Description

  

  <B>Zusatzpatent</B> zum     Hauptpatent    Nr. 7.89649.    Verfahren zur Herstellung eines sauren     Wollfarbstoffes.       Gegenstand vorliegenden Patentes ist ein  Verfahren zur Herstellung eines sauren  Wollfarbstoffes, das dadurch gekennzeichnet  ist, dass man den Farbstoff der Formel:  
EMI0001.0003     
    mit einem sulfonierenden     Mittel    behandelt.  Der neue Farbstoff, der zwei     Sulfogrup-          pen    im Molekül enthält, färbt Wolle in rot  stichig blauen Tönen von guter Alkali- und  Lichtechtheit.

      <I>Beispiel:</I>  Das     Safranin    der Formel:  
EMI0001.0008     
    das erhältlich ist durch     Zusammenogydieren     des     Isorosindulins    aus     vic.        m-Xylyl-ss-naph-          thylamin    und     Nitrosocyclohegyläthylanilin     mit     Xylylendiamin    wird in der fünffachen  Menge 32 %     igen        Oleums    mehrere Stunden  auf<B>80'</B> C erhitzt, bis eine Probe sich in ver  dünnter     Natriumacetatlösung        ohne    Rück  stand löst.

   Die Aufarbeitung erfolgt in übli  cher Weise durch     Ausgiessen    auf Eis,     Fil-          trieren    und     Überführung        in    das     Natronsalz.     



  Der erhaltene Farbstoff enthält zwei       Sulfogruppen    im Molekül. Er färbt Wolle      in     rotstichig    blauen Tönen von guter     Alkali-          und    Lichtechtheit.



  <B> Additional patent </B> to main patent No. 7.89649. 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:
EMI0001.0003
    treated with a sulfonating agent. The new dye, which contains two sulfo groups in the molecule, dyes wool in red, blue tones with good alkali and lightfastness.

      <I> Example: </I> The Safranin formula:
EMI0001.0008
    which is obtainable by togetherogydating the isorosindulin from vic. m-Xylyl-ss-naphthylamine and nitrosocyclohegylethylaniline with xylylenediamine is heated in five times the amount of 32% oleum for several hours at <B> 80 ° C, until a sample dissolves in dilute sodium acetate solution without residue.

   Working up is carried out in the usual way by pouring onto ice, filtering and converting into the sodium salt.



  The dye obtained contains two sulfo groups in the molecule. It dyes wool in reddish blue tones with good alkali and lightfastness.
