  Verfahren zur Darstellung von     Bibenzoyldiamino-3.    4. B .     9-dibenzpyrenehinon-6    .10.    In dem Schweiz. Patent Nr. 144577 und  Zusätzen wird die Darstellung wertvoller ein  heitlicher     Substitutionsprodukte    des 3.4.     8:9-          dibenzpyrenchinon-5.10    aus dessen Mono  aminoderivat beschrieben.  



  Es wurde nun gefunden, dass man eben  falls ein als     Farbstoff    und Zwischenprodukt  wertvolles     Substitutionsprodukt    des     Dibenz-          pyrenchinons    erhalten kann, wenn man 1     Mol          Diamino    -3.4.8.9 -     dibenzpyrenchinon    -<B>5.</B> 10  der Formel  
EMI0001.0013     
    mit mindestens 2     Mol        Benzoylchlorid    behan  delt.  



  <I>Beispiel:</I>  10 Gewichtsteile     Diamino-3    . 4 . 8 .     9-dibenz-          pyrenchinon.-5.10    der angegebenen Formel  werden in 150 Gewichtsteilen Nitrobenzol zum  Sieden erhitzt, und in die kochende Suspen  sion lässt man allmählich 10 Gewichtsteile       Benzoylchlorid        eintropfen.    Vorübergehend tritt  Lösung ein, dann scheidet sich noch in der     Sie-          debitze    das braunrote     Dibenzoylderivat    aus. Es  wird noch warm abgesaugt und mit Sprit  gewaschen.

   Der so dargestellte Farbstoff lie  fert aus roter     güpe    kräftig     gelbstichig    rote  Färbungen von guten Echtheitseigenschaften.



  Process for the preparation of bibenzoyldiamino-3. 4. B. 9-dibenzpyrenehinone-6 .10. In Switzerland. Patent No. 144577 and additions will be the representation of valuable uniform substitution products of 3.4. 8: 9-dibenzpyrenquinone-5.10 described from its mono amino derivative.



  It has now been found that a substitution product of dibenzpyrenquinone which is valuable as a dye and intermediate can also be obtained if 1 mol of diamino -3.4.8.9 - dibenzpyrenquinone - <B> 5. </B> 10 of the formula
EMI0001.0013
    treated with at least 2 moles of benzoyl chloride.



  <I> Example: </I> 10 parts by weight of Diamino-3. 4th 8th . 9-dibenzpyrenchinon.-5.10 of the formula given are heated to boiling in 150 parts by weight of nitrobenzene, and 10 parts by weight of benzoyl chloride are gradually added dropwise to the boiling suspension. Solution occurs temporarily, then the brown-red dibenzoyl derivative is still precipitated in the boiling point. It is sucked off while still warm and washed with fuel.

   The dyestuff thus represented delivers strong yellow-tinged red dyeings with good fastness properties from a red güpe.
