Description

  

  Verfahren zur Darstellung eines Derivates des     Dibenzpyrencliinons.       Im Hauptpatent ist ein Verfahren zur  Darstellung eines Derivates des     Dibenzpyren-          chinons    beschrieben, bei dem     Monoamino-          dibenzpyrenchinori    mit     Benzoylchlorid    behan  delt wird.  



  Es wurde nun gefunden; dass man eben  falls ein Derivat des     Dibenzpyrenchinons    von  ähnlichen wertvollen Eigenschaften erhalten  kann, wenn man     Monoaminodibenzpyren-          chinon,    erhältlich durch Nitrieren von     Dibenz-          pyrenchinon    von der Formel  
EMI0001.0012     
    in Nitrobenzol mit 96     %iger    Salpetersäure  bei     80-100"    und Reduktion des erhaltenen    Nitrokörpers mit     Schwefelnatriumlösung    bei  <B>90-1000</B> C, mit     1-Aminoanthracbinon-2-car-          bonsäurechlorid    behandelt.  



  Der neue Körper kristallisiert in feinen  Nadeln, löst sich in konzentrierter Schwefel  säure mit violetter Farbe und färbt Baum  wolle aus blauroter     Küpe    in orangefarbenen  Tönen von sehr guter Echtheit.  



  <I>Beispiel:</I>  Man suspendiert 35 Teile     Monoamino-          dipenzpyrenchinori,    dargestellt z. B. durch  Reduktion des     Mononiti-odibenzpyi-enchinons,     welches durch Nitrieren von     Dibenzpyren-          chinon        in        Nitrobenzol        mit        96        %        iger        Salpeter-          säure    erhalten wird, mit Schwefelnatrium,  in 1250 Teilen Nitrobenzol,

   gibt 30 Teile  1 -     Aminoanthrachinon    - 2 -     carbonsäurechlorid     hinzu und erwärmt eine kurze Zeit lang auf  190-205 0 C. Darauf lässt man erkalten,  saugt ab und arbeitet in der üblichen Weise  auf.



  Process for the preparation of a derivative of Dibenzpyrencliinons. The main patent describes a process for the preparation of a derivative of dibenzpyrenquinone, in which monoamino dibenzpyrenchinori is treated with benzoyl chloride.



  It has now been found; that one can also obtain a derivative of dibenzpyrenquinone of similar valuable properties by using monoaminodibenzpyrenquinone, obtainable by nitrating dibenzpyrenquinone of the formula
EMI0001.0012
    in nitrobenzene with 96% nitric acid at 80-100 "and reduction of the resulting nitro body with sodium sulphide solution at <B> 90-1000 </B> C, treated with 1-aminoanthracbinone-2-carboxylic acid chloride.



  The new body crystallizes in fine needles, dissolves in concentrated sulfuric acid with a violet color and dyes cotton from the blue-red vat in orange shades of very good fastness.



  <I> Example: </I> 35 parts of monoamino-dipenzyrenchinori, shown e.g. B. by reducing the Mononiti-odibenzpyi-enchinons, which is obtained by nitrating dibenzpyrenquinone in nitrobenzene with 96% nitric acid, with sodium sulphide, in 1250 parts of nitrobenzene,

   30 parts of 1-aminoanthraquinone-2-carboxylic acid chloride are added and the mixture is heated to 190-205 ° C. for a short time. It is then allowed to cool, suctioned off and worked up in the usual way.
