Description

  

      Verfahren    zur Herstellung eines     stickstoffhaltigen    Kondensationsproduktes.    Es     wurde    gefunden,     d:ass    ein     süekstoff-          haltiges    Kondensationsprodukt hergestellt  werden kann,     wenn    man auf     D'i-(5'-cinn-          amoylamino-1'-anthrachinonyl-)        2,8-diamino-          chrysen    kondensierende Mittel einwirken     lässt.     



       Das,        stickstoffhaltige        Kondensationspro-          dukt    färbt aus     gel:b-roter        Küpe        Baumwolle    in  reinen     -elbbraunen    Tönen von hervorragen  den     Echtheiten.     



  Die Einwirkung     kondensierender        Mittel,     die oxydierend wirken können, wie z. B.  Aluminiumchlorid, gegebenenfalls in Gegen  wart organischer Säurechloride und von  Z     erdünnungs-    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          Karba.zolringe    .gebildet.  



  Das neue stickstoffhaltige Kondensations  produkt kann durch ein- oder     mehrmaliges       Kristallisieren aus     arganischien    Lösungs  mitteln oder durch Behandlung     mit    oxydie  renden Mitteln, wie z. B.     Alkalinitritlösung     in saurem Medium,     Alkalihyp@ochloritlösung     oder     Perboratlösung,    gereinigt werden.

      <I>Beispiel:</I>    2 Teile     Di-(5'-cinnamoylamino-t'=anthra-          chinonyl-)2,8@diaminoehrysen        werden    bei 0  bis 5       in.    8,6 Teile 96%ige Schwefelsäure  eingetragen und 20 Stunden bei dieser Tem  peratur     weiter    gerührt. Zur Beendigung der       Farbstoffbildung    wird in Eis, -dem 0,6 Teile       1\Tatriumnitrit    zugefügt wurden, eingetragen,  5 Stunden kräftig gerührt und hierauf ab  filtriert, ausgewaschen und der Farbstoff mit       Wasser        angeteigt.  



      Process for the production of a nitrogen-containing condensation product. It has been found that a condensation product containing sweeteners can be produced if agents which condense D'i- (5'-cinnamoylamino-1'-anthraquinonyl) 2,8-diaminochrysenic are allowed to act.



       The nitrogen-containing condensation product dyes from yellow: b-red vat cotton in pure yellow-brown tones 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 higher or lower temperature. Particularly suitable as a condensing agent. are sulfuric acid and its derivatives, which are expediently applied at low temperatures. It is very likely that the action of condensing agents will form karba.zol rings.



  The new nitrogen-containing condensation product can medium by one or more times crystallization from arganic solvents or by treatment with oxydie-generating agents such. B. Alkali nitrite solution in acidic medium, alkali hyp @ chlorite solution or perborate solution.

      <I> Example: </I> 2 parts of di- (5'-cinnamoylamino-t '= anthraquinonyl-) 2,8 @ diaminoehrysen are added at 0 to 5 in. 8.6 parts of 96% sulfuric acid and 20 Stirred for hours at this temperature. To terminate the formation of the dye, ice to which 0.6 part of sodium nitrite has been added is introduced, stirred vigorously for 5 hours and then filtered off, washed out and the dye made into a paste with water.
