  <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 das     Kondensa-          tionsprodukt    aus, 1     Mol        2,8-Dibromchrysen     und 2     Mol        5-Amine-1,9-anthrapyrimidin    kon  densierende     Mittel    einwirken lässt.  



  Das     stickstoffhaltige        Kondensationspro-          dukt    bildet ein dunkles Pulver, das sich in       konzentrierter        Schwefelsäure    mit schmutzig  violetter Farbe, löst und Baumwolle aus brau  ner     Küpe    in echten,     braunen,    Tönen färbt.  



  Die Einwirkung kondensierender Mittel,  die oxydierend wirken können, wie z. B.       A.luminiumcblarid,    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       Ka.rbazolringe    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,     Alkalihyp@ochloritlösung     oder     Perboratlösung,    gereinigt werden.

      <I>Beispiel:</I>    1     Teil    des     Kondensationsproduktes    aus  1     Mol        2,8-Dibromchrysen    und 2     Mol        5-Amino-          1,9-anthrapyrimidin    werden bei 0-5   in  18 Teile     Sähwef        elsäure    96%ig eingetragen  und 16 Stunden bei     0=5      gerührt. Nun trägt  man in     FEils,    .gibt etwa 0,4 Teile Natrium  nitrit zu und     rührt    5 Stunden kräftig.

   Die  Reaktion ist nun beendet und der in sehr  guter     Ausbeute        erhaltene    Farbstoff kann ab  filtriert,     gewaschen    und getrocknet werden.



  <B> Additional patent </B> 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 if the condensation product of 1 mol of 2,8-dibromochrysenic and 2 mol of 5-amine-1,9-anthrapyrimidine condensing agents is allowed to act.



  The nitrogen-containing condensation product forms a dark powder which dissolves in concentrated sulfuric acid with a dirty purple color and dyes cotton from a brown vat in real, brown tones.



  The action of condensing agents that can have an oxidizing effect, such as. B. A.luminiumcblarid, 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. Ka.rbazole rings are very likely to be formed on exposure to condensing agents.

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

      <I> Example: </I> 1 part of the condensation product from 1 mol of 2,8-dibromochrysenic and 2 mol of 5-amino-1,9-anthrapyrimidine are added to 18 parts of 96% sulfuric acid at 0-5 and for 16 hours stirred at 0 = 5. Now you carry in parts, add about 0.4 parts of sodium nitrite and stir vigorously for 5 hours.

   The reaction has now ended and the dye obtained in very good yield can be filtered off, washed and dried.
