      'litsatzpatetit    zum Hauptpatent Nr. 163539.    Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen       Azofarbstof    erhält, wenn     inan    dianotiertes       4-Nitro-2-niethoxy-l-airiinobenzol    mit     Äthyl-          (co-acetoxäthyl)-ariilin    vereinigt.  



  Der neue Farbstoff bildet ein dunkelrotes       Pulver,    das in Wasser unlöslich ist, sich da  gegen in Essigester leicht mit roter Farbe  löst. Er färbt     Acetatseide    in roten Tönen.  <I>Beispiel:</I>  16,8 Teile     4-Nitro-2-inethoxy-l-aininoberi-          zol    werden mit Wasser vermahlen und mit  25 Teilen konzentrierter Salzsäure und 7 Teilen       Natriumnitrit    unter Zusatz von Eis dianotiert.  Die erhaltene     Diazolösung    lässt     nian    zu einer  Lösung von 20,7     TeilenÄthyl-(cu-acetoxäthyl)-          anilin    in     verdünnter    Salzsäure zufliessen.

      Darin versetzt man langsam mit Natrium  acetatlösung, bis die     Kupplung    beendet ist.  Der Farbstoff scheidet sich als dunkelrotes  Pulver aus.



      'litsatzpatetit for main patent no. 163539. Process for the production of a new azo dye. It has been found that a new azo dye is obtained when inane dianotized 4-nitro-2-niethoxy-1-aerinobenzene is combined with ethyl- (co-acetoxethyl) -ariiline.



  The new dye forms a dark red powder that is insoluble in water, whereas it dissolves easily with a red color in ethyl acetate. He dyes acetate silk in red tones. <I> Example: </I> 16.8 parts of 4-nitro-2-ynethoxy-1-aininoberizole are ground with water and dianotized with 25 parts of concentrated hydrochloric acid and 7 parts of sodium nitrite with the addition of ice. The diazo solution obtained is allowed to flow into a solution of 20.7 parts of ethyl (cu-acetoxyethyl) aniline in dilute hydrochloric acid.

      Sodium acetate solution is slowly added until the coupling has ended. The dye separates out as a dark red powder.
