Description

  

  Verfahren zur Herstellung eines neuen     Azofar        bstoües.       Es wurde gefunden, dass man einen neuen       Azofarbstoff    erhält, wenn man das     1-Oxy-          naphthalin-5-sulf        amid    mit     diazotierter        1-          Oxynaphthalin    - 8 -     sulf        amid-    2     -amino    -4 -     sulf        o-          säure    kuppelt.

   Der neue Farbstoff bildet ein  braunes Pulver und färbt Wolle im essig  sauren Bade in rotvioletten Farbtönen, wel  che beim     Nachchromieren    teilweise unter Zer  setzung graublau, beim Nachkupfern rotvio  lett und echt werden.  



  <I>Beispiel</I>  22,8 Teile     1-Oxynaphthalin-5-sulfamid     werden in eine Lösung von 56 Teilen     Ätz-          kali    in 48 Teilen Wasser bei     40-45      einge  tragen. Die so erhaltene Mischung wird hier  auf mit der     Diazoverbindung    aus 31,8 Teilen       1-Oxynaphthalin-8-sulf        amid-2-amino-4-sul    f o  säure in Form einer 49%igen Paste versetzt.    Nach beendeter Kupplung verdünnt man mit  200 Teilen kaltem Wasser, lässt 280 Teile  15%ige Salzsäure unter Rühren einlaufen  und salzt den neuen Farbstoff aus.



  Process for the production of a new azo color. It has been found that a new azo dye is obtained when 1-oxynaphthalene-5-sulfamide is coupled with diazotized 1-oxynaphthalene-8-sulfamide-2-amino -4-sulfo acid.

   The new dye forms a brown powder and dyes wool in an acidic bath in red-violet shades, which when chrome-plating sometimes become gray-blue with decomposition, and red-violet and real when copper is plated.



  <I> Example </I> 22.8 parts of 1-oxynaphthalene-5-sulfamide are added to a solution of 56 parts of caustic potash in 48 parts of water at 40-45. The mixture obtained in this way is mixed with the diazo compound from 31.8 parts of 1-oxynaphthalene-8-sulfamide-2-amino-4-sulfamide in the form of a 49% paste. When the coupling is complete, it is diluted with 200 parts of cold water, 280 parts of 15% strength hydrochloric acid are run in with stirring and the new dye is salted out.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Azofarbstoffes, dadurch gekennzeichnet, dass man das 1-Oxynaphthalin-5-sulfamid mit dia- zotierter 1-Oxynaphtalin-8-sulfamid-2-amino- 4-sulfosäure kuppelt. Der neue Farbstoff bildet ein braunes Pulver und- färbt Wolle im essigsaurem Bade in rotvioletten Farb tönen, welche beim Nachchromieren teilweise unter Zersetzung graublau, beim Nach kupfern rotviolett und echt werden. PATENT CLAIM: A process for the production of a new azo dye, characterized in that 1-oxynaphthalene-5-sulfamide is coupled with diazotized 1-oxynaphthalene-8-sulfamide-2-amino-4-sulfonic acid. The new dye forms a brown powder and dyes wool in an acetic acid bath in red-violet hues, which when chromium-plating sometimes become gray-blue with decomposition, and red-violet and real when copper is applied.
