  Verfahren zur Herstellung eines     indigoiden        Farbstoffes    der     Anthracenreihe.       Es wurde gefunden, dass man einen neuen       indigoiden    Farbstoff der     Anthracenreihe    er  hält, wenn man das     Anthra,c.enderivat,    das  durch Behandeln der     Anthrachinon-2-glyzin-          3-ka,rbonsäure    mit     Kondensutionsmitteln    ent  steht, mit     Acenaphthenchinon    kondensiert.

    Der neue Farbstoff bildet ein dunkelblaues,  kristallinisches Pulver, das sich in Schwefel  säure mit     leuchtend    grünblauer Farbe, in hei  ssem Nitrobenzol schwer mit weinroter Farbe  löst. Mit     Hydrosulfit    und Natronlauge wird  eine     braunroto        Küpe    gebildet, aus welcher  Baumwolle in sehr echten, rotblauen Farb  tönen gefärbt wird.

           Beispiel:       17 Teile des     Anthracenderivates,    das  durch Behandeln der     Anthrachinon-2-glyzin-          3-karbonsäure    mit Kondensationsmitteln er  halten wird, werden zusammen mit. 10 Teilen       Acenaphthenchinon,    3 Teilen Schwefelsäure  monohydrat und 150 Teilen Eisessig am       Rückflusskühler    ,gekocht. Nach kurzer Zeit  setzt die     Abscheidung    eines blauvioletten,    kristallinischen Kondensationsproduktes ein.  Wenn die Reaktion beendet ist, wird abge  kühlt, filtriert und der Rückstand gewaschen  und getrocknet.



  Process for the production of an indigoid dye of the anthracene series. It has been found that a new indigoid dye of the anthracene series is obtained if the anthra, c.enderivat, which is produced by treating the anthraquinone-2-glycine-3-ca, rboxylic acid with condensation agents, is condensed with acenaphthenquinone.

    The new dye forms a dark blue, crystalline powder that dissolves in sulfuric acid with a bright green-blue color, in hot nitrobenzene with difficulty dissolving it with a wine-red color. With hydrosulphite and caustic soda, a brown-red vat is formed from which cotton is dyed in very real, red-blue hues.

           Example: 17 parts of the anthracene derivative that is obtained by treating the anthraquinone-2-glycine-3-carboxylic acid with condensation agents are used together with. 10 parts of acenaphthenquinone, 3 parts of sulfuric acid monohydrate and 150 parts of glacial acetic acid on a reflux condenser, boiled. After a short time, a blue-violet, crystalline condensation product begins to separate. When the reaction has ended, it is cooled, filtered and the residue washed and dried.
