Description

  

  <B>Zusatzpatent</B>     zum    Hauptpatent Nr. 257722.    Verfahren zur Herstellung eines     Küpenfarbatoffes.       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  Amino-1,1'-dianthrimid mit     carbazolierenden     Mitteln behandelt und auf das Reaktionspro  dukt in Gegenwart von Aluminiumchlorid       Benzoylchlorid    bei erhöhter Temperatur ein  wirken lässt.  



  Der neue Farbstoff ist ein dunkles Pulver,  das sich in     konz.    Schwefelsäure mit schmutzig  braunvioletter Farbe löst und     Baumwolle    aus       brauner        Küpe    in braunschwarzen Tönen  färbt.  



  <I>Beispiel:</I>  1,5 Teile des     Kondensationsproduktes    aus  1     Mol        3',6'-Dichlor-3,4-phthaloyl-pyren    und  2     Mol        4-Amino-1,1'-dianthrimid,werden.bei   <B>1000</B>  in eine Schmelze von 20 Teilen Aluminium  chlorid und 50 Teilen trockenem     Pyridin    ein  getragen. Nun erhöht man die Temperatur  unter gleichzeitigem     Abdestillieren    eines Teils  des     Pyridins    in einer halben Stunde auf 140  bis 1420 und rührt eine weitere halbe Stunde  bei dieser Temperatur.

   Die     Schmelze    wird  hierauf in Wasser     ausgetragen,    mit Natron  lauge alkalisch gestellt und mit     Hydrosulfit          verküpt.    Nach der Filtration von wenig Rück  stand wird der Farbstoff mit Luft ausgebla-         sen,        abgenutscht,    ausgewaschen und getrock  net,.  



  1,5 Teile dieses Farbstoffes und 1,0 Teile       Fenzoylchlorid    werden bei 112 bis<B>1170</B> in eine       Schmelze    von 25 Teilen Aluminiumchlorid,  5 Teilen     Kaliumchlorid    und 3,5 Teilen Na  triumchlorid eingetragen. Hierauf wird die  Temperatur auf 1400 erhöht und 2 Stunden  bei dieser Temperatur gerührt, wobei noch  Luft durchgeblasen wird. Nach dem Erkalten  wird die Reaktionsmasse zerkleinert, in ver  dünnte Salzsäure eingetragen,     abgenutscht,     ausgewaschen und mit verdünnter Natron  lauge ausgekocht.



  <B> Additional patent </B> to main patent no. 257722. Process for the production of a vat colorant. It has been found that a valuable vat dye can be made by treating the condensation product of 1 mole of 3 ', 6'-dichloro-3,4-phthaloyl-pyrene and 2 moles of 4-amino-1,1'-dianthrimide with carbazolating agents and on the reaction product in the presence of aluminum chloride benzoyl chloride at an elevated temperature can act.



  The new dye is a dark powder that is in conc. Sulfuric acid dissolves with a dirty brown-violet color and dyes cotton from a brown vat in brown-black tones.



  <I> Example: </I> 1.5 parts of the condensation product from 1 mol of 3 ', 6'-dichloro-3,4-phthaloyl-pyrene and 2 mol of 4-amino-1,1'-dianthrimide are used <B> 1000 </B> carried into a melt of 20 parts of aluminum chloride and 50 parts of dry pyridine. The temperature is now increased to 140 to 1420 in half an hour, while part of the pyridine is distilled off at the same time, and the mixture is stirred at this temperature for another half hour.

   The melt is then discharged into water, made alkaline with sodium hydroxide solution and vat with hydrosulfite. After a little residue has been filtered off, the dye is blown out with air, suction filtered, washed out and dried.



  1.5 parts of this dye and 1.0 part of fenzoyl chloride are entered at 112 to 1170 in a melt of 25 parts of aluminum chloride, 5 parts of potassium chloride and 3.5 parts of sodium chloride. The temperature is then increased to 1400 and stirred for 2 hours at this temperature, while air is still blown through. After cooling, the reaction mass is crushed, added to dilute hydrochloric acid, suction filtered, washed and boiled with dilute sodium hydroxide solution.
