Description

  

      Zusatzpatent    zum Hauptpatent Nr. 153492.    Verfahren zur Darstellung eines     stickstoffhaltigen        Anthrachinonderivates.       Es wurde gefunden, dass man einen grü  nen     Acetatseidefarbstoff    erhält, wenn man       1-Oxy-4,    5,     8-triaminoanthrachinon    als     Leuko-          derivat    unter Zusatz von Borsäure in orga  nischen Lösungsmitteln mit     p-Aminophenol     in Gegenwart von     p-Aminophenolchlorhydrat     kondensiert,

   wobei sehr wahrscheinlich 2     Mol          p-Aminophenol    mit einem     Mol        1-Oxy-4,5,8-          triaminoanthrachinon    reagieren. Das Konden  sationsprodukt löst sich in organischen Lö  sungsmitteln mit grüner Farbe und färbt       Acetatseide    nach geeigneter     Verpastung    in  grünen Tönen von vorzüglicher Echtheit.

      <I>Beispiel:</I>  30 Teile reines     1-Oxy-4,5,8-triaminoanthra-          chinon    werden in 200 Teilen Alkohol mit  40 Teilen     p-Aminophenol,    30 Teilen Borsäure,  15 Teilen     p-Aminophenolchlorhydrat    und 15  Teilen     Natriumhydrosulfit    zum Kochen er  hitzt, bis eine Probe, in Alkohol gelöst, keine  weitere Verschiebung der Farbe nach Grün    aufweist. Man filtriert kalt, wäscht den Rück  stand mit Alkohol und Wasser aus.  



  Man kann auch     Leuko-l-oxy-4,    5,     8-tri-          aminoanthrachinon    ohne Zusatz von Reduk  tionsmitteln zur Kondensation verwenden.



      Additional patent to main patent No. 153492. Process for the preparation of a nitrogen-containing anthraquinone derivative. It has been found that a green acetate silk dye is obtained if 1-oxy-4, 5, 8-triaminoanthraquinone is condensed as a leuco derivative with the addition of boric acid in organic solvents with p-aminophenol in the presence of p-aminophenol chlorohydrate,

   2 moles of p-aminophenol reacting with one mole of 1-oxy-4,5,8-triaminoanthraquinone very likely. The condensation product dissolves in organic solvents with a green color and, after suitable pasting, dyes acetate silk in green shades of excellent fastness.

      <I> Example: </I> 30 parts of pure 1-oxy-4,5,8-triaminoanthraquinone in 200 parts of alcohol with 40 parts of p-aminophenol, 30 parts of boric acid, 15 parts of p-aminophenol chlorohydrate and 15 parts of sodium hydrosulfite to boil it is heated until a sample, dissolved in alcohol, shows no further shift in color to green. It is filtered cold, the residue was washed with alcohol and water.



  You can also use leuco-l-oxy-4, 5, 8-tri-aminoanthraquinone without the addition of reducing agents for condensation.

PATENTANSPRUCH: Verfahren zur Darstellung eines Farbstof fes der Anthrachinonreihe, dadurch gekenn zeichnet, dass man Leuko-l-oxy-4,5,8-triamino- anthrachinon in organischen Lösungsmitteln in Gegenwart von Borsäure und p-Amino- phenolchlorhydrat mit p-Aminophenol kon densiert. Der erhaltene Farbstoff löst sich in orga nischen Lösungsmitteln mit grüner Farbe und färbt Acetatseide nach geeigneter Ver- pastung in grünen Tönen von vorzüglicher Echtheit. PATENT CLAIM: Process for the preparation of a dye of the anthraquinone series, characterized in that leuco-l-oxy-4,5,8-triamino anthraquinone in organic solvents in the presence of boric acid and p-aminophenol chlorohydrate with p-aminophenol con condensed. The dye obtained dissolves in organic solvents with a green color and, after suitable pasting, dyes acetate silk in green shades of excellent fastness.
