Description

  

  Verfahren zur Herstellung eines neuen     Iiüpenfarbstoffes.       Es wurde gefunden, dass man einen neuen       Küpenfarbstoff    erhält, wenn man     7-Chlor-          4.6-dimethyl-3-oxythionaphthen    mit dem       2-(p-Dimethylamino-)anil    des     1-Chlor-2.3-          naphthoxythiophens    kondensiert.  



  Der neue Farbstoff der Formel  
EMI0001.0008     
    stellt ein violettes Pulver dar, das sich in  konzentrierter Schwefelsäure mit grüner Farbe  löst und Baumwolle aus     orangebrauner        Küpe     in hervorragend echten, violetten Tönen färbt.  <I>Beispiel:</I>  212,5 Teile     7-Chlor-4        .6-dimethyl-3-oxy-          thionapbthen    und 366,5 Teile     2-(p-Dimethyl-          amino-)anil    des     1-Chlor-2.3-naphtboxythio-          phens    werden mit 4000     Volurnteilen    Eisessig  auf dem Wasserbade erhitzt, bis die Kon-         densation    beendigt ist.

   Dann wird filtriert,  gewaschen und getrocknet.



  Process for the preparation of a new pulp dye. It has been found that a new vat dye is obtained if 7-chloro-4,6-dimethyl-3-oxythionaphthene is condensed with the 2- (p-dimethylamino) anil of 1-chloro-2,3-naphthoxythiophene.



  The new dye in the formula
EMI0001.0008
    is a purple powder that dissolves in concentrated sulfuric acid with a green color and dyes cotton from an orange-brown vat in brilliantly real, purple tones. <I> Example: </I> 212.5 parts of 7-chloro-4 .6-dimethyl-3-oxy-thionapthene and 366.5 parts of 2- (p-dimethylamino) anil des 1-chloro-2.3 -naphtboxythiophens are heated with 4000 parts by volume of glacial acetic acid on the water bath until the condensation has ended.

   It is then filtered, washed and dried.
