  <B>Zusatzpatent</B> zum Hauptpatent Nr. 218368.         "Verfahren    zur Herstellung eines     stickstoffhaltigen        Kondensationsproduktes.       Es wurde gefunden, dass     .ein.    stickstoff  haltiges     Kondensationsprodukt    hergestellt  werden kann,     wenn.    man auf     Di-(4'-benzoyl-          amino    -<B>l-</B>     'anthrachinonyl)    - 2,6 -     diaminonaph-          thalin    kondensierende Mittel einwirken lässt.  



  Das stickstoffhaltige Kondensationspro  dukt bildet ein dunkles Pulver, das sich in  konzentrierter     Schwefelsäure    mit grüner  Farbe löst und Baumwolle aus     blauroter          Küpe    in kräftigen sehr echten violetten  Tönen färbt.  



  Die     Einwirkung    kondensierender     Mittel,     die oxydierend wirken können, wie     z.    B.       Aluminiumohlorid,    ,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       Kristallisieren    aus organischen Lösungs  mitteln oder     durch    Behandlung mit oxydie  renden     Mitteln,    wie z. B.     Alkalinitritlösung     in saurem     Medium,        Alkalihypochloritlösung     oder     Perboratlösung,    gereinigt werden. Hier  bei wird die schon an der Luft erfolgende  Oxydation allfällig entstandener wasserstoff  reicherer     Zwischenprodukte    zu Ende geführt.

      <I>Beispiel:</I>  3 Teile     Di-(4'-benzoylamino-1'-anthra-          .chinonyl)-2,6-diaminonaphthalin    (siehe Pa  tentschrift     Nr.212331)    werden bei einer  Temperatur von 0-6   in 54     Teile    96     %iger          Schwefelsäure        eingetragen    und 18 Stunden  bei .dieser Temperatur     gerührt.    Zur Beendi  gung der     Farbstoffbildung    wird in Eis, dem  etwas     Natriumnitrit    zugefügt     worden    ist,  eingetragen,     11/2,    Stunden kräftig gerührt  und hierauf     filtriert,

      ausgewaschen und ge  trocknet.



  <B> Additional patent </B> to main patent no. 218368. "Process for the preparation of a nitrogen-containing condensation product. It has been found that .a. Nitrogen-containing condensation product can be prepared if .di- (4'-benzoylamino - <B> l- </B> 'anthraquinonyl) - 2,6 - diaminonaphthalene condensing agents can act.



  The nitrogen-containing condensation product forms a dark powder that dissolves in concentrated sulfuric acid with a green color and dyes cotton from a blue-red vat in strong, very genuine purple tones.



  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 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 medium by one or more crystallization from organic solvents or by treatment with oxydie-generating agents, such as. B. Alkali nitrite solution in an acidic medium, alkali hypochlorite solution or perborate solution. Here at the oxidation already taking place in the air of any hydrogen-rich intermediate products that have arisen is brought to an end.

      <I> Example: </I> 3 parts of di- (4'-benzoylamino-1'-anthra-quinonyl) -2,6-diaminonaphthalene (see patent specification No. 212331) are at a temperature of 0-6 in Entered 54 parts of 96% sulfuric acid and stirred at this temperature for 18 hours. To complete the formation of the dye, it is added to ice to which a little sodium nitrite has been added, stirred vigorously for 11/2 hours and then filtered,

      washed out and dried.
