Description

  

  Verfahren zur Herstellung eines neuen     Küpenfarbstoffes.       Es     wurde    gefunden,     dass    man einen neuen       Küpenfarbstoff    erhält, wenn man     Thionyl-          chlorid        (SOC12)    auf 2. 5 -     Dianilidobenzo-          chinon    einwirken lässt. Die Reaktion wird  zweckmässig in Gegenwart von Verdünnungs  mitteln, wie Nitrobenzol, gegebenenfalls in  Gegenwart von säurebindenden Mitteln,  durchgeführt.

   Der neue Farbstoff bildet ein  braunes Pulver, das sich in konzentrierter       Schwefelsäure    mit violetter Farbe löst und  Wolle aus der     Hy        dTosulfitküpe    in vollen  echten braunen Nuancen färbt.         Beispiel:       7,2 Teile 2.     5-Dianiliclobenzo@chinon    wer  den in     1.1-t    Teilen     Nitrobenzol    kalt mit 9  Teilen     Thionylchlorid    versetzt, nach und  nach auf 100 bis 120' erhitzt und drei Stun  den gerührt. Nach dem     Erkalten    wird fil  triert und .gewaschen.

   Der so erhaltene Farb-         stoff    besitzt die in der Einleitung beschrie  benen     Eigenschaften.     



  Ein sehr ähnliches Produkt erzielt man  bei längerem Kochen der Reaktionsmasse.  Man kann auch unter Zusatz eines säurebin  denden Mittels arbeiten.



  Process for the production of a new vat dye. It has been found that a new vat dye is obtained if thionyl chloride (SOC12) is allowed to act on 2.5 - dianilidobenzoquinone. The reaction is conveniently carried out in the presence of diluents, such as nitrobenzene, if appropriate in the presence of acid-binding agents.

   The new dye forms a brown powder that dissolves in concentrated sulfuric acid with a purple color and dyes wool from the hy dtosulfite vat in full, genuine brown shades. Example: 7.2 parts of 2. 5-Dianiliclobenzo @ quinone who added 9 parts of thionyl chloride in 1.1 t parts of cold nitrobenzene, gradually heated to 100 to 120 'and stirred for three hours. After cooling, it is filtered and washed.

   The dye obtained in this way has the properties described in the introduction.



  A very similar product is obtained by boiling the reaction mass for a long time. You can also work with the addition of an acid-binding agent.
