Description

  

  Verfahren zur Herstellung eines     Farbstoffe-s    der     Plienyldinahhtylnietlianreihe.       Es wurde-     gefunden,        dass,        wenn    man     a12'          1-Naphtol-2-e,rbonsäiire        4-Clilorbenzoltri-          chlorid    in     (-T'e"enwart    eines     säurebindenden     Mittels.

       vorzugsweise        unter        Zugabe    eines       Katalysators,        einwirken    lässt, ein neuer     Farb-          toff        erhalten    wird. Dieser Farbstoff gibt  s<B>s</B>  auf Wolle, aus     saurein    Bade gefärbt eine  graue Färbung, welche     beine        Nachchroniieren     in ein reines.     N-        orzüglicli    echtes Grün über  geht.

           Beispiel:     752 Teile     1-Naphtol-2-carlionsäure        -,ver-          den    - in 1900 Teilen     Natronlauge        von    30       Gew.    und 500 Teilen     -\Vasser    gelöst. Hier  auf gibt     inan    ! 34 Teile     4-Clilorbenzotrichlorid     und 0,5 Teile Kupfer     hinzu    und rührt so  lange, bis alles     Benzotriclilorid        verschwunden     ist.

   Das     Natriumsalz    des gebildeten Farb  stoffes wird     durch        Aussalzen    aus dein mit  Wasser verdünnten Reaktionsgemisch abge  schieden.



  Process for the preparation of a dye of the Plienyldinahhtylnietlian reason. It has been found that if one converts a12 '1-naphthol-2-e, carbonic acid 4-chlorobenzene trichloride into (-T'e "in the presence of an acid-binding agent.

       preferably with the addition of a catalyst, a new dye is obtained. This dye gives s <B> s </B> on wool, dyed from acidic bath a gray color, which is followed by post-chronizing into a pure. N- orzüglicli real green goes over.

           Example: 752 parts of 1-naphthol-2-carlionic acid - dissolved in 1900 parts of 30% by weight sodium hydroxide solution and 500 parts of water. Give up here! Add 34 parts of 4-chlorobenzotrichloride and 0.5 part of copper and stir until all the benzotricliloride has disappeared.

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