Description

  

  Verfahren zur Herstellung eines neuen     Azofar        bstoffes.       Es wurde gefunden, dass man einen neuen       Azofarbstoff    erhält, wenn man das     1-Oxy-          naphthalin-4,8-disulfamid    mit dianotierter     1-          Oxynaphthalin-2-amino-8-sulfamid    - 4 -     sulfo-          säure    kuppelt. Der neue Farbstoff bildet ein  dunkles Pulver und färbt Wolle im essig  sauren Bade in rotvioletten Farbtönen, wel  che beim     Nachchromieren    blau, beim     1Tach-          kupfern    blauviolett und echt werden.

      <I>Beispiel</I>    81,8 Teile     1-Oxynaphthalin-2-amino-8-          sulfamid-4-sulfosäure    werden wie üblich  dianotiert und bei<B>5-10'</B> in eine Lösung von  30,2 Teilen     1-Oxynaphthalin-4,8-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 Reaktionsgemisch in 140 Teile einer  15     %igen    Salzsäure und salzt aus.



  Process for the production of a new azo dye. It has been found that a new azo dye is obtained when 1-oxynaphthalene-4,8-disulfamide is coupled with dianotated 1-oxynaphthalene-2-amino-8-sulfamide-4-sulfonic acid. The new dye forms a dark powder and dyes wool in the acidic bath in red-violet hues, which become blue when chromium plating and blue-violet and real when tach copper is used.

      <I> Example </I> 81.8 parts of 1-oxynaphthalene-2-amino-8-sulfamide-4-sulfonic acid are dianotized as usual and at <B> 5-10 '</B> in a solution of 30, 2 parts of 1-oxynaphthalene-4,8-disulfamide, 27 parts of 30% strength sodium hydroxide solution, 10 parts of soda in 90 parts of water are added. The mixture is stirred at 10 'until coupling is complete, diluted with 150 parts Water and pour the reaction mixture into 140 parts of 15% hydrochloric acid and salt out.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Azofarbstoffes, dadurch gekennzeichnet, dass man das 1-Oxynaphtha_lin-4,8-disulfamidmit dianotierter 1-Oxynaphtha-Iin-2-amino-8-sul- famid-4-sulfosäure kuppelt. Der neue Farb stoff bildet ein dunkles Pulver und färbt Wolle im essigsauren Bade in rotvioletten Farbtönen, welche beim Nachchromieren blau, beim Nachkupfern blauviolett und echt werden. Claim: Process for the preparation of a new azo dye, characterized in that 1-oxynaphtha-lin-4,8-disulfamide is coupled with dianotated 1-oxynaphtha-lin-2-amino-8-sulphamide-4-sulfonic acid. The new dye forms a dark powder and dyes wool in the acetic acid bath in red-violet shades, which become blue when chromium plating and blue-violet and real when copper plating.
