      Verfahren    zur Herstellung     eines        Farbstoffes    der     Plienyldinaplitylinetlianreilie.       Es wurde gefunden, dass, wenn man     aul'          1-Naphtol-2-carbonsziure        2-Clilorbciizotriclilo-          rid    in Gegenwart     eines        s:

  iurebinclenden    Mit  tels,     vorzugsweise        unter        Zugabe    eines     I-a          talysators,        einwirhen        1At,    ein neuer Farb  stoff erhalten wird. Dieser Farbstoff gibt auf  Wolle, aus saurem Bade     gefiirbt,    eine     grauci          Färbung,    welche beim     Nacliebromieren    in ein  reines,     vorzüglich    echtes Grün     übergebt.     



  <I>Beispiel:</I>  752 Teile     1-Naplitol-2-carbonsälire    werden  in 1900 Teilen     Natronlauge    von 30 %     Gew.          und    500 Teilen Wasser     (relüst.        Vierau('        gibt:     man     -I2-1    Teile     2-Chloi-heiizotricblorid    und  0,5 Teile     Kulifer        hinzu        und    rührt so lange.  bis alles     Benzotrieblorid    verschwunden ist.

    Das     Natriumsalz    des     :;gebildeten        Farbstoffes     wird durch     Aussalzen    aus dem mit Wasser  verdünnten Reaktionsgemisch abgeschieden.



      Process for the preparation of a dye of the Plienyldinaplitylinetlianreilie. It has been found that if aul '1-naphthol-2-carboxylic acid 2-Clilorbciizotriclilorrid in the presence of a s:

  iurebinclenden agent, preferably with the addition of an I-a catalyst, twist in 1At, a new dye is obtained. This dye gives wool, dyed from an acid bath, a gray color which, when brominated, turns into a pure, exquisitely true green.



  <I> Example: </I> 752 parts of 1-naplitol-2-carbonsälire are dissolved in 1900 parts of sodium hydroxide solution of 30% by weight and 500 parts of water (reluest. Add hot tricbloride and 0.5 parts of cooler and stir until all of the benzotricbloride has disappeared.

    The sodium salt of the dye formed is deposited by salting out from the reaction mixture diluted with water.
