Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 189649.    Verfahren zur Herstellung eines sauren     Wollfarbstoffes.       Gegenstand des vorliegenden Patentes     ist     ein Verfahren zur     Herstellung    eines sauren       Wollfarbstoffes,    das dadurch ,gekennzeichnet  ist, dass man den Farbstoff der     Formel     
EMI0001.0006     
    mit einem     sulfonierenden        Mittel    behandelt.

    Der neue Farbstoff, der zwei     Sulfogrup-          pen    im Molekül enthält, färbt Wolle in kla  ren,     grünstichig    blauen Tönen von guter  Licht- und     Alkalieohtheit    und     gutem        Egali-          sierungsvermögen,            Beispiel:     Zwecks     Sulfonierung        wird,der    Farbstoff  der Formel:

    
EMI0001.0019     
    mit der fünffachen Menge 3'2     %igen        Oleums     mehrere     Stunden    auf<B>80'</B> erhitzt,     bis    eine  Probe sich in verdünnter     Natriumacetatlösung     klar löst. Die Aufarbeitung und     Überfülh-          rung        in    das     Natriumsalz        erfolgt    in üblicher  Weise.

   Der Farbstoff enthält zwei     Sulfo-          gruppen    im     Molekül.    Er färbt Wolle in  klaren,     grünstichig    blauen Tönen von guter  Licht- und     Alka,1iechtheit        qnd        gutem        Egali-          sierungsvermö;gen,  



  <B> Additional patent </B> to main patent No. 189649. Process for the production of an acidic wool dye. The present patent relates to a process for the preparation of an acidic wool dye, which is characterized in that the dye of the formula
EMI0001.0006
    treated with a sulfonating agent.

    The new dye, which contains two sulpho groups in the molecule, dyes wool in clear, greenish blue tones of good light and alkali fastness and good leveling properties, for example: For sulphonation, the dye of the formula:

    
EMI0001.0019
    heated with five times the amount of 3'2% oleum for several hours to <B> 80 '</B> until a sample dissolves clearly in dilute sodium acetate solution. The work-up and conversion into the sodium salt is carried out in the usual way.

   The dye contains two sulfo groups in the molecule. It dyes wool in clear, greenish blue tones of good lightness and alkali, lautness and good leveling power;
