Description

  

      Verfahren    zur Herstellung     eines        Küpenfarbstoffes.       Es wurde gefunden, dass ein wertvoller       Küpenfarbstoff        hergestellt    werden kann,  wenn man das     in    alkalischem Medium erhal  tene Kondensationsprodukt     aus        1-(Bzl-Benz-          anthronylamino)    - 5 -     aminoanthrachinon    mit  einem Mittel behandelt, das den Rest der  Formel  
EMI0001.0011     
    abgibt.

    Der neue Farbstoff ist ein olives Pulver,  das sich in Schwefelsäure grün löst und     aus     blauvioletter     Küpe    Baumwolle oder Zellwolle  in klaren oliven Tönen färbt.  



  Das dem vorliegenden Verfahren als     Aus-          O;angsprodukt    dienende alkalische Kondensa  tionsprodukt aus 1-     (Bzl    -     Benzanthronyl-          amino)-5-aminoanthrachinon    kann in bekann  ter Weise erhalten werden, z. B. unter Ver  wendung von alkoholischen     Atzalkalilösun-          gen        bezw.    Schmelzen (vergleiche     französische     Patentschriften Nr.<B>697231</B>     und    396583).  



  Als Mittel, die den Rest der obigen For  mel abgeben, kommen vorzugsweise reak  tionsfähige, funktionelle Derivate der     o-Chlor-          benzoesäure,    z. B. die     Säurehalogenide    und  insbesondere das Säurechlorid in Betracht.  



  Die Behandlung kann in an sich bekann  ter Weise z. B. durch Erhitzen in indifferen  ten, vorzugsweise hochsiedenden Lösungs  mitteln, wie     Nitrobenzol,    Naphthalin und     Di-          chlorbenzol    vorgenommen werden.

      <I>Beispiel:</I>  20 Teile alkalisches Kondensationspro  dukt     aus    1-     (Bzl    -     Benzanthronylamino)    - 5     -          a.minoanthrachinon    werden in 250 Teilen     Ni-          trobenzol    mit 20     Teilen        o-Chlorbenzoyl-          chlorid    2     Stunden    rückfliessend gekocht.  Nach Erkalten wird abgesaugt, der Rück  stand mit Nitrobenzol gewaschen und an  schliessend durch     Wasserdampfdestillation     der Farbstoff isoliert     und    getrocknet.



      Process for the production of a vat dye. It has been found that a valuable vat dye can be produced if the condensation product obtained in an alkaline medium from 1- (Bzl-benzanthronylamino) -5 - aminoanthraquinone is treated with an agent which corresponds to the remainder of the formula
EMI0001.0011
    gives.

    The new dye is an olive powder that dissolves green in sulfuric acid and dyes cotton or rayon from a blue-violet vat in clear olive tones.



  The alkaline condensation product of 1- (Bzl - benzanthronylamino) -5-aminoanthraquinone used as starting O; angsprodukt can be obtained in a known manner, e.g. B. using alcoholic caustic alkali solutions respectively. Melts (compare French Patent Nos. 697231 and 396583).



  As agents that release the remainder of the formula above, are preferably reactive, functional derivatives of o-chloro-benzoic acid, eg. B. the acid halides and especially the acid chloride into consideration.



  The treatment can in itself known ter way z. B. by heating in indifferen th, preferably high-boiling solvents such as nitrobenzene, naphthalene and dichlorobenzene can be made.

      <I> Example: </I> 20 parts of alkaline condensation product from 1- (Bzl - benzanthronylamino) - 5 - a.minoanthraquinone are refluxed in 250 parts of nitrobenzene with 20 parts of o-chlorobenzoyl chloride for 2 hours. After cooling, the product is filtered off with suction, the residue is washed with nitrobenzene and the dye is then isolated by steam distillation and dried.
