Description

  

      Verfahren    zur Herstellung eines     indigoiden        Farbstoffes    der     Anthraehinonreihe.            Vorliegendes    Patent bezieht sich auf ein  Verfahren zur     Herstellung    eines     indigoiden     Farbstoffes der     Anthrachinonreihe,    dadurch  gekennzeichnet, dass man     9-Chlor-a-naphtisa-          tin    mit     Anthrachinon-1    .     2-oxythiophen    kon  densiert.  



  Das dunkle Pulver löst sich in konzen  trierter Schwefelsäure mit brauner Farbe  und färbt Baumwolle aus gelbbrauner     Küpe     in     gelboliven    Tönen an.  



  <I>Beispiel:</I>  60 Teile     9-Chlor-a-naphtisatin    werden  mit 70 Teilen     Anthrachinon-7..2-oxythio-          phen    in etwa 2000 Teilen Eisessig gut ver  iührt und nach Zugabe von 5 Teilen kon-    zentrierter Salzsäure     etwa    5     Stunden    zum  Sieden erhitzt. Der Farbstoff     wird    abgesaugt  und getrocknet.



      Process for the production of an indigoid dye of the anthraquinone series. The present patent relates to a process for the production of an indigoid dye of the anthraquinone series, characterized in that 9-chloro-a-naphthatizin is mixed with anthraquinone-1. 2-oxythiophene condenses.



  The dark powder dissolves in concentrated sulfuric acid with a brown color and stains cotton from a yellow-brown vat in yellow-olive tones.



  <I> Example: </I> 60 parts of 9-chloro-a-naphtisatin are mixed well with 70 parts of anthraquinone-7..2-oxythiophene in about 2000 parts of glacial acetic acid and, after addition of 5 parts of concentrated hydrochloric acid heated to the boil for about 5 hours. The dye is filtered off with suction and dried.
