Description

  

  Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen       Azofarbstoff    herstellen kann, wenn man  das     4-Oxynaphtalin-l-phenylketon    mit     tetra-          zotiertem        Dianisidin    kuppelt. Der neue     I'arb-          stoff    bildet ein in Wasser unlösliches, blau  sehwarzes Pulver; auf geeigneter Unterlage       hergestellt,    erzeugt er     violettbläue    Töne.  



  <I>Beispiel:</I>  <B><U>93,8</U></B> Teile     4-Oxynaphtalin-l-phenyllzeton     werden in     500    Teilen Wasser unter Zusatz  von 4 Teilen     Ätznatron    gelöst. Hierauf fügt  man noch 20 Teile     Soda    hinzu und versetzt  mit einer aus 12,2 Teilen     Dianisidin    bereite  ten     Tetrazolösung.    Der gebildete Farbstoff    scheidet sich sofort als braunvioletter Nie  derschlag aus.



  Process for the production of a new azo dye. It has been found that a new azo dye can be produced by coupling the 4-oxynaphthalene-1-phenyl ketone with tetrazotized dianisidine. The new carbon forms a water-insoluble, blue-black powder; Produced on a suitable surface, it produces violet-blue tones.



  <I> Example: </I> <B><U>93,8</U> </B> Parts of 4-oxynaphthalene-1-phenyltone 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 tetrazo solution prepared from 12.2 parts of dianisidine is added. The dye formed is immediately precipitated as a brownish-violet precipitate.
