  Verfahren zur Herstellung eines     Nüpenfarbstoffes.       Es wurde     gefunden,    dass     ein    wertvoller       güpenfarbstoff    hergestellt werden kann,  wenn man 1     Mol    der nach dem Verfahren der       Schweiz.    Patentschrift Nr. 208531 erhält  lichen     Fluoranthendicarbonsäure    oder eines  ihrer     funktionellen    Derivate mit 2     Mol          4-Aminoanthrachinon-1(N),2-benzacridon    um  setzt.  



  Der Farbstoff stellt ein blaues Pulver  .dar, das sich in konzentrierter Schwefelsäure  mit     orangeroter    Farbe löst,     unterhalb    450       nicht    schmilzt und Baumwolle aus rotviolet  ter     güpe    in blaugrauen Tönen färbt.  



  Als funktionelle     Derivate    der     Fluor-          anthendiearbonsäure    werden zweckmässig ihre       Dihalogenide,    insbesondere das     Dichlorid,    das  durch Behandeln der freien     Dicarbonsäuren     mit z. B.     Thionylchlorid    erhältlich ist, ver  wendet.  



  Die Umsetzung erfolgt     vorteilhaft    durch  Erhitzen der Komponenten in     Lösungs-    oder       Verdünnungsmitteln,    wie z. B.     Di-    oder Tri-    Chlorbenzol, Nitrobenzol, Naphthalin oder  Chlornaphthalin.  



  <I>Beispiel:</I>  14,5 Teile     Fluoranthendicarbonsäure    wer  den durch Erhitzen auf 110-120' mit  20 Teilen     Thionylchlorid    in 750 Teilen  trockenem     o-Dichlorbenzol    in das     Säure-          dichlorid    verwandelt. Nach dem     Abdestillie-          ren,des        unverbrauchten        Thionylchlorids    lässt  man bei<B>150'</B>     eine,    heisse Lösung von 34 Tei  len     4-Aminoanthrachinon-1(N),2-benzacridon     in 350 Teilen     Dichlorbenzol    zufliessen.

   Nach  zweistündigem Rühren bei     150-160'    ist die       Farbstoffbildung    beendet. Man saugt in .der       Wärme    ab, wäscht mit     Dichlorbenzol    und  Alkohol aus und trocknet.



  Process for the production of a pebble dye. It has been found that a valuable high quality dye can be produced if 1 mole of the can be produced using the Swiss process. Patent No. 208531 obtained union fluoranthendicarboxylic acid or one of its functional derivatives with 2 moles of 4-aminoanthraquinone-1 (N), 2-benzacridone sets.



  The dye is a blue powder that dissolves in concentrated sulfuric acid with an orange-red color, does not melt below 450 and dyes cotton from red-violet ter güpe in blue-gray tones.



  Its dihalides, especially the dichloride obtained by treating the free dicarboxylic acids with z. B. thionyl chloride is available, ver used.



  The reaction is advantageously carried out by heating the components in solvents or diluents, such as. B. Di- or tri- chlorobenzene, nitrobenzene, naphthalene or chloronaphthalene.



  <I> Example: </I> 14.5 parts of fluoranthendicarboxylic acid are converted into the acid dichloride by heating to 110-120 'with 20 parts of thionyl chloride in 750 parts of dry o-dichlorobenzene. After the unused thionyl chloride has been distilled off, a hot solution of 34 parts of 4-aminoanthraquinone-1 (N), 2-benzacridone in 350 parts of dichlorobenzene is allowed to flow in at 150 parts.

   After two hours of stirring at 150-160 ', the dye formation is complete. It is suctioned off in the heat, washed with dichlorobenzene and alcohol and dried.
