Description

  

  Verfahren zur Darstellung eines     Dianthrachinonylamins    der     Anthrachinonakridonreihe.       Im Hauptpatent ist ein Verfahren zur       Herstellung    eines     Dianthrachinonylamins    der       Anthrachinonakridonreihe    beschrieben, das  dadurch gekennzeichnet ist, dass man auf       Trichloranthrachinonakridon,

      erhältlich durch  Chlorieren von     Anthrachinon-1.2-akridon    in  Nitrobenzol     1-Benzoylamino    - 5 -     aminoanthra-          chinon    in Gegenwart eines säurebindenden  Mittels und eines     Katalysators    in einem  hochsiedenden Lösungsmittel einwirken lässt.  



  Gegenstand vorliegender Erfindung ist  nun ein Verfahren zur Darstellung eines     Di-          anthrachinonylamins    der     Anthrachinonakridon-          reihe,    dadurch gekennzeichnet; dass man auf       Trichloranthrachinonakridon,    erhältlich durch  Chlorieren von     Anthrachinon-1        .2-akridon    in  Nitrobenzol,     1-Benzoylamino-4-aminoanthra-          chinon    in Gegenwart eines säurebindenden  Mittels und eines     Katalysators,    in einem  hochsiedenden Lösungsmittel einwirken lässt.

    <I>Beispiel:</I>  10 Gewichtsteile Trichloranthrachinon-         akridon,    erhältlich durch Chlorieren von       Antbrachinon-1.2-akridon    in Nitrobenzol,  werden mit 8 Gewichtsteilen     1-Benzoyl-          amino-4-aminoanthrachinon    in U     egenwart    von  4 Gewichtsteilen     Natriumacetat    und 0,2 Ge  wichtsteilen Kupferchlorid in 200 Gewichts  teilen- Naphtalin zum Sieden erhitzt. Das  Kondensationsprodukt scheidet sich in dunkeln  Kristallen ab und wird in üblicher Weise,  gegebenenfalls unter Zusatz     eitles    Verdün  nungsmittels aufgearbeitet. Es löst sich in  Schwefelsäure gelboliv.  



  Die Ausfärbung des Produktes auf Baum  wolle ist grau. Ausser als     Küpenfarbstoff     kann es auch als Zwischenprodukt für die  Herstellung weiterer     Farbstoffe    dienen.



  Process for the preparation of a dianthraquinonylamine of the anthraquinone acridone series. The main patent describes a process for the preparation of a dianthraquinonylamine of the anthraquinone acridone series, which is characterized in that trichloroanthraquinone acridone,

      obtainable by chlorination of anthraquinone-1,2-acridone in nitrobenzene 1-benzoylamino - 5 - aminoanthraquinone in the presence of an acid-binding agent and a catalyst in a high-boiling solvent.



  The present invention now relates to a process for the preparation of a dianthraquinonylamine of the anthraquinone acridone series, characterized in that; that on trichloroanthraquinone acridone, obtainable by chlorinating anthraquinone-1,2-acridone in nitrobenzene, 1-benzoylamino-4-aminoanthraquinone in the presence of an acid-binding agent and a catalyst, is allowed to act in a high-boiling solvent.

    <I> Example: </I> 10 parts by weight of trichloroanthraquinone acridone, obtainable by chlorinating antrachinone-1,2-acridone in nitrobenzene, are mixed with 8 parts by weight of 1-benzoylamino-4-aminoanthraquinone in the presence of 4 parts by weight of sodium acetate and 0, 2 parts by weight of copper chloride in 200 parts by weight of naphthalene heated to the boil. The condensation product separates out in dark crystals and is worked up in the customary manner, optionally with the addition of diluent diluents. It dissolves yellow-olive in sulfuric acid.



  The color of the product on cotton is gray. In addition to being used as a vat dye, it can also be used as an intermediate for the production of other dyes.
