Description

  

      Zusatzpatent    zum Hauptpatent Nr. 163279-    Verfahren     zur    Herstellung eines neuen     Nüpenfarbstoffes.       Es wurde gefunden, dass man einen neuen       Küpenfarbstoff    erhält, wenn man     7-Chlor-          4.6-dirnethyl-3-oxythionaphtherr    mit dem       2-(p-Dirnethylamino-)anil    des     6-Ätlroxy-3-oxy-          thionaphthens    kondensiert.  



  Der neue Farbstoff der Formel  
EMI0001.0010     
    stellt ein scharlachrotes Pulver dar, das sich  in konzentrierter Schwefelsäure mit grüner  Farbe löst und Baumwolle aus gelbgefärbter       Küpe    in hervorragend echten Scharlachtönen  färbt.  



  <I>Beispiel:</I>  212,5 Teile     7-Chlor-4.6-dimetbyl-3-oxy-          thionaphthen    und 326 Teile     2-(p-Dimethyl-          amino-)anil    des     6-Äthoxy-3-o3..-thiorraphtberrs     werden in 4000 Teilen Alkohol zum Sieden    erhitzt, bis die Kondensation beendet ist.  Hierauf wird filtriert und getrocknet.



      Additional patent to the main patent no. 163279- Process for the production of a new pimple dye. It has been found that a new vat dye is obtained if 7-chloro-4,6-dirnethyl-3-oxythionaphthene is condensed with 2- (p-dirnethylamino) anil of 6-ethoxy-3-oxythionaphthens.



  The new dye in the formula
EMI0001.0010
    is a scarlet powder that dissolves in concentrated sulfuric acid with a green color and dyes cotton from a yellow-dyed vat in brilliantly real scarlet tones.



  <I> Example: </I> 212.5 parts of 7-chloro-4,6-dimetbyl-3-oxythionaphthene and 326 parts of 2- (p-dimethylamino) anil des 6-ethoxy-3-o3 .. -thiorraphtberrs are heated to boiling in 4000 parts of alcohol until the condensation has ended. It is then filtered and dried.
