  Verfahren zur Darstellung eines wertvollen     Küpenfarbstof%s.       Im     Ilauptpatent    ist ein Verfahren zur  Darstellung eines wertvollen     Küpenfarb-          stoffes    beschrieben, bei dem     Aminodibenz-          anthron,    das     erhalten    werden kann .durch  Reduktion des durch Nitrieren von     Di-          benza.nthron    entstehenden     Mononitrodibenz-          anthrons,    mit einem in     1-Stellung    negativ  substituierten     Anthra.chinon    kondensiert  wird.  



  Es wurde nun gefunden,     .dass    man einen  ähnlichen wertvollen     Küpenfarbstoff    erhält,  wenn man 3     Mol.        Aminodibenzanthron,    das  erhalten werden kann durch Reduktion des  durch Nitrieren von     Dibenzanthron    entstehen  den     Mononitrodibenzanthrons,    mit 1     Mol.        Tri-          lialogen-ms-naphto,dianthron,    hergestellt .aus       Trihalogen-ms-benzdianthron,    das durch di  rekte     Halogenierung    von     ms-Benzdianthron     erhalten wird,

   durch     Verbacken    mit Alumi  niumchlorid oder durch     Oxydation    mit       hraunstein    in Gegenwart von Schwefelsäure,  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 Katalysa  toren vorteilhaft,     .als    welche beispielsweise  Gemische von     Natriumacetat    und Kupfersal  zen benutzt     werden.    können.  



  Der neue     Küpenàrbstoff        ist    ein schwar  zes Pulver; er ist in konzentrierter .Schwefel  säure mit violetter Farbe löslich und färbt  Baumwolle aus blauer     Küpe    in schwarzen,  hervorragend echten Tönen.  



  <I>Beispiel:</I>  Man suspendiert 47 Teile des     Amino-          dibenzanthrons    in 100 Teilen Nitrobenzol,  gibt 15 Teile     Natriumacetat,    3 Teile Kup  feroxyd und 21 Teile     Tribrom-ms-naphto-          dianthron    (dargestellt ;aus     Tribrom-ms-benz-          dianthron    durch     Verbacken    mit Aluminium  chlorid) hinzu, worauf man unter Rühren bis  zur Beendigung der     Farbstoffbildung    kocht.  Darauf wird wie üblich aufgearbeitet.

        Man kann .das     Aminodibenzanthron    wäh  rend     ,der    Reaktion, aus der entsprechenden  Nitroverbindung und einem Reduktionsmit  tel, zum Beispiel     Hydrazinhydrat    oder       Schwefel    erzeugen.     ,Statt    des     Tribrom-ms-          naphto,dianthrons    kann man .auch     Trichlor-          ms-naphtodianthron    verwenden.



  Method for the preparation of a valuable vat dye The main patent describes a process for the preparation of a valuable vat dye, with the aminodibenzanthrone, which can be obtained by reducing the mononitrodibenzanthrone produced by nitrating dibenza.nthrone, with an anthra that is negatively substituted in the 1-position .quinone is condensed.



  It has now been found that a similar valuable vat dye is obtained if 3 moles of aminodibenzanthrone, which can be obtained by reducing the mononitrodibenzanthrone formed by nitrating dibenzanthrone, with 1 mole of trilialogen-ms-naphto, dianthrone, manufactured from trihalogen ms-benzdianthrone, which is obtained by direct halogenation of ms-benzdianthrone,

   by baking with aluminum chloride or by oxidation with ruthenium in the presence of sulfuric acid. The condensation is expediently carried out in high-boiling solvents or diluents, and acid-binding agents can also be added. In many cases, the use of catalysts is advantageous, as which, for example, mixtures of sodium acetate and copper salts are used. can.



  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, outstandingly real shades.



  <I> Example: </I> 47 parts of aminodibenzanthrone are suspended in 100 parts of nitrobenzene, 15 parts of sodium acetate, 3 parts of copper oxide and 21 parts of tribromine-ms-naphthodianthrone (shown; from tribromine-ms-benz - Dianthron by baking with aluminum chloride), whereupon the mixture is boiled while stirring until the dye has formed. This is worked up as usual.

        You can generate the aminodibenzanthrone during the reaction from the corresponding nitro compound and a reducing agent, for example hydrazine hydrate or sulfur. Instead of the tribrom-ms-naphto-dianthrone, one can also use trichlor-ms-naphtodianthrone.
