Description

  

  Zusatzpatent zum Hauptpatent Nr. 151335.    Verfahren zur Herstellung eines neuen     Nüpenfarbstoffes.       Es wurde gefunden, dass man einen neuen       Küpenfarbstoff    erhält, wenn man das     5-Chlor-          6-methyl-3-oxytliionaphthen    mit dem     p-Di-          methylaminoanil    des     5-Chlor-7-methyl-3-oxy-          thionaphthens    kondensiert.  



  Der neue Farbstoff der Formel  
EMI0001.0009     
    stellt ein     violettrotes    Pulver dar, das sich in  konzentrierter Schwefelsäure mit grüner Farbe  löst und Baumwolle aus gelbgefärbter     Küpe     in     kräftigen,        carmosinroten    Tönen von sehr  guten     Echtheiten    färbt.  



       Beispiel:     <B>198</B> Teile     5-Chlor-6-niethyl-3-oxythionaph-          then    und 330 Teile     p-Dimethylaminoanil    des       5-Chlor-7-methyl-3-oxythionaphthens    werden  in 4000 Teilen Alkohol suspendiert und zum  Sieden erhitzt. Nach kurzem Kochen ist die    Kondensation beendet. Man filtriert, wäscht  und trocknet.



  Additional patent to main patent no. 151335. Process for the production of a new pimple 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 5-chloro-7-methyl-3-oxythionaphthene.



  The new dye in the formula
EMI0001.0009
    is a violet-red powder that dissolves in concentrated sulfuric acid with a green color and dyes cotton from a yellow-dyed vat in strong, carmosine-red shades of very good fastness properties.



       Example: 198 parts of 5-chloro-6-niethyl-3-oxythionaphthene and 330 parts of p-dimethylaminoanil of 5-chloro-7-methyl-3-oxythionaphthene are suspended in 4000 parts of alcohol and for Boiling heated. After a short boil, the condensation has ended. It is filtered, washed and dried.
