Description

  

  Verfahren zur Darstellung eines Derivates des     3.4.8.9-Dibenzpyren-6.10-ehinons.       Im Hauptpatent ist ein Verfahren zur Dar  stellung eines Derivates des     3.4.8.9-Di-          benzpyren-5.        10-chinons    beschrieben, bei dem  3. 4. 8 .     9-Dibenzpyren-5.10-chinon    in saurem  Medium in Gegenwart von Katalysatoren  mit mindestens 1     Mol    eines chlorierend wir  kenden Mittels behandelt wird.  



  Es wurde nun gefunden, dass man ein  Derivat des 3 . 4. 8 .     9-Diberizpyren-5    .     10-chi-          nons    von ähnlichen Eigenschaften erhalten  kann, wenn man     3.4.8.9-Dibenzpyren-          5.10-chinon    in saurem Medium in Gegen  wart von Katalysatoren mit mindestens 2     Mol     eines chlorierend wirkenden Mittels behandelt.

      Das erhaltene Reaktionsprodukt ist der  Analyse nach ein     Tetrachlor-3.4:8.9-Di-          benzpyren-5.10-chinon,    das sich in konzen  trierter Schwefelsäure mit     rotstichigblauer     Farbe löst und aus     rotstichig    violetter     Küpe          grünstichiggelbe    Färbungen von- sehr guter  Echtheit liefert.

      <I>Beispiel:</I>    33,3 Teile reines 3. 4. 8 .     9-Dibenzpyi-en-          5    .     10-chinon,    wie es durch Sublimation, Kri  stallisation oder durch Auskochen von     Roh-          dibenzpyrenchinonmit    hochsiedenden Lösungs  mitteln erhalten werden kann, werden unter  Rühren in 330 Teilen     Chlorsulfonsäure    gelöst.  Nach Zugabe von 3 Teilen Jod erhöht man  die Temperatur auf 60-65   C und leitet so  lange einen trockenen Chlorstrom ein, bis  eine Probe des Reaktionsproduktes sich in  konzentrierter Schwefelsäure mit     rotstichig     blauer Farbe löst. Man lässt erkalten und  arbeitet in der üblichen Weise auf.



  Process for the preparation of a derivative of 3.4.8.9-dibenzpyrene-6.10-ehinon. The main patent is a process for the presentation of a derivative of 3.4.8.9-dibenzpyrene-5. 10-quinones described, in the 3rd 4th 8th 9-dibenzpyrene-5.10-quinone is treated in an acidic medium in the presence of catalysts with at least 1 mol of a chlorinating agent.



  It has now been found that a derivative of the 3rd 4. 8. 9-diberizpyrene-5. 10-quinons of similar properties can be obtained if 3.4.8.9-dibenzpyrene-5.10-quinone is treated in an acidic medium in the presence of catalysts with at least 2 moles of a chlorinating agent.

      The reaction product obtained is, according to the analysis, a tetrachloro-3.4: 8.9-dibenzpyrene-5.10-quinone, which dissolves in concentrated sulfuric acid with a reddish-blue color and gives greenish-yellow colorations of very good fastness from a reddish-purple vat.

      <I> Example: </I> 33.3 parts of pure 3. 4. 8. 9-Dibenzpyi-en- 5. 10-quinone, as it can be obtained by sublimation, crystallization or by boiling raw dibenzpyrenchinonmit high-boiling solvents, are dissolved in 330 parts of chlorosulfonic acid with stirring. After adding 3 parts of iodine, the temperature is increased to 60-65 ° C. and a stream of dry chlorine is passed in until a sample of the reaction product dissolves in concentrated sulfuric acid with a reddish blue color. You let it cool down and work up in the usual way.
