Description

  

      Zusatzpatent    zum Hauptpatent Nr. 108932.    Verfahren zur Herstellung eines neuen     Nüpenfarbstoües.       Es wurde gefunden, dass man einen neuen       Iiüpenfarbstoff    erhält, wenn man Schwefel  dichlorid (S     C1_)    auf     2,5-Di-a-naphthylamido-          benzochinon    einwirken lässt. Die Reaktion  wird zweckmässig in Gegenwart von Verdün  nungsmitteln, wie     Nitrobenzol,    gegebenen  falls in     Gegenwart    von säurebindenden Mit  teln, durchgeführt.

   Der     neue    Farbstoff bildet  rin dunkelblaues Pulver, das sich in     konzen-          t        rierter    Schwefelsäure mit     blaugrüner    Farbe  löst und Wolle aus der     Hydrosulfitküp,e    in       violettgra,uen    Nuancen     färbt.       <I>Beispiel:

  </I>    150 Teile trockenes     Nitrobenzol    und 9,8  Teile 2,5 -     Di    - a -     naphthylamidobenzochinon     werden unter gutem Rühren auf     -f-    5   ab-    gekühlt und im Laufe einer Stunde mit<B>2,6</B>  Teilen     Schwefel@dichlorid    (S     C12)    versetzt.  Nach längerem Rühren wird filtriert. gewa  schen und getrocknet.



      Additional patent to the main patent no. 108932. Process for the production of a new nub dye. It has been found that a new pulp dye is obtained if sulfur dichloride (S C1_) is allowed to act on 2,5-di-a-naphthylamido-benzoquinone. The reaction is conveniently carried out in the presence of diluents such as nitrobenzene, if necessary in the presence of acid-binding agents.

   The new dye forms a dark blue powder which dissolves in concentrated sulfuric acid with a blue-green color and dyes wool from the hydrosulfite pot in shades of purple-gray. <I> example:

  150 parts of dry nitrobenzene and 9.8 parts of 2,5-di-a-naphthylamidobenzoquinone are cooled to -f- 5 with thorough stirring and are reduced to 2.6 over the course of an hour Share sulfur @ dichloride (S C12) added. After prolonged stirring, it is filtered. washed and dried.
