Description

  

  Verfahren zur Herstellung eines     bionoazofarbstoffes.            Vorliegendes    Patent bezieht sich auf ein       Verfahren    zur     Hemstellung    eines     Monoazo-          farbstoffes,,,dadurch        .gek        enuzeiehnet"dass    man       diazotiertes        5-Nitro-4-chlor-2-aminophenol    in       sodaalkalischer    Lösung mit     1-Benzoylamino-          6-ogynaphthalin-3-sulfonsäure    kuppelt.  



       Der    so erhaltene     Farbstoff        ist    ein dunkles  Pulver     und    färbt     Wolle    in roten Tönen. Beim       Chromgeren    erhält man blaugraue Färbungen  von     wertvollen        Echtheitseigenschaften.     



  <I>Beispiel:</I>  Eine     aus    18,9 Teilen     5-Nitro-4-chlor-2-          aminophenol    in der     üblichen        Weise        herge-          stellte        Diazolösung    wird mit einer überschüs  siges     Natriumcarbonat    enthaltenden Lösung  von 35 Teilen 1 Benzoylamino-6-oxynaph-         thalin-3-sulfons,äure    vereinigt. Nach beende  ter     Kuppelung        wird    der gebildete Farbstoff  abgeschieden     und        getrocknet.  



  Process for the preparation of a bionoazo dye. The present patent relates to a process for the preparation of a monoazo dye ,,, thereby .gek enuzeiehnet "that one diazotized 5-nitro-4-chloro-2-aminophenol in soda-alkaline solution with 1-benzoylamino-6-ogynaphthalene-3-sulfonic acid clutch.



       The dye thus obtained is a dark powder and dyes wool in red tones. In the case of Chromgeren, blue-gray colorations with valuable fastness properties are obtained.



  <I> Example: </I> A diazo solution prepared in the usual way from 18.9 parts of 5-nitro-4-chloro-2-aminophenol is mixed with a solution of 35 parts of 1 benzoylamino-6- containing excess sodium carbonate. oxynaphthalene-3-sulfone, acid combined. After the coupling has ended, the dye formed is deposited and dried.
