Description

  

      Verfahren    zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen       Azofarbstoff    erhält, wenn man das 2     #        3-Oxy-          naphthoesäureanilid    mit dianotiertem     4-Chlor-          2-äminodiphenyläthei-        kuppelt.    Der neue Farb  stoff bildet ein in Wasser unlösliches, dunkel  rotes Pulver; auf der Faser oder einem geeig  neten Substrat hergestellt, erzeugt er feurige  Scharlachtöne.  



  <I>Beispiel:</I>  26,3 Teile 2     #        3-Oxynaphthoesäureanilid     werden in 500 Teilen Wasser unter Zusatz  vor. 4 Teilen     Ätznatron    gelöst. Hierauf fügt  man noch 20 Teile Soda hinzu und versetzt  mit einer aus 22,9 Teilen     4-Chlor-2-amino=          diphenyläther    bereiteten     Diazolösung.    Der    gebildete     Farbstoff    scheidet sich sofort als  hochroter Niederschlag aus.



      Process for the production of a new azo dye. It has been found that a new azo dye is obtained if the 2 # 3-oxynaphthoic anilide is coupled with dianotated 4-chloro-2-aminodiphenyleth- ylethane. The new dye forms a dark red powder that is insoluble in water; Produced on the fiber or a suitable substrate, it produces fiery scarlet tones.



  <I> Example: </I> 26.3 parts of 2 # 3-oxynaphthoic anilide are added to 500 parts of water. 4 parts of caustic soda dissolved. 20 parts of soda are then added and a diazo solution prepared from 22.9 parts of 4-chloro-2-amino = diphenyl ether is added. The dye formed separates out immediately as a crimson precipitate.
