      Zusatzpatent    zum Hauptpatent Nr. 257722.    Verfahren zur Herstellung eines     Küpenfarbstoffes.       Es wurde gefunden, dass ein wertvoller       Küpenfarbstoff    hergestellt werden kann, wenn  man das Kondensationsprodukt. aus 1.     Mol          3',6'-Diehlorphthaloylfluorantlien    und 2     1Io1          1-Amino-5-benzoylamiiioanthrachinoii    mit     car-          bazolierenden    Mitteln behandelt.  



  Der neue Farbstoff ist ein dunkles Pulver,  das Baumwolle aus oliver     Küpe    in schwärz  liehbraunen Tönen färbt.  



  <I>Beispiel:</I>       Eine    innige Mischung von 25 Teilen Alu  miniumchlorid und 4 Teilen     Natriumchlorid     wird durch Einleiten von Schwefeldioxyd ver  flüssigt. In die entstandene Schmelze trägt  man nun 2 Teile des     Kondensationsproduktes     aus 1     Mol        3',6'-Dichlorphthaloylfluoranthen     und 2     Mol        1-Amino-5-benzoylaminoant.hrachi-          non    ein. Nach je einstündigem Rühren bei 40  bis 450 und 85 bis 900 ist die Reaktion beendet.

    Man trägt das Umsetzungsgemisch auf Eis  aus, gibt 20 Teile konzentrierte Salzsäure         hinzu,    erhitzt zum Sieden und saugt den aus  gefallenen Farbstoff ab. Er wird säurefrei  gewaschen und anschliessend in 200 Teilen  5     ?G        iger    Schwefelsäure verteilt. Man kühlt  nun auf 0 bis 5  ab, gibt 0,6 Teile Natrium  nitrit zu und rührt die     Suspension    mehrere  Stunden bei 0 bis 50. Der so erhaltene Farb  stoff wird abgesaugt, gewaschen und mit  Wasser v     erpastet.  



      Additional patent to main patent No. 257722. Process for the production of a vat dye. It has been found that a valuable vat dye can be made by using the condensation product. of 1. Mol 3 ', 6'-Diehlorphthaloylfluorantlien and 2 1Io1 1-Amino-5-benzoylamiiioanthrachinoii treated with carbazolating agents.



  The new dye is a dark powder that dyes cotton from an olive vat in blackish brown tones.



  <I> Example: </I> An intimate mixture of 25 parts of aluminum chloride and 4 parts of sodium chloride is liquefied by introducing sulfur dioxide. 2 parts of the condensation product of 1 mole of 3 ', 6'-dichlorophthaloyl fluoranthene and 2 moles of 1-amino-5-benzoylaminoanthrachinone are then introduced into the melt formed. After stirring for one hour at 40 to 450 and 85 to 900, the reaction is complete.

    The reaction mixture is discharged onto ice, 20 parts of concentrated hydrochloric acid are added, the mixture is heated to boiling and the dyestuff which has precipitated out is filtered off with suction. It is washed free of acid and then distributed in 200 parts of 5% sulfuric acid. It is then cooled to 0 to 5, 0.6 part of sodium nitrite is added and the suspension is stirred for several hours at 0 to 50. The dye thus obtained is filtered off with suction, washed and pasted with water.
