  <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'-1)ilialogen-3,4-phthaloyl-pyren    und  2     Mol        1-Aininoanthrachinon    mit     carbazolieren-          den    Mitteln behandelt und auf das Reaktions  produkt in Gegenwart von     Ahtminiumehlorid          Benzoylchlorid    bei erhöhter Temperatur ein  wirken lässt.  



  Der neue Farbstoff ist ein dunkles Pulver,  das sich in     konz.    Schwefelsäure mit schmutzig  violetter Farbe löst und Baumwolle aus     röt-          lichbrauner        Küpe    in     olivbraunen    Tönen färbt.  <I>Beispiel:</I>  60 Teile Aluminiumchlorid werden in 130  Teile trockenes     Pyridin    eingetragen und 10  Teile     Pyridin        abdestillieren    gelassen.

   Bei einer  Temperatur von 121 bis 1230 werden 6 Teile  des Kondensationsproduktes aus 1     Mol        3',6'-          1)ihalogen-3,4-phthaloyl-pyren    und 2     Mol        1-          Aminoanthrachion    zugefügt und eine Stunde  bei dieser Temperatur gerührt.

   Die Schmelze  wird in     Wasser    ausgetragen, mit Natronlauge  alkalisch gestellt, mit     Natriumhydrosulfit        ver-          kül>t    und von wenig Verunreinigungen     abfil-          triert.    Nach dem Ausblasen mit Luft,     Abfil-          trieren,    Auswaschen und Trocknen stellt der  Farbstoff ein dunkles Pulver dar.    1,5 Teile dieses Farbstoffes und 1,0 Teil       Benzoylehlorid    werden bei 112 bis 1170 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 zwei Stun  den bei dieser Temperatur gerührt, wobei  noch Luft durchgeblasen wird. Nach dem Er  kalten wird die Reaktionsmasse zerkleinert, in  verdünnte Salzsäure eingetragen,     abgenutseht,     ausgewaschen und mit verdünnter     Sodalösung          ausgekocht.  



  <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 1st mole of 3 ', 6'-1) ilialogen-3,4-phthaloyl-pyrene and 2 moles of 1-aminoanthraquinone is treated with carbazolating agents and can act on the reaction product in the presence of Ahtminiumehlorid benzoyl chloride at an elevated temperature.



  The new dye is a dark powder that is in conc. Sulfuric acid dissolves with a dirty violet color and dyes cotton from a reddish-brown vat in olive-brown tones. <I> Example: </I> 60 parts of aluminum chloride are introduced into 130 parts of dry pyridine and 10 parts of pyridine are allowed to distill off.

   At a temperature of 121 to 1230 6 parts of the condensation product of 1 mol of 3 ', 6'- 1) ihalogen-3,4-phthaloyl-pyrene and 2 mol of 1-aminoanthraquinone are added and the mixture is stirred at this temperature for one hour.

   The melt is poured into water, made alkaline with sodium hydroxide solution, encapsulated with sodium hydrosulphite and a few impurities are filtered off. After blowing out with air, filtering off, washing out and drying, the dyestuff is a dark powder. 1.5 parts of this dyestuff and 1.0 part of benzoyl chloride are added at 112 to 1170 to a melt of 25 parts of aluminum chloride, 5 parts of potassium chloride and 3.5 parts of sodium chloride entered.

   The temperature is then increased to 1400 and stirred for two hours at this temperature, with air being blown through. After he cold, the reaction mass is crushed, added to dilute hydrochloric acid, removed, washed and boiled with dilute soda solution.
