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'-Dihalogen-3,4-phthaloyl-pyren    und  2     Mol        1-Aminoanthrachinon    mit     carbazolie-          renden    Mitteln behandelt und auf das Reak  tionsprodukt in Gegenwart von Aluminium  chlorid     Phthalsäureanhydrid    bei erhöhter  Temperatur einwirken lässt.  



  Der neue Farbstoff ist ein dunkles Pulver,  das sich in     konz.    Schwefelsäure mit grau  blauer Farbe löst und Baumwolle aus violett  brauner     Küpe    in     schwärzlichbraunen    Tönen  färbt.  



       Beispiel:     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'-          Dihalogen-3,4-phthaloyl-pyren    und 2     Mol        1-          Aminoanthrachinon    zugefügt und eine Stunde  bei dieser Temperatur gerührt.

   Die Schmelze  wird in Wasser ausgetragen, mit Natronlauge  alkalisch gestellt, mit     Natriumhydrosulfit        ver-          küpt    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 3 Teile       Phthalsäureanhydrid    werden bei 112 bis 1170  in eine Schmelze von 25 Teilen Aluminium  chlorid, 5 Teilen     Kaliumchlorid    und 3,5 Tei  len     Natriumchlorid    eingetragen.

   Hierauf wird  die Temperatur erhöht und sechs bis acht  Stunden bei 125 bis<B>1500</B> gerührt. Nach dem  Erkalten wird die Reaktionsmasse zerkleinert,  in verdünnte Salzsäure eingetragen,     abge-          nutscht,    ausgewaschen und mit. verdünnter       Sodalösung    ausgekocht.



  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'-dihalo-3,4-phthaloyl-pyrene and 2 moles of 1-aminoanthraquinone is treated with carbazolizing agents and the reac tion product in the presence of aluminum chloride allows phthalic anhydride to act at an elevated temperature.



  The new dye is a dark powder that is in conc. Sulfuric acid dissolves with a gray-blue color and dyes cotton from a purple-brown vat in blackish-brown tones.



       Example: 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 mole of 3 ', 6'-dihalo-3,4-phthaloyl-pyrene and 2 moles 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, vat with sodium hydrosulfite and a little impurities are filtered off. After blowing out with air, filtering off, washing out and drying, the dye is a dark powder. 1.5 parts of this dye and 3 parts of phthalic anhydride are 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 entered.

   The temperature is then increased and the mixture is stirred for six to eight hours at 125 to 1500. After cooling, the reaction mass is crushed, introduced into dilute hydrochloric acid, filtered off with suction, washed out and mixed with. diluted soda solution.
