Description

  

  <B>Zusatzpatent</B> 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'-Dichlorphthaloyl-fluoranthen    und  2     Mol        1-Aminoanthrachinon    der Formel  
EMI0001.0007     
    mit     carbazolierenden    Mitteln behandelt.  



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



  <I>Beispiel:</I>  2 Teile des     Kondensationsproduktes    aus  1     Mol        Dichlorphthaloyl-fluoranthen    und 2     Mol          1-Aminoanthrachinon    werden bei 125 bis 1350  in eine Schmelze aus 10 Teilen Aluminium-    Chlorid und 30 Teilen     Pyridin    eingetragen.  Nun erhöht man die Temperatur auf 150 bis  1600, wobei ein Teil des     Pyridins        abdestilliert.     Nach zweistündigem Rühren bei 150 bis 1600  ist die Reaktion beendet.

   Die Schmelze wird  in 1000 Teile 5 %     iger    Natronlauge eingerührt,       verküpt    und von geringen Mengen Unlös  lichem     abfiltriert.    Der durch Einleiten von  Luft vollständig ausgefällte Farbstoff wird  abgesaugt, gewaschen und getrocknet.



  <B> Additional patent </B> to main patent No. 257722. Process for the production of a vat dye. It has been found that a valuable vat dye can be produced if the condensation product of 1 mole of 3 ', 6'-dichlorophthaloyl fluoranthene and 2 moles of 1-aminoanthraquinone of the formula
EMI0001.0007
    treated with carbazolating agents.



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



  <I> Example: </I> 2 parts of the condensation product of 1 mole of dichlorophthaloyl fluoranthene and 2 moles of 1-aminoanthraquinone are introduced into a melt of 10 parts of aluminum chloride and 30 parts of pyridine at 125 to 1350. The temperature is now increased to 150 to 1600, with part of the pyridine distilling off. After two hours of stirring at 150 to 1600, the reaction has ended.

   The melt is stirred into 1000 parts of 5% sodium hydroxide solution, vat and small amounts of insoluble matter are filtered off. The dye, which is completely precipitated by the introduction of air, is filtered off with suction, washed and dried.
