Description

  

      Terfahren    zur Darstellung -von     Monobenzoylamino.4.5.8.9-dibenzpyrenehltion-3.10.       Gegenstand des vorliegenden Zusatz  patentes ist ein Verfahren zur Darstellung  von     Monobenzoylamino-4.   <B>5. 8.</B>     9-Dibenzpyren-          chinon-3.   <B>10,</B> dadurch gekennzeichnet,     dass    man       Konoamino-4.   <B>5.

   8.</B>     9-dibenzpyrenchinon-g.   <B>10,</B>  das durch     Nitrierung    von     4.5.8.9-dibenz-          pyrenchinoii-3.10    und Reduktion der     Mono-          nitroverbindung    erhältlich ist, mit     Benzoyl-          ohlorid    behandelt.  



  <I>Beispiel:</I>  <B>36</B> Gewichtsteile     Morioamino-4.5.8.9-          dibenzpyrenchinon-3.10    erhitzt man in<B>350</B>  Gewichtsteilen     Dimethylanilin    zum Sieden  und     lässt    langsam 20 Gewichtsteile     Benzoyl-          ohlorid        zutropfen.    Das     Monobenzoylamino-          4.   <B>5. 8.</B>     9-dibenzpyrenchinon-3.   <B>10</B> scheidet sich  in violetten     Nädelchen    ab. Die Lösungsfarbe  in konzentrierter Schwefelsäure ist gelbgrün.

    Aus der orangen     Küpe    liefert der Farbstoff  ein gedecktes Violett von guten Echtheits  eigenschaften.



      The method for the representation of monobenzoylamino.4.5.8.9-dibenzpyrenehltion-3.10. The subject of the present additional patent is a process for the preparation of monobenzoylamino-4. <B> 5. 8. 9-dibenzpyrene-quinone-3. <B> 10, </B> characterized in that one Konoamino-4. <B> 5.

   8. 9-dibenzpyrenquinone-g. <B> 10 </B> which is obtainable by nitration of 4.5.8.9-dibenzpyrenchinoii-3.10 and reduction of the mononitro compound, treated with benzoyl chloride.



  <I> Example: </I> <B> 36 </B> parts by weight of morioamino-4.5.8.9-dibenzpyrenquinone-3.10 are heated to boiling in <B> 350 </B> parts by weight of dimethylaniline and slowly allowed to leave 20 parts by weight of benzoyl chloride to drip. The monobenzoylamino 4. <B> 5. 8. 9-dibenzpyrenquinone-3. <B> 10 </B> is deposited in purple needles. The solution color in concentrated sulfuric acid is yellow-green.

    From the orange vat, the dye delivers a muted violet with good fastness properties.
