Description

  

  Verfahren zur     fferstelluug    eines     neueu        Azofarbstoffes.       Es wurde gefunden, dass man einen neuen       Azofarbstoff    herstellen kann, wenn man  das     4,4'-Dioxydinaphtyl-1,1'-keton    mit     dia,zo-          tiertem    o     Toluidin    kuppelt. Der neue Farb  stoff bildet ein in Wasser unlösliches, dunkel  rotes Pulver; auf geeigneter Unterlage her  gestellt, erzeugt er rote Töne.  



  <I>Beispiel:</I>  31,4 Teile     4,4'-Dioxydinaphtyl-1,1'-keton     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 10,4 Teilen     o-Toluidin    berei-         teten        Diazolösung.    Der gebildete Farbstoff  scheidet sich sofort als roter 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 4,4'-dioxydinaphthyl-1,1'-ketone is coupled with dia, zotierten o toluidine. The new dye forms a dark red powder that is insoluble in water; When placed on a suitable surface, it produces red tones.



  <I> Example: </I> 31.4 parts of 4,4'-dioxydinaphthyl-1,1'-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 10.4 parts of o-toluidine is added. The dye formed separates out immediately as a red precipitate.
