Description

  

  Verfahren zur Darstellung eines     o-Ogymonoazofarbstoffes.       Im Hauptpatent wurde die Darstellung       eines    Farbstoffes beschrieben, der mit Hilfe  von Chrombeizen auf Wolle     olivefarbige     Töne von hervorragender Wasch-, Walk-,       Potting-.    und Lichtechtheit erzeugt. Der  Farbstoff wird dargestellt durch Kupplung  von dianotierter     Pikraminsäure    mit     4-Acetyl-          amionphenol.     



  In diesem Verfahren     lässt    sich mit glei  chem Erfolge das     4-Acetylaminophenol    durch       1-Methyl-3-acetylamino-4-oxybenzol    ersetzen.  <I>Beispiel:</I>  19,9 Teile     Pikraminsäure    werden wie üb  lich .dianotiert und mit einer     sodaalkalischen     Lösung von 16,5 Teilen     1-Methyl-3-acetyl-          amino-4-oxybenzol        vereinigt.    Der fertig ge  bildete Farbstoff wird     ausgesalzen        und    ab  gepresst. Er bildet getrocknet ein schwärz-         liches    Pulver, das sich in heissem Wasser  orange löst.



  Process for the preparation of an o-ogymonoazo dye. In the main patent, the representation of a dye was described, which with the help of chrome stains on wool olive tones of excellent washing, fulling, potting. and produces lightfastness. The dye is produced by coupling dianotated picric acid with 4-acetylamionphenol.



  In this process, the 4-acetylaminophenol can be replaced by 1-methyl-3-acetylamino-4-oxybenzene with the same success. <I> Example: </I> 19.9 parts of picric acid are dianotized as usual and combined with a soda-alkaline solution of 16.5 parts of 1-methyl-3-acetylamino-4-oxybenzene. The finished dyestuff is salted out and pressed off. When dried, it forms a blackish powder that dissolves orange in hot water.

PATENTANSPRUCH: Verfahren zur Darstellung eines Wolle mit Hilfe von Chrombeize olive färbenden o Oxymonoazofarbstoffes, dadurch gekennzeich net, dass man dianotierte Pikraminsäure mit 1-Methyl-3-acetylamino-4-oxybenzol kuppelt. Der Farbstoff bildet getrocknet ein schwärzliches Pulver, das sich in heissem Wasser orange löst; seine Färbungen sind von hervorragender Wasch-, Walk-, Potting- und Lichtechtheit. PATENT CLAIM: Process for the production of wool with the aid of chrome stain olive-coloring o oxymonoazo dye, characterized in that dianotated picric acid is coupled with 1-methyl-3-acetylamino-4-oxybenzene. When dried, the dye forms a blackish powder that dissolves orange in hot water; its dyeings are extremely fast to washing, fulling, potting and light.
