      Zusatzpatent    zum Hauptpatent Nr. 171369.    Verfahren zur Herstellung eines stickstoffhaltigen Kondensationsproduktes.    Es wurde     gefunden,    dass ein stickstoff  haltiges     Kondensationsprodukt    erhalten wer  den kann, wenn 1     Mol        bromiertes        1.2-Phtlial-          oyl-6-monochlorcarbazol,    das durch     Bromieren     von     1.2-Phthaloyl-6-moriochloi-carbazol    erhält  lich ist und etwa 3 Atome Brom enthält,

   mit  1     Alol        1.4-Monoberizoyldiaminoarithrachinon     zur     Unisetzung    gebracht und das gebildete  Produkt mit sauren kondensierenden     Mitteln     behandelt wird.  



  Das stickstoffhaltige Kondensationsprodukt  stellt ein dunkles Pulver dar, das sich in  konzentrierter Schwefelsäure mit schwarz  brariner Farbe löst und Baumwolle aus der       Küpe    in echten     Korinth-Tönen    färbt.  



  <I>Beispiel:</I>  25,0 Teile     bromiertes        l.2-Phthaloyl-6-          chlorcarbazol,    erhältlich durch     Bromieren    des       1.2-Phthaloyl-6-chlorcar-bazols    in Gegenwart  von Jod in Nitrobenzol bei     150-1600,    und  das etwa 3 Atome Brom enthält, 17,1 Teile  1 . 4 -     Monoberizoyldiarninoanthrachinon,    10  Teile Soda, 2 Teile Kupferacetat und 200    Teile Naphthalin werden zusammengeschmol  zen und während 18     Stunden    zum Sieden er  hitzt.

   Man lässt dann etwas abkühlen und  verdünnt bei etwa 120   mit 200 Teilen Chlor  benzol, filtriert noch heiss ab, wäscht nach  einander mit Chlorbenzol und Alkohol und  kocht dann zur     Entfernung    von anorganischen  Bestandteilen mit Wasser unter Zusatz von  etwas konzentrierter Salzsäure aus.  



  30 Teile wasserfreies, gemahlenes Alu  miniumchlorid werden vorsichtig in 60 Teile       Pyridin    eingetragen. Bei etwa 100   gibt man  in diese Schmelze 10 Teile des im erster)     Ab-          satze    erhaltenen Produktes zu und hält die  Schmelze 1 Stunde bei     140-150'.    Der neue  Farbstoff kann durch Eintragen der Schmelze  in wässerige alkalische     Hydrosulfitlösung,    Ab  filtrieren von     unverküpbaren    Verunreinigun  gen und Oxydation mit Luft rein erhalten  werden.



      Additional patent to main patent No. 171369. Process for the production of a nitrogen-containing condensation product. It has been found that a nitrogen-containing condensation product can be obtained if 1 mole of brominated 1,2-phtlialoyl-6-monochlorocarbazole, which is obtained by brominating 1.2-phthaloyl-6-moriochloi-carbazole and contains about 3 atoms of bromine ,

   with 1 Alol 1,4-Monoberizoyldiaminoarithraquinone brought to Unisetzung and the product formed is treated with acidic condensing agents.



  The nitrogen-containing condensation product is a dark powder that dissolves in concentrated sulfuric acid with a black brary color and dyes cotton from the vat in real Corinthian tones.



  <I> Example: </I> 25.0 parts of brominated 1,2-phthaloyl-6-chlorocarbazole, obtainable by brominating the 1,2-phthaloyl-6-chlorocarbazole in the presence of iodine in nitrobenzene at 150-1600, and that contains about 3 atoms of bromine, 17.1 parts 1. 4 - Monoberizoyldiarninoanthraquinone, 10 parts of soda, 2 parts of copper acetate and 200 parts of naphthalene are melted together and heated to the boil for 18 hours.

   It is then allowed to cool slightly and diluted at about 120 with 200 parts of chlorobenzene, filtered while still hot, washed successively with chlorobenzene and alcohol and then boiled with water with the addition of a little concentrated hydrochloric acid to remove inorganic components.



  30 parts of anhydrous, ground aluminum chloride are carefully added to 60 parts of pyridine. At about 100, 10 parts of the product obtained in the first paragraph are added to this melt and the melt is kept at 140-150 'for 1 hour. The new dye can be obtained in pure form by introducing the melt into aqueous alkaline hydrosulfite solution, filtering off uncoupling impurities and oxidizing with air.
