Description

  

  Verfahren zur Herstellung eines neuen     Küpenfarbstofes.       Es wurde gefunden, dass man einen neuen       Küpenfarbstoff    erhält, wenn man das     5-Chlor-          6        -methyl-    3     -oxythionaphthen    mit dem p -     Di-          methylaminoanil    des     4-1Vlethyl-6-chlor-3-oxy-          thionaphthens    kondensiert.  



  Der neue     Farbstoff    der Formel  
EMI0001.0012     
    stellt ein     violettstichig    rotes Pulver dar, das  sich in konzentrierter Schwefelsäure mit grüner  Farbe löst und Baumwolle aus gelb gefärbter       Küpe    in     violettstichigen        Rosatönen    von guter  Echtheit färbt.  



  <I>Beispiel:</I>  198 Teile     5-Chlor-6-methyl-3-oxythio-          naphthen    und 330 Teile     p-Dimethylaminoanil     des     4-Methyl-6-chlor-3-oxythionaphthens    wer  den in 4000 Teilen Alkohol suspendiert und  zum Sieden erhitzt. Nach kurzem Kochen ist    die Kondensation beendet. Man filtriert, wäscht  und trocknet.



  Process for the production of a new vat dye. It has been found that a new vat dye is obtained if the 5-chloro-6-methyl-3-oxythionaphthene is condensed with the p-dimethylaminoanil of 4-1Vlethyl-6-chloro-3-oxythionaphthene.



  The new dye in the formula
EMI0001.0012
    is a violet-tinged red powder that dissolves in concentrated sulfuric acid with a green color and dyes cotton from a yellow-dyed vat in violet-tinged pink shades of good fastness.



  <I> Example: </I> 198 parts of 5-chloro-6-methyl-3-oxythionaphthene and 330 parts of p-dimethylaminoanil of 4-methyl-6-chloro-3-oxythionaphthene who are suspended in 4000 parts of alcohol and heated to boiling. After a short boil, the condensation has ended. It is filtered, washed and dried.
