Description

       

  Verfahren zur Darstellung eines Derivates des     3.4.8.9-Dibenzpyren-6.10-chinons.       Im Hauptpatent ist ein Verfahren zur  Darstellung eines Derivates des     3.4.8.9-          Dibenzpyrenchinons    beschrieben, bei dem       3.4.8.9-Dibenzpyren-5.10-chinon    in saurem  Medium in Gegenwart von Katalysatoren mit  mindestens 1     Mol    eines chlorierend wirken  den Mittels behandelt wird.  



  Es wurde nun gefunden, dass man ein Deri  vat des     3.4.8.9-Dibenzpyren-5    .     10-chinons     von ähnlichen Eigenschaften erhalten kann,  wenn man 3.4.     8.9-Dibenzpyren-5.10-chinon     in saurem     Mediumin    Gegenwart von Kataly  satoren     finit    mindestens     l/2        Mol    eines     bromfie-          rend    und     mindestens        1/2        Mol    eines chlorierend  wirkenden Mittels behandelt.  



  Das erhaltene Reaktionsprodukt ist der  Analyse nach ein     Monobrommono-chlor-          3.    4. 8 .     9-dibenzpyi#en-5        .10-chinon,    das sich  in konzentrierter Schwefelsäure mit violetter  Farbe löst und aus blauroter     Küpe    gelb  orange Färbungen von sehr guter Echtheit  liefert.         Beispiel:       33,2 Teile     3.4.8.9-Dibenzpyreri-5.10-          chinon    werden in 300 Teilen     Chlorsulfon-          säure    gelöst.

   Man gibt ein Teil Jod hinzu,  leitet bei<B>600</B> C so lange Chlor ein, bis die  Gewichtszunahme einem     1/2        Mol    Chlor ent  spricht, fügt 9 Teile Brom bei<B>65-700</B>     (l/'     zu, rührt und arbeitet, sobald alles Brom  aufgenommen ist, in der üblichen Weise auf.



  Process for the preparation of a derivative of 3.4.8.9-dibenzpyrene-6.10-quinone. The main patent describes a process for the preparation of a derivative of 3.4.8.9-dibenzpyrenquinone, in which 3.4.8.9-dibenzpyren-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 3.4.8.9-dibenzpyrene-5. 10-quinones of similar properties can be obtained if one 3.4. 8.9-dibenzpyrene-5.10-quinone in an acid medium in the presence of catalysts finitely treated at least 1/2 mol of a brominating agent and at least 1/2 mol of a chlorinating agent.



  The reaction product obtained is, according to analysis, a monobromo mono-chloro-3. 4. 8. 9-dibenzpyi # en-5 .10-quinone, which dissolves in concentrated sulfuric acid with a violet color and, from a blue-red vat, gives yellow-orange colorations of very good fastness. Example: 33.2 parts of 3.4.8.9-dibenzpyreri-5.10-quinone are dissolved in 300 parts of chlorosulfonic acid.

   One part iodine is added, chlorine is introduced at <B> 600 </B> C until the increase in weight corresponds to 1/2 mole of chlorine, and 9 parts bromine are added at <B> 65-700 </B> (1 / 'close, stir and work up as usual as soon as all the bromine has been taken up.

PATENTANSPRUCH: Verfahren zur Darstellung eines Derivates des 3.4.8.9-Diberizpyren-5.10-chinons, da durch gekennzeichnet, dass man 3.4.8.9 Dibenzpyren-5.10-chinon in saurein Medium in Gegenwart von Katalysatoren mit min desten 1/2 Mol eines bromfierend wirkenden und mindestens 1/2 Mol eines chlorierend wirkenden Mittels behandelt. Das erhaltene Reaktionsprodukt ist der Analyse nach ein Monobrommono-chlor- 3.4.8.9-diberrzpyren-5.10-chinon, das sich in kotzentrierter Schwefelsäure mit violetter Farbe löst und aus blauroter güpe gelb- orange Färbungen von sehr guter Echtheit liefert. PATENT CLAIM: Process for the preparation of a derivative of 3.4.8.9-diberizpyrene-5.10-quinone, characterized in that 3.4.8.9 dibenzpyrene-5.10-quinone in an acidic medium in the presence of catalysts with at least 1/2 mol of a brominating effect and treated at least 1/2 mole of a chlorinating agent. Analysis of the reaction product obtained is a monobromo-mono-chloro-3.4.8.9-diberrzpyren-5.10-quinone, which dissolves in fecal sulfuric acid with a violet color and gives yellow-orange colorations of very good fastness from a blue-red güpe.
