Description

  

  Verfahren zur Darstellung eines Derivates des     Dibenzpyrenehinons.       Es wurde gefunden, dass man ein wert  volles Derivat des     Dibenzpyrenchinons    erhal  ten kann, wenn man     Monooxydibenzpyren-          chinon,    wie es erhalten werden kann aus       Dibenzpyrenchinon    durch Nitrieren mit Sal  petersäure in einem organischen Lösungs  mittel,     Reduzieren,        Diazotieren    und Verkochen  der     Diazolösung,    mit einem     tnethylierenden     Mittel behandelt.  



  Der erhaltene Körper ist in Schwefelsäure  mit rotvioletter Farbe löslich und färbt aus  roter     Küpe    Baumwolle in lebhaften orangen  Tönen.  



  <I>Beispiel:</I>  7 Teile     i#lotiooxydibenzpyrenchinon,    her  gestellt wie oben angegeben, werden in der       30fachen    Menge Nitrobenzol mit 7 Teilen       p-Toluolstalfosäuremethylester    und 5 Teilen  Pottasche solange unter Rühren zum Sieden  erhitzt, bis die     Farbstoffbildung    beendet ist.    blau lässt erkalten, saugt ab und arbeitet in  der üblichen Weise auf.



  Process for the preparation of a derivative of dibenzpyrenehinone. It has been found that you can get a valuable derivative of dibenzpyrenquinone th if you monooxydibenzpyrenquinone, as it can be obtained from dibenzpyrenquinone by nitrating with nitric acid in an organic solvent, reducing, diazotizing and boiling the diazo solution with a Methylating agents treated.



  The body obtained is soluble in sulfuric acid with a red-violet color and dyes cotton in vivid orange tones from a red vat.



  <I> Example: </I> 7 parts of i # lotiooxydibenzpyrenquinone, produced as stated above, are heated to boiling with stirring in 30 times the amount of nitrobenzene with 7 parts of methyl p-toluene-stalphate and 5 parts of potash with stirring until the dye formation has ended. blue lets you cool down, sucks off and works up in the usual way.
