Description

  

  Verfahren zur Darstellung eines     wertvollen        Küpenfarbstoffes.       Im Hauptpatent ist ein Verfahren zur  Darstellung eines wertvollen     Küpenfarbstoffes     beschrieben, bei dem     Aminodibenzanthron,     das erhalten werden kann durch Reduktion  des durch Nitrieren von     Dibenzanthron    ent  stehenden     Mononitrodibenzanthrons,    mit einem  in     1-Stellung    negativ substituierten     Anthra-          chinon    kondensiert wird.  



  Es wurde nun gefunden, dass man einen  ähnlichen wertvollen     Küpenfarbstoff    erhält,  wenn man 2     Mol.        Aminodibenzanthron,    das  erhalten werden kann durch Reduktion des  durch Nitrieren von     Dibenzanthron    entste  henden     Mononitrodibenzanthrons,    mit 1     Mol.          Trichloranthrachinonacridon    das durch direkte       Ühlorierung    von     Anthrachinonacridon    erhalten  werden kann, kondensiert. Die Kondensation  führt man zweckmässig in hochsiedenden       Lösungs-    oder Verdünnungsmitteln aus, und  man kann hierbei auch säurebindende Mittel  zusetzen.

   Vielfach ist die Anwendung von  Katalysatoren vorteilhaft, als welche beispiels-    weise Gemische von     Natriumacetat    und  Kupfersalzen benutzt werden können.  



  Der neue     Küpenfarbstoff    ist ein schwarzes  Pulver; er ist in konzentrierter Schwefelsäure  mit violetter Farbe löslich und färbt Baum  wolle aus blauer     Küpe    in schwarzen, her  vorragend echten Tönen.  



  <I>Beispiel:</I>  47 Teile des     Aminodibenzanthrons,    21  Teile     Trichloranthrachinonacridort,    20 Teile       Natriumacetat    und 2,5 Teile Kupferkarbonat  werden in 1000 Teilen Nitrobenzol 20 Stun  den lang unter Rühren gekocht und wie  üblich aufgearbeitet.  



  Man kann das     Aminodibenzanthron    wäh  rend der Reaktion, aus der entsprechenden  Nitroverbindung und einem Reduktionsmittel,  z. B.     Hydrazinhydrat    oder Schwefel erzeugen.



  Process for the preparation of a valuable vat dye. The main patent describes a process for the preparation of a valuable vat dye in which aminodibenzanthrone, which can be obtained by reducing the mononitrodibenzanthrone produced by nitrating dibenzanthrone, is condensed with an anthraquinone negatively substituted in the 1-position.



  It has now been found that a similar valuable vat dye is obtained if 2 moles of aminodibenzanthrone, which can be obtained by reducing the mononitrodibenzanthrone formed by nitrating dibenzanthrone, with 1 mole of trichloroanthraquinone acridone which can be obtained by direct chlorination of anthraquinone acridone, condensed. The condensation is expediently carried out in high-boiling solvents or diluents, and acid-binding agents can also be added.

   In many cases it is advantageous to use catalysts as, for example, mixtures of sodium acetate and copper salts can be used.



  The new vat dye is a black powder; it is soluble in concentrated sulfuric acid with a violet color and dyes cotton from a blue vat in black, exceptionally genuine shades.



  <I> Example: </I> 47 parts of aminodibenzanthrone, 21 parts of trichloroanthraquinone acridort, 20 parts of sodium acetate and 2.5 parts of copper carbonate are boiled in 1000 parts of nitrobenzene for 20 hours with stirring and worked up as usual.



  The aminodibenzanthrone can be used during the reaction from the corresponding nitro compound and a reducing agent, e.g. B. produce hydrazine hydrate or sulfur.
