eingetragen. Man rührt bei    <B>10'</B> bis zur vollendeten Kupplung, verdünnt  mit 150 Teilen Wasser und giesst das Reak  tionsgemisch in 140 Teile einer 15     %igen    Salz  säure und salzt aus.



  Process for the preparation of a new azo dye. It has been found that a new azo dye is obtained when 1-oxynaphthalene-3,8-disulfamide is coupled with diazotized 4-chloro-2-amino-1-oxybenzene. The new dye forms a blackish-brown powder and dyes wool in an acetic acid bath in brown-burgundy shades, which become red-blue when chrome-plated, and purple and real when copper-plated.



       Example: 14.3 parts of 4-chloro-2-amino-1-oxybenzene are diazotized in the usual way and at <B> 5-10 </B> in a solution of 30.2 parts of 1-oxynaphthalene - 3.8 - Disulfamide, 27 parts of 30% sodium hydroxide solution, 10 parts of soda added to 90 parts of water. The mixture is stirred at <B> 10 '</B> until coupling is complete, diluted with 150 parts of water and the reaction mixture is poured into 140 parts of a 15% hydrochloric acid and salted out.
