Description

  

  Verfahren zur Darstellung eines wertvollen     Küpenfarbstoffes.       Im Hauptpatent ist ein Verfahren zur Dar  stellung eines wertvollen     Kiipenfarbstoffes    be  schrieben, bei dem     Aminodibenzanthron,    das  erhalten werden kann durch Reduktion des  durch Nitrieren von     Dibenzanthron    entstehen  den     Mononitrodibenzanthrons,    mit einem in       1-Stellung    negativ substituierten     Anthrachinon     kondensiert wird.  



  Es wurde nun gefunden, dass man einen  ähnlichen wertvollen     Küpenfarbstoff    erhält,  wenn man 2     Mol.        Aminodibenzanthron,    das er  halten werden kann durch Reduktion des  durch Nitrieren von     Dibenzanthron    entstehen  den     Mononitrodibenzanthrons,    mit einem     Mol.     eines zweifach substituierten     Dibenzanthrons,     das durch     Halogenieren    von     Dibenzanthron     in Gegenwart eines organischen Lösungsmittels  erhalten werden kann, kondensiert.

   Durch die       Halogenierung    von     Dibeuzanthron    in organi  schen Lösungsmitteln, zum Beispiel in     Nitro-          oder        Trichlorbenzol,    erhält man ein zweifach       halogensubstituiertes    Produkt, bei dem die    Halogenatome sich stets an der gleichen Stelle  des Moleküls befinden.  



  Die Kondensation führt man zweckmässig  in hochsiedenden     Lösungs-    oder Verdünnungs  mitteln aus, und man kann hierbei auch säure  bindende Mittel zusetzen. Vielfach ist die  Anwendung von Katalysatoren vorteilhaft, als  welche beispielsweise Gemische von Natrium  acetat 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 blauschwarzen; her  vorragend echten Tönen.  



       Beispiel     Eine Suspension von 62 Teilen     Dibrom-          dibenzanthron    in 1000- Teilen     Nitrobenzol    wird  mit 94 Teilen     Aminodibenzanthron,    50 Teilen       Natriumacetat    und 10 Teilen     Kupferoxyd    so  lange unter Rühren gekocht, bis die     Farb-          stoffbildung    beendet ist. Dann wird wie üblich  aufgearbeitet.      Man kann das     Aminodibenzanthron    wäh  rend der Reaktion, aus der entsprechenden  Nitroverbindung und einem Reduktionsmittel  z. B.     Hydrazinhydrat    oder Schwefel erzeugen.

    Statt des     Dibromdibenzanthrons    kann man  auch die     äquivalante    Menge     Dichlordibenz-          anthron    verwenden.



  Process for the preparation of a valuable vat dye. The main patent describes a process for the preparation of a valuable Kiipen dye in which aminodibenzanthrone, which can be obtained by reducing the mononitrodibenzanthrone formed 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 it can be obtained by reducing the mononitrodibenzanthrone formed by nitrating dibenzanthrone, with one mole of a doubly substituted dibenzanthrone, which is obtained by halogenating dibenzanthrone can be obtained in the presence of an organic solvent, condensed.

   Halogenation of dibeuzanthrone in organic solvents, for example in nitrobenzene or trichlorobenzene, gives a doubly halogen-substituted product in which the halogen atoms are always in the same position on the molecule.



  The condensation is expediently carried out in high-boiling solvents or diluents, and acid-binding agents can also be added here. In many cases, the use of catalysts is advantageous, as which, 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 blue-black; excellent real tones.



       EXAMPLE A suspension of 62 parts of dibromodibenzanthrone in 1000 parts of nitrobenzene is boiled with 94 parts of aminodibenzanthrone, 50 parts of sodium acetate and 10 parts of copper oxide with stirring until the formation of color has ended. Then it is worked up as usual. You can the aminodibenzanthrone during the reaction, from the corresponding nitro compound and a reducing agent z. B. produce hydrazine hydrate or sulfur.

    Instead of the dibromodibenzanthrone one can also use the equivalent amount of dichlorodibenzanthrone.
