Description

  

  Verfahren zur Darstellung eines grünen     Schwefelfarbstoffes.       Nach dem     im    Hauptpatent beschriebenen  Verfahren erhält man einen grünen Schwefel  farbstoff,     wennmandas    aus     3.4.5.6-Dinaphtho-          carbazol        durch    Umsetzung mit     Chinonchlor-          imid        bezw.        Nitrosophenol        erhältliche        Leuko-          indophenol    in Gegenwart eines Verdünnungs  mittels der     Verschwefelung    unterwirft.  



  Wie nun weiter     gefunden    wurde, erhält  man einen     ähnlichen    Farbstoff, wenn man das       Leukoindophenol,    das aus     N-Methyl-3.4.    5 .     6-          dinaphthocarbazol    mit     Chinonchlorimid        bezw.          Nitrosophenol    erhalten wird, der     Verschwefe-          lung        unterwirft.            Beispiel   <I>3:</I>    s Man erhitzt das nach Beispiel 3 des Schweiz.

    Patentes Nr. 206720 hergestellte     Leukoindo-          phenol    aus 14 Teilen     N-Methyl-3.4.5.6-          dinaphthocarbazol    mit einer     Polysulfidlösung     aus 12 Teilen konzentriertem     Schwefelnatrium,     14,5     Teilen    Schwefel, 50     Volumteilen        Alkohol     und 3     Teilen    Kupferbronze etwa 50     Stundenzum       Sieden und     arbeitet    wie üblich auf.

   Der ge  bildete     Farbstoff    färbt Baumwolle aus     schwefel-          natriumhaltiger    Flotte     in    grünen Tönen.



  Process for the preparation of a green sulfur dye. According to the process described in the main patent, a green sulfur dye is obtained if the mixture is obtained from 3.4.5.6-dinaphtho-carbazole by reaction with quinone chloroimide or. Nitrosophenol available leuco indophenol in the presence of a diluent by means of the sulfurization.



  As has now been found, a similar dye is obtained if the leucoindophenol, which is obtained from N-methyl-3.4. 5. 6- dinaphthocarbazole with quinone chlorimide respectively. Nitrosophenol is obtained, which subjects to sulphurisation. Example <I> 3: </I> s This is heated according to example 3 of Switzerland.

    Patent No. 206720 produced leucoindophenol from 14 parts of N-methyl-3.4.5.6-dinaphthocarbazole with a polysulfide solution of 12 parts of concentrated sodium sulphide, 14.5 parts of sulfur, 50 parts by volume of alcohol and 3 parts of copper bronze for about 50 hours to boil and works as usual on.

   The dye formed dyes cotton from liquor containing sulfur and sodium in green shades.
