      Zusaft,patent        zuin    Hauptpatent     Nr.   <B>108932.</B>    Verfahren zur     Herstellugg    eines neuen     Küpenfarbstoffes.       Es wurde gefunden,     dass    man einen neuen       Küpenfarbstoff    erhält, wenn man     Thionyl-          chlorid    auf     2,5-Di-#inilido-6-ch,lo.rbeilzochlilon     einwirken     lässt.    Die Reaktion wird zweck  mässig in Gegenwart von Verdünnungsmit  teln, wie     Nitrobenzol,

      gegebenenfalls in     Ge-          --enwart    von säurebindenden Mitteln, durch  geführt. Der neue Farbstoff bildet ein       rötlichbraunes,    kristallinisches Pulver, das  sich in konzentrierter Schwefelsäure mit  violetter Farbe löst und Wolle aus der     Hy-          drosulfitküpe    in vollen echten     rotbraunen     Nuancen färbt.

      Zusaft, patent for main patent no. <B> 108932. </B> Process for the production of a new vat dye. It has been found that a new vat dye is obtained if thionyl chloride is allowed to act on 2,5-di- # inilido-6-ch, lo.rbeilzochlilon. The reaction is expediently in the presence of diluents such as nitrobenzene,

      possibly in the presence of acid binding agents. The new dye forms a reddish-brown, crystalline powder that dissolves in concentrated sulfuric acid with a violet color and dyes wool from the hydrosulfite vat in full, genuine red-brown shades.



  <I> Example: </I> <B> 8 </B> parts of 2,5-diaiiilido-6-c, # ll # lorbeiizoehinoii are mixed in <B> 160 </B> parts of nitrobenzene cold with <B> 9 , 2 parts of thionyl chloride are added, the mixture is gradually heated to between 100 and 120 and stirred for three hours at this temperature is filtered, washed and (re-dried.
