Description

  

  Verfahren zur     Herstellung    eines     neuen        Nüpenfarbst ffes.       Es wurde gefunden, dass man einen neuen       Küpenfarbstoff    erhält, wenn man das     2-(p-          Dimethylamino-)anil    des     5-Chlor-4.        7-dimethyl-          3-oxythionaphtens    mit     1-Chlor-2.        3-naphtthio-          indoxyl    kondensiert.  



  Der neue     Farbstoff    der Formel  
EMI0001.0014     
    stellt ein rotviolettes Pulver dar, das sich in  konzentrierter Schwefelsäure mit grüner Farbe  löst und Baumwolle aus     oraugebraun    ge  färbter     Küpe    in blauvioletten Tönen von  sehr guten     Echtheiten    färbt.  



  <I>Beispiel:</I>  344 Teile     2-(p-Dimethylamirro-)anil    des       5-Chlor-4.7-dirnethyl-3-oxythionaphtens    wer  den mit 234,5 Teilen     1-Chlor-2.        3-naphtthio-          indoxyl    in 8000 Teilen Benzol zum Sieden  erhitzt. Nach beendeter Kondensation wird    der     Farbstoff        abfiltriert,    gewaschen und ge  trocknet.



  Process for the production of a new pomple color. It has been found that a new vat dye is obtained if the 2- (p-dimethylamino) anil des 5-chloro-4. 7-dimethyl-3-oxythionaphthene with 1-chloro-2. 3-naphthioindoxyl condensed.



  The new dye in the formula
EMI0001.0014
    represents a red-violet powder that dissolves in concentrated sulfuric acid with a green color and dyes cotton from orange-brown vat in blue-violet shades of very good fastness properties.



  <I> Example: </I> 344 parts of 2- (p-dimethylamirro-) anil des 5-chloro-4,7-dirnethyl-3-oxythionaphthene with 234.5 parts of 1-chloro-2. 3-naphthioindoxyl in 8000 parts of benzene heated to boiling. When the condensation has ended, the dye is filtered off, washed and dried.
