Description

  

  Verfahren zur Darstellung eines     o-Oxymonoazofarbstoffes.       Im Hauptpatent wurde die Darstellung  eines Farbstoffes beschrieben, der mit Hilfe  von Chrombeizen auf Wolle olive farbige  Töne von hervorragender Wasch-; Walk-.       Potting-    und Lichtechtheit erzeugt. Der Farb  stoff     wird    dargestellt durch     Kupplung    von  dianotierter     Piliraminsäure    mit     4-Acetyl-          aminophenol.     



  In diesem Verfahren lässt sich mit glei  chem Erfolg das     4-Acetylaminopheriol    durch  1. -     DZethyl-3-formylamino-4-oxybenzol    erset  zen.  



       Beispiel:     19,9 Teile     Pikraminsäure    werden, wie  üblich, dianotiert und mit einer     sodaalkali-          schen    Lösung von 15,1 Teilen     1-Methyl-3-          formylamino-4-oxybenzol        vereinigt.    Der fer  tig gebildete Farbstoff wird     ausgesalzen    und       abgepresst.    Er bildet getrocknet ein schwärz-         liches    Pulver, das sich in heissem Wasser  orange löst.



  Process for the preparation of an o-oxymonoazo dye. In the main patent, the representation of a dye was described, with the help of chrome stains on wool olive tones of excellent washing; Walk-. Potting and lightfastness generated. The dye is produced by coupling dianotated piliramic acid with 4-acetylaminophenol.



  In this process, the 4-acetylaminopheriol can be replaced by 1.-DZethyl-3-formylamino-4-oxybenzene with the same success.



       Example: 19.9 parts of picric acid are dianotized as usual and combined with a soda-alkaline solution of 15.1 parts of 1-methyl-3-formylamino-4-oxybenzene. The finished dye is salted out and pressed out. When dried, it forms a blackish powder that dissolves orange in hot water.
