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-(5'-benzoylamino-          8'        -metlioxy-   <B>l'-</B>     anthrachinonyl-)    2,8 -     diamino        -          ehrysen    kondensierende Mittel einwirken lässt.  



  Das stickstoffhaltige     Kondensationsprodukt     bildet ein rotbraunes bis schwarzes Pulver,  das sich in konzentrierter Schwefelsäure mit  grüner Farbe löst und Baumwolle aus gelb  roter     Küpe    in reinen, rotbraunen, sehr echten  Tönen färbt.  



  Die Einwirkung kondensierender Mittel,  die oxydierend wirken können, wie z. B. Alu  miniumchlorid, gegebenenfalls in Gegenwart  organischer Säurechloride und von     Verdün-          nungs-    oder Lösungsmitteln, kann bei höherer  oder niederer Temperatur erfolgen. Als Kon  densationsmittel besonders geeignet sind  Schwefelsäure und ihre Derivate, die zweck  mässig bei niederer Temperatur angewandt  werden. Sehr wahrscheinlich werden bei der  Einwirkung kondensierender Mittel     Karbazol-          ringe    gebildet.    Das neue     stickstoffhaltige    Kondensations  produkt kann durch ein- oder mehrmaliges  Kristallisieren aus organischen Lösungsmitteln  oder durch Behandlung mit oxydierenden  'Mitteln, wie z.

   B.     Alkalinitritlösung    in saurem  Medium,     Alkalihypochloritlösung    oder Per  boratlösung, gereinigt werden.    <I>Beispiel:</I>  1,2 Teile     Di-(5'-benzoylamino-8'-methoxy-          l'-anthrachinonyl)        2,8-diaminochrysen    werden       bei        0-51        in        36        Teile        96,2        %        ige        Schwefel-          säure    eingetragen und 21 Stunden bei dieser  Temperatur weiter gerührt.

   Zur Beendigung  der     Farbstoffbildung    wird in Eis, dem etwas       Natriumnitrit    zugefügt wurde, eingetragen,  1'/4 Stunde 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 prepared if one is to analyze on di- (5'-benzoylamino- 8 '-metlioxy- <B> l'- </B> anthraquinonyl-) 2,8-diamino-Ehrysen allows condensing agents to act.



  The nitrogen-containing condensation product forms a red-brown to black powder that dissolves in concentrated sulfuric acid with a green color and dyes cotton from a yellow-red vat in pure, red-brown, very real shades.



  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 take place at higher or lower temperatures. Sulfuric acid and its derivatives, which are expediently used at low temperatures, are particularly suitable as condensation agents. It is very likely that carbazole rings will be formed upon exposure to condensing agents. The new nitrogen-containing condensation product can be crystallized one or more times from organic solvents or by treatment with oxidizing agents, such as.

   B. Alkali nitrite solution in an acidic medium, alkali hypochlorite solution or Per borate solution are cleaned. <I> Example: </I> 1.2 parts of di- (5'-benzoylamino-8'-methoxy-l'-anthraquinonyl) 2,8-diaminochrysenic become 96.2% sulfur in 36 parts at 0-51 - Entered acid and stirred for a further 21 hours at this temperature.

   To terminate the formation of the dye, it is poured into ice to which a little sodium nitrite has been added, stirred vigorously for 1/4 hour and then filtered, washed and dried.
