Description

  

  Verfahren     zur    Herstellung eines     stickstoffhaltigen    Kondensationsproduktes.         Es    wurde     ,gefunden,        @dass    ein stickstoff  haltiges     Kondensationsprodukt    hergestellt  werden kann, wenn man auf     Di-(5'-acetyl-          amino-1'-anthTar,hinony'1-)        2,8-diaminoch@rysen     kondensierende Mittel einwirken lässt.  



  Das     stickstoffhaltige    Kondensationspro  dukt bildet ein schwarzbraunes Pulver, das  sich in     konzentrierter    Schwefelsäure mit  grüner Farbe löst und Baumwolle aus     gelb-          stichigroter        Küpe    in     kräftig    braunen Tönen  von vorzüglichen     Echtheiten    färbt.  



  Die Einwirkung kondensierender     Mittel,     die oxydierend wirken können, wie z. B.  Aluminiumchlorid, gegebenenfalls in Gegen  wart organischer Säurechloride und von       Verdünnungs-    oder Lösungsmitteln, kann bei  höherer oder     niederer    Temperatur erfolgen.  Als     Kondensationsmittel    besonders geeignet  sind Schwefelsäure und ihre Derivate, die  zweckmässig bei     niederer    Temperatur ange  wandt     werden.    Sehr wahrscheinlich werden  bei der Einwirkung     kondensierender    Mittel       Karbazolringe    ,gebildet.

      Das. neue stickstoffhaltige Kondensations  produkt kann durch ein- oder mehrmaliges       Kristallisieren        aus    organischen Lösungs  mitteln oder durch Behandlung mit oxydie  renden Mitteln, wie z. B.     Alkalinitritlasung     in     saurem    Medium,     Alkalihypochloritlösung     oder     Perboratlösung,    gereinigt werden.    <I>Beispiel:</I>  2 Teile     Di-(5'-acetylamino-1'-anthrachi-          nonyl-)2,8-diaminoehrysen    werden bei 0 bis  6   in 36 Teile 96     ,"/oixe    Schwefelsäure einge  tragen und 18 Stunden bei 0 bis 6   gerührt.

    Nun trägt man in     Eis    ein gibt etwa 0,6 Teile       Natriumnitrit    zu und rührt 6 Stunden kräf  tig. Die     Reaktion    ist nun     beendet    und der  in sehr ,guter Ausbeute erhaltene Farbstoff  kann     abfiltriert,        gewaschen    und getrocknet  werden.



  Process for the production of a nitrogen-containing condensation product. It has been found that a nitrogen-containing condensation product can be produced if a condensing agent is allowed to act on di- (5'-acetyl-amino-1'-anthTar, hinony'1-) 2,8-diamino-rysene.



  The nitrogen-containing condensation product forms a black-brown powder, which dissolves in concentrated sulfuric acid with a green color and dyes cotton from a yellow-tinged red vat in strong brown shades with excellent fastness properties.



  The action of condensing agents that can have an oxidizing effect, such as. B. aluminum chloride, optionally in the presence of organic acid chlorides and diluents or solvents, can be carried out at a higher or lower temperature. Sulfuric acid and its derivatives, which are expediently applied at low temperature, are particularly suitable as condensing agents. It is very likely that carbazole rings will be formed upon exposure to condensing agents.

      The. new nitrogen-containing condensation product can medium by one or more crystallization from organic solvents or by treatment with oxydie-generating agents, such as. B. Alkalinitritelasung in acidic medium, alkali hypochlorite solution or perborate solution are cleaned. <I> Example: </I> 2 parts of di (5'-acetylamino-1'-anthraquinoneyl) 2,8-diaminoehrysene are added to 36 parts of 96% sulfuric acid at 0 to 6 and 18 Stirred at 0 to 6 hours.

    Now it is put into ice, about 0.6 parts of sodium nitrite are added and the mixture is stirred vigorously for 6 hours. The reaction has now ended and the dye obtained in very good yield can be filtered off, washed and dried.
