Description

  

      Zusatzpatent    zum Hauptpatent Nr. 103649.    verfahren zur Herstellung eines     indigoiden    Farbstoffes der     Anthracenreihe.       Es wurde gefunden, dass man einen     indi-          goiden    Farbstoff der     Anthracenreihe    erhält.  wenn man ein     Anil    des     2,3-Anthrachinon-          thioisatins    mit     2,3-Anthrachinonindoxyl    kon  densiert.

   Der Farbstoff bildet ein blau  schwarzes,     bronzierendes    Pulver, das sich in  Schwefelsäure mit grüner Farbe löst und  eine Braunolive     Küpe    gibt, aus welcher  Baumwolle blaugrün gefärbt wird.    <I>. Beispiel</I>  20,5 Teile des     p-Dimethylaminoanils    des       Z,3-Anthrachinonthioisatins    werden mit     .13,5     Teilen     2,3-Anthrachinonindoxyl    und 500 Tei  len     Pyridin    oder     Trichlorbenzol-zwei    Stunden  unter     Rückfluss    gekocht. Der ausgeschie  dene Farbstoff wird abgesaugt, gewaschen  und getrocknet.  



  Die Reaktion verläuft nach folgender

      Additional patent to main patent no. 103649. Process for the production of an indigoid dye of the anthracene series. It has been found that an indigoid dye of the anthracene series is obtained. if an anil of 2,3-anthraquinone thioisatin is condensed with 2,3-anthraquinone indoxyl.

   The dye forms a blue-black, bronzing powder, which dissolves in sulfuric acid with a green color and gives a brown olive vat from which cotton is dyed blue-green. <I>. EXAMPLE 20.5 parts of the p-dimethylaminoanil of Z, 3-anthraquinone thioisatin are refluxed for two hours with 13.5 parts of 2,3-anthraquinone indoxyl and 500 parts of pyridine or trichlorobenzene. The excreted dye is filtered off with suction, washed and dried.



  The reaction proceeds as follows
