  <B>Zusatzpatent</B> zum Hauptpatent Nr. 219414.    Verfahren zur Herstellung eines     Nüpenfarbstoifes.       Es wurde gefunden,     dass    ein     wertvoller          Küpenfarbstoff    hergestellt werden kann,  wenn man 1     Mol    der nach dem Verfahren der       schweiz.    Patentschrift Nr.<B>208531</B> erhält  lichen     Fluoranthendicarbonsäure    oder eines  ihrer funktionellen Derivate mit 2     Mol          4-Amino-1,9-anthrapyrimidin    umsetzt.  



  Der neue Farbstoff stellt ein gelbes Pul  ver dar, das sieh in     konzentrierter    Schwefel  säure mit roter Farbe löst, sich bei 400   zer  setzt und Baumwolle aus brauner     Küpe    in       grünstiohiggelben    Tönen färbt.  



  Als funktionelle     Derivate    der     Fluor-          anthendicarbonsäure    werden zweckmässig  ihre     Dihalagenide,    insbesondere das     Di-          chlorid,    .das durch Behandeln der freien     Di-          carb.onsäure    mit z. B.     Thionylchlorid    erhält  lich ist, verwendet.  



  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     Ab-destillie-          ren    des     unverbrauchten        Thionylchlorids    lässt  man bei 150   eine     heisse    Lösung von 24,7 Tei  len     4-Amino-1,9-anthrapyrimidin    in<B>350</B> Tei  len     Dichlorbenzol        zufliessen.    Nach zweistün  digem     Rühren    bei     150-160'    ist die     Farb-          stoffbildung    beendet. Man saugt in der  Wärme ab, wäscht mit     Dichlorbenzol    und  Alkohol aus und trocknet.



  <B> Additional patent </B> to main patent no. 219414. Process for the production of a pomaceous dye. It has been found that a valuable vat dye can be produced if 1 mole of the can be produced using the Swiss method. Patent No. 208531 obtained by converting fluoranthendicarboxylic acid or one of its functional derivatives with 2 moles of 4-amino-1,9-anthrapyrimidine.



  The new dye is a yellow powder that dissolves in concentrated sulfuric acid with a red color, decomposes at 400 and dyes cotton from a brown vat in greenish-yellow tones.



  Its dihalogenides, in particular the dichloride, are expediently used as functional derivatives of fluoranthendicarboxylic acid. B. thionyl chloride is available Lich is used.



  The reaction is advantageously carried out by heating the components in solvents or diluents, such as. B. Di- or trichlorobenzene, 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 24.7 parts of 4-amino-1,9-anthrapyrimidine in 350 parts of dichlorobenzene is allowed to flow in at 150. After two hours of stirring at 150-160 ', the formation of the dye has ended. It is suctioned off in the heat, washed with dichlorobenzene and alcohol and dried.
