Description

  

      Zusatzpatent    zum Hauptpatent Nr. 101614.    Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen       Azofarbstoff    erhält, wenn man das     2-Oxy-          naphthalin-6-sulfamid    mit     diazotierter        1-Oxy-          naphthalin    - 2 -     a,mino-8-sulfamicl-4-sulfosäura     kuppelt. Der neue Farbstoff bildet ein dunk  les Pulver und färbt Wolle im essigsauren  Bade in blauroten Farbtönen, welche beim       Nachchromieren    hellblau, beim Nachkupfern  rotviolett und echt werden.

      <I>Beispiel:</I>  22,3 Teile     2-Oxynaphthalin-6-sulfamid     werden in eine Lösung von 56 Teilen     Ätzkali     in 48 Teilen Wasser bei 40-45   eingetra  gen. Die so erhaltene Mischung wird hierauf  mit der     Diazoverbindung    aus 31,8 Teilen     1-          Oxynaphthalin-2-amino-8-sulfamid    - 4 -     sul.fo-          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 gebildeten Farbstoff aus.



      Additional patent to main patent no. 101614. Process for the production of a new azo dye. It has been found that a new azo dye is obtained when 2-oxynaphthalene-6-sulfamide is coupled with diazotized 1-oxynaphthalene-2-a, mino-8-sulfamicl-4-sulfosacid. The new dye forms a dark powder and dyes wool in the acetic acid bath in blue-red shades, which become light blue when chromium plating and red-violet and real when copper plating.

      <I> Example: </I> 22.3 parts of 2-oxynaphthalene-6-sulfamide are introduced into a solution of 56 parts of caustic potash in 48 parts of water at 40-45. The mixture thus obtained is then mixed with the diazo compound from 31 , 8 parts of 1-oxynaphthalene-2-amino-8-sulfamide - 4 - sulpho acid added in the form of a 49% paste. After coupling has ended, the mixture is diluted with 200 parts of cold water, 280 parts of 15% strength hydrochloric acid are run in with stirring and the dyestuff formed is salted out.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Alzofarbstoffes, dadurch gekennzeichnet, dass man das 2-Oxynaphthalin-6-sulfamid mit di- azotierter 1-Oxynaphthalin-2-a@mino-8-sulfa- micl-4-sulfosäure kuppelt. Der neue Farbstoff bildet ein dunkles Pulver und färbt Wolle im essigsauren Bade in blauroten Farbtönen, welche beim Nachchromieren hellblau, beim Nachkupfern rotviolett und echt werden. PATENT CLAIM: Process for the production of a new alzo dye, characterized in that the 2-oxynaphthalene-6-sulfamide is coupled with diazoated 1-oxynaphthalene-2-a @ mino-8-sulfamicl-4-sulfonic acid. The new dye forms a dark powder and dyes wool in the acetic acid bath in blue-red shades, which become light blue when chroming and red-violet and real when coppering.
