Description

  

  Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen       Azofarbstoff    herstellen kann, wenn man das       4-OYynaplitalin-l-pheriylketon    mit     diazotier-          tem        4-Chlor-2-aininodiphenyläther    kuppelt.  Der neue F     arbstoff    bildet ein in Wasser un  lösliches, dunkelrotes Pulver; auf geeigneter  Unterlabe hergestellt,     erzeugt    er feurige       Scharlachtöne.     



  <I>Beispiel:</I>  28,8 Teile     4-Oxynaphtalin-1-plienylketon     werden in 500 Teilen Wasser unter Zusatz  von 4 Teilen     Ätznatron    gelöst.     Hierauf    fügt  man noch 20 Teile Soda hinzu und ver  setzt mit einer aus 22,9 Teilen 4-Chlor-2-         aminodiphenyläther    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 can be produced if the 4-OYynaplitalin-1-pheriyl ketone is coupled with diazotized 4-chloro-2-ainodiphenyl ether. The new dye forms a dark red powder which is insoluble in water; Produced on a suitable substrate, it produces fiery scarlet tones.



  <I> Example: </I> 28.8 parts of 4-oxynaphthalene-1-plienyl ketone are dissolved in 500 parts of water with the addition of 4 parts of caustic soda. 20 parts of soda are then added and a diazo solution prepared from 22.9 parts of 4-chloro-2-aminodiphenyl ether is added. The dye formed separates out immediately as a crimson precipitate.
