Description

  

      Zusatzpatent    zum     Hauptpatent    Nr. 218368.    Verfahren zur Herstellung eines stickstoffhaltigen Kondensationsproduktes.    Es wurde gefunden, dass ein stickstoff  haltiges Kondensationsprodukt hergestellt wer  den kann, wenn man auf     Di-(4'-benzoylamino-          1'-anthrachinonyl-)2,8-diaminochrysen    konden  sierende Mittel einwirken lässt.  



  Das     stickstoffhaltigeKondensationsprodukt     bildet ein braunschwarzes Pulver, das Baum  wolle aus     rotoranger        Küpe    in     rötlichbrannen     Tönen färbt.     Sodakoch-,    Chlor- und Lichtecht  heit sind ausgezeichnet.  



  Die Einwirkung kondensierender Mittel,  die oxydierend wirken können, wie z. B.  Aluminiumchlorid, gegebenenfalls in Gegen  wart organischer Säurechloride und von     Ver-          dünnungs-    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 Kri  stallisieren aus organischen Lösungsmitteln  oder durch Behandlung mit oxydierenden  Mitteln, wie z.

   B.     Alkalinitritlösung    in     saurem     Medium,     Alkalihypochloritlösung    oder     Perbo-          ratlösung,    gereinigt werden.  



       Beispiel:     3 Teile     Di-(4'-benzoylamino-1'-anthrachi-          nonyl-)2,8-diaminochrysen    werden in 30 Teile  90     o/oige    Schwefelsäure eingetragen und 18  Stunden bei 16-22 o gerührt. Zur Beendigung  der     Farbstoffbildung    wird in Eis, das mit  .etwas     Natriumnitrit    versetzt ist, eingetragen,  4 Stunden kräftig gerührt und hierauf filtriert,  ausgewaschen     und    getrocknet.



      Additional patent to main patent No. 218368. Process for the production of a nitrogen-containing condensation product. It has been found that a nitrogen-containing condensation product can be produced when condensing agents are allowed to act on di- (4'-benzoylamino-1'-anthraquinonyl) 2,8-diaminochrysenic.



  The nitrogen-containing condensation product forms a brown-black powder, which colors the cotton from the red-orange vat in reddish tones. Soda, chlorine and lightfastness are excellent.



  The action of condensing agents that can have an oxidizing effect, such as. B. aluminum chloride, possibly in the presence of organic acid chlorides and diluents or solvents, can take place at higher or lower temperatures. Sulfuric acid and its derivatives, which are expediently applied at low temperature, are particularly suitable as condensing agents. Carbazole rings are very likely to be formed upon exposure to condensing agents. The new nitrogen-containing condensation product can stall by one or more times Kri from organic solvents or by treatment with oxidizing agents, such as.

   B. Alkali nitrite solution in acidic medium, alkali hypochlorite solution or perborate solution, can be cleaned.



       Example: 3 parts of di- (4'-benzoylamino-1'-anthraquinoneyl) 2,8-diaminochrysene are introduced into 30 parts of 90% sulfuric acid and the mixture is stirred at 16-22 ° for 18 hours. To terminate the formation of the dye, it is poured into ice to which a little sodium nitrite has been added, stirred vigorously for 4 hours and then filtered, washed and dried.
