Description

  

  Verfahren zur Herstellung eines     indigoiden        Farbstoffes    der     Anthracenreihe.       Es wurde gefunden, dass man einen     in-          digoiden    Farbstoff der     Anthracenreihe    erhält.

    wenn man ein     Anil    des     2,3-Anthracen-          thioisatins    mit     2,3-Anthrachinonoxythiophen          l@ondensiert.    Der Farbstoff bildet ein grünes  Pulver, das sich in Schwefelsäure mit oliver  Farbe löst und eine Braunolive     Küpe    gibt,       a        a        us        welcher        Baumwolle        grün        gefärbt        wird.

  imethylaminoanils    des       2,3-Anthracenthioisatins    werden mit 14,5  Teilen     2,3-Anthrachinonoxythiophen    und 500  Teilen     Pyridin    oder     Trichlorbenzol    zwei  Stunden unter     Rückfluss    gekocht. Der aus  geschiedene Farbstoff wird abgesaugt, ge  waschen und getrocknet.  



  Die Reaktion verläuft nach folgender  Gleichung



  Process for the production of an indigoid dye of the anthracene series. It has been found that an indigo dye of the anthracene series is obtained.

    if an anil of 2,3-anthracenthioisatin is ondensated with 2,3-anthraquinone oxythiophene. The dye forms a green powder which dissolves in sulfuric acid with an olive color and gives a brown olive vat from which cotton is dyed green.
EMI0001.0021
    <I> Example </I> 19 parts of p-1)

  imethylaminoanils of 2,3-anthracenthioisatins are refluxed for two hours with 14.5 parts of 2,3-anthraquinone oxythiophene and 500 parts of pyridine or trichlorobenzene. The separated dye is filtered off, washed and dried.



  The reaction proceeds according to the following equation
