  Verfahren zur Darstellung eines wertvollen     Küpenfarbstoiees.            Ini    Hauptpatent ist ein Verfahren zur       Darstellung    eines     wertvollen        Küpenfarbsto,f-          fes        beschrieben,    bei dem     Amin.odibenzanthron,     das erhalten werden kann durch     Reduktion          des    durch Nitrieren von     Dibenzanthron    ent  stehenden     #vlononitrodibenzanthrons,

      mit einem       in        1-Stelluiig        negativ          Anthra-          chinon        kondensiert        wird.     



  Es wurde nun     gefunden,    dass man  einen ähnlichen wertvollen     Küpenfa.rb-          stoff    erhält, wenn man ?     Mol.        Amino-          dibenzanthron,    das erhalten werden kann  durch Reduktion des durch Nitrieren von       )ibenzanthron    entstehenden     Mononitrodi-          benzanthrons,    mit 1     Mol.        Diha,logenperylen-          chinon,    das durch direkte     Halogenierung     von     Perylenchinon    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     Kataly    sa-    Loren vorteilhaft, als welche beispielsweise  Gemische von     Natriumacetat    und Kupfer  salzen benutzt werden können.  



  Der neue     Kiipenfarbstoff    ist. ein schwarzes       Pulver;    er     ist    in konzentrierter Schwefel  säure mit     violetter    Farbe löslich und färbt  Baumwolle aus blauer     Küpe    in     blaus:chwa.rzen,     hervorragend echten Tönen.    <I>Beispiel:</I>    44 Teile     Dibromperylenchinon    werden  in<B>1000</B> Teilen Nitrobenzol mit 94     Teilen          Aminodibenzanthron_,    40 Teilen Natrium  acetat und 7 Teilen Kupferoxyd bis zur Be  endigung der     Farbsto.ffbildung    unter Rühren  gekocht und dann! in der üblichen Weise auf  gearbeitet.  



  Man kann das     Aminodibenzanthran    wäh  rend der Reaktion, aus der entsprechenden.  Nitroverbindung und einem Reduktionsmittel,  zum Beispiel     Hydrazinhydra.t    oder Schwefel,  erzeugen.



  Process for the representation of a valuable vat dye. The main patent describes a process for the preparation of a valuable vat dye, in the case of the amine.odibenzanthrone, which can be obtained by reducing the #vlononitrodibenzanthrone produced by nitrating dibenzanthrone,

      is condensed with an in 1-Stelluiig negative anthraquinone.



  It has now been found that one obtains a similar valuable vat fiber if one? Mol. Amino dibenzanthrone, which can be obtained by reducing the mononitrodibenzanthrone formed by nitrating) ibenzanthrone, with 1 mol. Diha, logenperylenquinone, which can be obtained by direct halogenation of perylene quinone. condensed.

   The condensation is expediently carried out in high-boiling solvents or diluents, and it can also be done here. add acid-binding agents. In many cases, the use of Kataly sa- Loren is advantageous, as which, for example, mixtures of sodium acetate and copper salts can be used.



  The new Kiipen dye is. a black powder; it is soluble in concentrated sulfuric acid with a violet color and dyes cotton from a blue vat blue: black, brilliantly real shades. <I> Example: </I> 44 parts of dibromoperylene quinone in <B> 1000 </B> parts of nitrobenzene with 94 parts of aminodibenzanthrone, 40 parts of sodium acetate and 7 parts of copper oxide are boiled with stirring until the dye has formed and then ! worked on in the usual way.



  You can get the aminodibenzanthrane during the reaction from the corresponding. Nitro compound and a reducing agent, for example hydrazine hydra.t or sulfur.
