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-Anthraaen-          thiaisatins    mit     Oxythionaphthenkarbonsäure          kondensiert.    Der Farbstoff bildet ein grün  schwarzes Pulver,

   das sich in Schwefel  säure mit brauner Farbe löst und eine     vio-          lettbraune        Küpe        gibt;    aus welcher Baum  wolle grün gefärbt wird.    <I>Beispiel</I>  19 Teile des     p-Dimethylämi.noanils    des       2,3-Anthra;centhioisatins    werden mit 10 Tei  len     Oxythionaphthenkarbonsäure    und 500  Teilen     Pyridin    oder     Trichlorbenzol    zwei  Stunden unter     Rückfluss    gekocht. Der aus  geschiedene     Farbsto-ff        wird        abgesaugt,    ge  waschen und getrocknet.

    



  Die Reaktion verläuft nach folgender       Gleichunz:     
EMI0001.0026     




  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-anthracene thiaizatin is condensed with oxythionaphthene carboxylic acid. The dye forms a green black powder,

   which dissolves in sulfuric acid with a brown color and gives a violet brown vat; which tree wool is colored green. <I> Example </I> 19 parts of p-Dimethylämi.noanil des 2,3-Anthra; centhioisatins are refluxed with 10 parts of oxythionaphthenecarboxylic acid and 500 parts of pyridine or trichlorobenzene for two hours. The separated dye is filtered off with suction, washed and dried.

    



  The reaction proceeds according to the following equation:
