Description

  

  Verfahren zur Herstellung eines neuen     Nüpenfarbstoffes.       Es wunde gefunden, dass man einen neuen       Küpenfarbstoff    erhält, wenn man Schwefel  ehlorür auf     2,5-Di.-p-oxyanilidobenzochinon    bei  niedrigen     Temperaturen        einwirken    lässt. Die  Reaktion wird zweckmässig in Gegenwart.  von Verdünnungsmitteln, wie Nitrobenzol,  gegebenenfalls in     Gegenwart    von säurebin  denden     Mitteln,    durchgeführt.

   Der neue  Farbstoff bildet ein     rötlichbraunes    Pulver,  das     sich    in     konzentrierter    Schwefelsäure mit  blauer Farbe löst und Wolle aus :der     Hydro-          sulfitküpe    in echten gelben Nuancen färbt.       Beispiel:     8 Teile     2,5-Di-p-oxyanvlid:obenzocMnon,          suspendiert        in    120 Teilen Nitrobenzol, wer  den bei 2 bis- 6   unter gutem Rühren mit         10,1        Teilen        Sehwefelehlorür        (SZCl2)    versetzt.

    Nach     längerem.    Rühren wird filtriert, ge  waschen und ,getrocknet.



  Process for the production of a new pebble dye. It was found that a new vat dye is obtained if sulfur chloride is allowed to act on 2,5-di.-p-oxyanilidobenzoquinone at low temperatures. The reaction is conveniently carried out in the presence. of diluents such as nitrobenzene, optionally in the presence of acid-binding agents carried out.

   The new dye forms a reddish-brown powder that dissolves in concentrated sulfuric acid with a blue color and turns wool: the hydrosulfite vat dyes real yellow nuances. Example: 8 parts of 2,5-di-p-oxyanvlid: obenzocMnon, suspended in 120 parts of nitrobenzene, who added 10.1 parts of sulfuric acid (SZCl2) at 2 to 6 with thorough stirring.

    After a long time. Stirring is filtered, washed and dried.
