Description

  

  <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'-Dihalogen-monophthaloyl-pyren    und 2       Mol        5-Amino-1,1'-dianthrimid    der Formel  
EMI0001.0009     
    mit     carbazolierenden    Mitteln behandelt.  



  Der neue Farbstoff ist ein     braunschwarzes     Pulver, das sich in     konz.    Schwefelsäure mit       schmutzig    violetter Farbe löst und Baumwolle  aus rotbrauner     Küpe    in     gelbstichig    braunen  Tönen färbt.  



  <I>Beispiel:</I>  30 Teile Aluminiumchlorid und 3,6 Teile  Kochsalz werden innig vermischt und bei 1400  verschmolzen. Nun werden bei 140 bis 1450  1,5 Teile des     Kondensationsproduktes    aus       3',6'-Dichlor-3,4-monophthaloyl-pyren    und     5-          Amino-1,1'-dianthrimid    eingetragen und zwei  Stunden bei 165 bis 1680 gerührt. Nach dem  Austragen in Eis und Wasser wird mit ver  dünnter Schwefelsäure angesäuert und mit    0,9 Teilen     Natriumdichromat    bei gewöhnlicher  Temperatur nachoxydiert.  



  Das hier verwendete Kondensationspro  dukt kann aus 1     Mol        3',6'-Dichlor-3,4-mono-          phthaloyl-pyren    und 2     Mol        5-Amino-1,1'-di-          anthrimid    unter Zusatz von Kupfersalzen in  siedendem Nitrobenzol in üblicher Weise her  gestellt werden.



  <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 prepared if the condensation product of 1 mole of 3 ', 6'-dihalo-monophthaloyl-pyrene and 2 moles of 5-amino-1,1'-dianthrimide of the formula
EMI0001.0009
    treated with carbazolating agents.



  The new dye is a brown-black powder, which is in conc. Sulfuric acid dissolves with a dirty purple color and dyes cotton from a reddish brown vat in yellowish brown tones.



  <I> Example: </I> 30 parts of aluminum chloride and 3.6 parts of table salt are intimately mixed and fused at 1400. 1.5 parts of the condensation product of 3 ', 6'-dichloro-3,4-monophthaloyl-pyrene and 5-amino-1,1'-dianthrimide are then introduced at 140 to 1450 and the mixture is stirred at 165 to 1680 for two hours. After pouring into ice and water, the mixture is acidified with dilute sulfuric acid and post-oxidized with 0.9 parts of sodium dichromate at ordinary temperature.



  The condensation product used here can be prepared from 1 mole of 3 ', 6'-dichloro-3,4-monophthaloyl-pyrene and 2 moles of 5-amino-1,1'-di-anthrimide with the addition of copper salts in boiling nitrobenzene in the usual way Way to be made.
