Description

  

      Verfahren        zur    Herstellung eines     Küpenfarbstoffes.       Es wurde gefunden, dass ein wertvoller       Küpenfarbstoff    hergestellt werden kann, wenn  man das Kondensationsprodukt aus 1     Mol            3',6'-Dichlor-3,4-phthaloyl-pyren    und 2     Mol     4 -     Aminoanthrachinon-2,1-    (N)     -l',2'-    (N)     -benz-          acridon    der Formel  
EMI0001.0012     
    mit     carbazolierenden        Mitteln    behandelt.  



  Der neue Farbstoff ist ein     olivschwarzes          Pulver,    das sich in     konz.    Schwefelsäure mit.  braunschwarzer Farbe löst und Baumwolle  aus schwarzbrauner     Küpe    in reinen olivgrü  nen, sehr echten Tönen färbt.

      <I>Beispiel:</I>  12 Teile des in üblicher Weise aus 1     Mol          3',6'-Dichlor-3,4-phthaloyl-pyren    und 2     Mol          4--        Aminoanthrachinon-2,1-    (N) -1',2' - (N)     -benz-          acridon    erhaltene Kondensationsprodukt wer  den bei 1000 in eine Schmelze von 120 Teilen           Aluminiumchlorid    und 300 Teilen trockenem       Pyridin        eingetragen    und die     Temperatur    un  ter gleichzeitigem     Abdestillieren    von     Pyridin     auf 140 bis 1420 erhöht.

   Nach     33/.I    Stunden       Rühren    bei dieser Temperatur     wird    in Wasser  ausgetragen,     alkalisch    gestellt,     verküpt    und  von etwas Ungelöstem     abfiltriert.    Durch Aus  blasen mit Luft wird der Farbstoff als oliv  schwarzes Pulver erhalten.



      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'-dichloro-3,4-phthaloyl-pyrene and 2 moles of 4-aminoanthraquinone-2,1- (N) -l ', 2'- (N) -benz- acridone of the formula
EMI0001.0012
    treated with carbazolating agents.



  The new dye is an olive black powder, which is in conc. Sulfuric acid with. brown-black color dissolves and dyes cotton from a black-brown vat in pure olive-green, very real tones.

      <I> Example: </I> 12 parts of the conventionally prepared from 1 mol of 3 ', 6'-dichloro-3,4-phthaloyl-pyrene and 2 mol of 4-- aminoanthraquinone-2,1- (N) -1 ', 2' - (N) -benz- acridone obtained condensation product who entered at 1000 in a melt of 120 parts of aluminum chloride and 300 parts of dry pyridine and the temperature increased to 140 to 1420 under simultaneous distillation of pyridine.

   After 33 / .I hours of stirring at this temperature, the mixture is poured into water, made alkaline, evaporated and some undissolved material is filtered off. By blowing out with air, the dye is obtained as an olive black powder.
