  Verfahren zur Herstellung     eines        stickstoffhaltigen    Kondensationsproduktes  des     Fluoranthens.       Es wurde gefunden, dass ein stickstoff  haltiges Kondensationsprodukt des     Fluor-          anthens        hergestellt    werden kann, wenn man       Di-        (V-anthrachinonyl)-diaminofluo@ranthen,          i    das die beiden sekundären     Aminogruppen    an  denselben Stellen des     Fluoranthenkernes    ge  bunden enthält, die die Bromatome im     Di-          bromfluoranthen    einnehmen,

   das durch     Bro-          mierung    von     Fluoranthen    erhalten wird, mit  kondensierenden Mitteln behandelt.  



  Das neue Kondensationsprodukt ist ein  rotbraunes Pulver, das Baumwolle     aus    rot  violetter     güpe    in reinen     rotstichigbraiuien     Tönen färbt.  



  Das dem Verfahren als Ausgangsprodukt  dienende     Di    -     W-        anthrachinonyl)    -     diamino-          fluoranthen    kann durch Umsetzen von 1     Mol          Dibromfluoranthen    mit 2     Mol        1-Amino-          anthrachinon,    beispielsweise wie folgt erhal  ten werden.  



  7,2 Teile     Dibromfluoranthen,    hergestellt  durch     Bromieren    von     Fluoranthen    in Schwe-         felkohlenstoff    nach Annalen der Chemie,  488, Seite 115, 9 Teile     1-Aminoanthrachinon,     7     Teile    entwässertes     Natriumacetat    und  1,6 Teile     Kupferchlorür    werden in 145 Tei  len Nitrobenzol verteilt     und    während 16 Stun  den bei einer Temperatur von     190-200'    ge  rührt.

   Das Reaktionsgemisch wird heiss fil  triert, der Rückstand mit Nitrobenzol sowie  Benzol und Alkohol ausgewaschen und zur  Reinigung zuerst mit verdünnter Salzsäure,  dann mit Alkohol     ausgekocht.    Man erhält in  guter     Ausbeute    ein braunes, kristallines Pul  ver, das     konz.    Schwefelsäure gelboliv färbt  und bis 400' nicht schmilzt.  



  Als kondensierende Mittel, die sauren  oder alkalischen Charakter     besitzen    und die  für sich allein,     gegebenenfalls    miteinander  kombiniert oder zusammen mit     indifferenten          Lösungs-        bezw.    Verdünnungsmitteln verwen  det werden können, kommen in Betracht:  Aluminiumchlorid,     Natriumamid,        Acetyl-          chlorid,        Benzoylchlorid,        Chlorsulfonsäure    und      hochprozentige Schwefelsäure.

   Die Einwir  kung der kondensierenden Mittel kann bei  tiefer, mittlerer oder     gegebenenfalls        stark    er  höhter Temperatur vorgenommen werden.  



       Beispiel:     24 Teile wasserfreies     Alurniniumehlorid     werden mit 6 Teilen Kochsalz vermischt und  unter Rühren     bei    120   verschmolzen. Nun  gibt man 1 Teil     Di-(1'-anthrachinonyl)-di-          aminofluorantlien    zu und rührt während  2 Stunden bei 120-125  . Schliesslich trägt  man die Schmelze in Eis aus, kocht mit ver  dünnter Salzsäure auf und filtriert den er  haltenen Farbstoff ab.



  Process for the preparation of a nitrogen-containing condensation product of fluoranthene. It has been found that a nitrogen-containing condensation product of fluoranthene can be produced if one contains di- (V-anthraquinonyl) -diaminofluoranthene, which contains the two secondary amino groups bound to the same positions in the fluoranthene nucleus that the bromine atoms in Taking dibromofluoranthene,

   which is obtained by bromination of fluoranthene treated with condensing agents.



  The new condensation product is a red-brown powder that dyes cotton from red-violet güpe in pure reddish-brown tones.



  The di-W-anthraquinonyl) -diaminofluoranthene used as the starting product for the process can be obtained, for example, as follows by reacting 1 mol of dibromofluoranthene with 2 mol of 1-aminoanthraquinone.



  7.2 parts of dibromofluoranthene, prepared by brominating fluoranthene in carbon sulphide according to Annalen der Chemie, 488, page 115, 9 parts of 1-aminoanthraquinone, 7 parts of dehydrated sodium acetate and 1.6 parts of copper chloride are distributed in 145 parts of nitrobenzene and during Stirred for 16 hours at a temperature of 190-200 '.

   The reaction mixture is filtered hot, the residue is washed out with nitrobenzene and benzene and alcohol and boiled first with dilute hydrochloric acid and then with alcohol for cleaning. A brown, crystalline powder is obtained in good yield, the conc. Sulfuric acid turns olive yellow and does not melt until 400 '.



  As condensing agents which have acidic or alkaline character and which stand alone, optionally combined with one another or together with indifferent solutions or. Thinners that can be used are: aluminum chloride, sodium amide, acetyl chloride, benzoyl chloride, chlorosulfonic acid and high-percentage sulfuric acid.

   The action of the condensing agent can be carried out at a low, medium or, if appropriate, greatly increased temperature.



       Example: 24 parts of anhydrous aluminum chloride are mixed with 6 parts of table salt and melted at 120 ° while stirring. 1 part of di- (1'-anthraquinonyl) -diaminofluorantlien is now added and the mixture is stirred at 120-125 for 2 hours. Finally, the melt is poured out in ice, boiled with dilute hydrochloric acid and the dye obtained is filtered off.
