Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 257722.    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     des technischen Gemisches von     1-Amino-6-          und        -7-chloranthrachinon    der Formel  
EMI0001.0008     
    mit     earbazolierenden    Mitteln behandelt.

    Der neue Farbstoff     ist    ein dunkles Pulver,  das sich in konzentrierter Schwefelsäure mit  brauner Farbe löst und Baumwolle aus rot  brauner     Küpe    in     gelbstichigen    Brauntönen  färbt.  



  <I>Beispiel:</I>  60 Teile Aluminiumchlorid werden in 130  Teile trockenes     Pyridin    eingetragen und 10  Teile     Pyridin        abdestillieren    gelassen. Bei  einer Temperatur von 121-123  werden 6  Teile des     Kondensationsproduktes    aus 1     Mol            3',6'-Diehlor-3,4-phthaloyl-pyren    und 2     Mol     des technischen Gemisches von     1-Amino-6-          und    - 7 -     chloranthrachinon    zugefügt und  1 Stunde bei dieser Temperatur gerührt.

   Die  Schmelze wird in Wasser ausgetragen, mit  Natronlauge alkalisch gestellt, mit     Natrium-          hydrosulfit        verküpt    und von wenig Verunrei  nigungen     abfiltriert.    Nach dem Ausblasen  mit Luft,     Abfiltrieren,    Auswaschen und  Trocknen stellt der Farbstoff ein dunkles  Pulver dar.



  <B> Additional patent </B> to the main patent No. 257722. It has been found that a valuable vat dye can be produced if the condensation product is made from 1 mole of 3 ', 6'-dichloro-3,4-phthaloyl-pyrene and 2 Mol of the technical mixture of 1-amino-6- and -7-chloranthraquinone of the formula
EMI0001.0008
    treated with earbazolating agents.

    The new dye is a dark powder that dissolves in concentrated sulfuric acid with a brown color and dyes cotton from a red-brown vat in yellowish 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 121-123 6 parts of the condensation product of 1 mole of 3 ', 6'-diehlor-3,4-phthaloyl-pyrene and 2 moles of the technical mixture of 1-amino-6 and 7-chloroanthraquinone are added and Stirred for 1 hour at this temperature.

   The melt is poured into water, made alkaline with sodium hydroxide solution, vat with sodium hydrosulphite and a few impurities are filtered off. After blowing out with air, filtering off, washing out and drying, the dye is a dark powder.
