Description

  

      Zusatzpatent    zum     Hauptpatent    Nr. 189649.         Verfahren    zur Herstellung eines     sauren        Wollfarbstoffes.            Gegenstand    des vorliegenden Patentes ist  ein Verfahren zur Herstellung eines sauren  Wollfarbstoffes. Dieses ist dadurch .gekenn  zeichnet, dass man den     Farbstoff    der Formel  
EMI0001.0008     
    mit einem     sulfonierenden        Mittel    behandelt.

    Der erhaltene neue Farbstoff, der zwei       Sulfogruppen    im Molekül enthält, zeigt hin  sichtlich seiner     färberischen        Eigenschaften     weitgehende Ähnlichkeit mit :demjenigen des       Hauptpatentes.       <I>Beispiel:

  </I>  Der Farbstoff .der Formel  
EMI0001.0015     
         wird    zwecks     Sulfonierung    in     die        fünffache     Menge     d0        %        ixen        Oleums        eingetragen    und  mehrere     Stunden    auf<B>80'</B>     erhitzt,

          bis    eine  Probe in wässriger     Natriumacetatlösung    klar  löslich     ist.    Die     Aufarbeitung        erfolgt    in übli  cher     Weise    durch     Ausgiessen    auf Eis, Filtra  tion und Überführung in     das        Natronsalz.    Der       erhaltene        Farbstoff        enthält    zwei     @Sulfogrup-          pen    im Molekül.

   Er färbt Wolle     in,    klaren,  grünstickig blauen Tönen von     .guter        Licht-          und        Alkaliechtheit.  



      Additional patent to main patent No. 189649. Process for the production of an acidic wool dye. The subject of the present patent is a process for the production of an acidic wool dye. This is characterized by the fact that one uses the dye of the formula
EMI0001.0008
    treated with a sulfonating agent.

    The new dye obtained, which contains two sulfo groups in the molecule, shows in terms of its coloring properties extensive similarity with: that of the main patent. <I> example:

  </I> The dye. Of the formula
EMI0001.0015
         for the purpose of sulfonation, five times the amount of d0% ixen oleum is added and heated to <B> 80 '</B> for several hours,

          until a sample is clearly soluble in aqueous sodium acetate solution. Working up is carried out in a customary manner by pouring onto ice, filtration and conversion into the sodium salt. The dye obtained contains two sulfo groups in the molecule.

   It dyes wool in clear, greenish blue tones of good light and alkali fastness.
