Description

  

  Verfahren zur Darstellung eines     o-Ogyazofarbstoffes.       Es wurde gefunden, dass durch Kuppeln  von 3     #        4.#        6-Trichlor-2-diazo-l-oxybenzol    mit       1-Acetylamino-8-oxy        iaphtalin-4-sulfosäure    ein       Farbstoff    erhalten wird, der auf Wolle mit  Chrombeizen klare blaue, gleichmässige walk-,  licht- und reibechte Nuancen liefert.  



  <I>Beispiel:</I>  Die aus 21,3 Teilen 3     #    4     #        6-Trichlor-2-          amino-l-oxybenzol    bereitete     Diazoverbindung     wird mit 28,1 Teilen     1-Acetylamino-8-oxy-          naphtalin-4-sulfosäure    in     sodaalkalischer    Lö  sung vereinigt. Nach     beendeter    Kupplung  wird der     Farbstoff    in der üblichen Weise  aufgearbeitet.



  Process for the preparation of an o-ogyazo dye. It was found that by coupling 3 # 4. # 6-trichloro-2-diazo-1-oxybenzene with 1-acetylamino-8-oxyiaphthalene-4-sulfonic acid, a dye is obtained which on wool with chrome stains gives clear blue, delivers evenly milled, lightfast and rubfast nuances.



  <I> Example: </I> The diazo compound prepared from 21.3 parts of 3 # 4 # 6-trichloro-2-amino-1-oxybenzene is mixed with 28.1 parts of 1-acetylamino-8-oxynaphthalene-4- sulfonic acid combined in soda-alkaline solution. After the coupling has ended, the dye is worked up in the customary manner.
