Description

  

      Yerfahreii    zur Herstellung     eines    neuen     Küpeiifarbstoffes.       Es wurde gefunden, dass man einen neuen       Küpenfarbstoff    erhält, wenn man das     6-Chlor-          4-methyl-3-oxythionaphtlien    mit dein 2-(p  Diinethylamino-)anil des     5-Chlor-4.        7-dimethyl-          3-oxythionaphthens    kondensiert.  



  Der neue     Farbstoff    der Formel  
EMI0001.0011     
    stellt ein     rosagefärbtes    Pulver dar, das sich  in konzentrierter Schwefelsäure mit grüner  Farbe löst und Baumwolle aus     rötlichgelb     gefärbter     Küpe    in kräftigen, blaustichigen       R.osatörien    von sehr guten Echtheitseigen  schaften färbt.  



  <I>Beispiel:</I>  198,5 Teile     6-Chlor-4-methyl-3-oxytliio-          naphthen    werden in 8000 Teilen Benzol mit  344 Teilen     2-(p-Dimetliylamino-)anil    des       5-Chlor-4.        7-dimethyl-3-oxythionaphthens    bei  etwa 80<B>0</B> verrührt, bis die Kondensation be-    endet ist. Der Farbstoff wird hierauf ab  filtriert, gewaschen und getrocknet.



      Yerfahreii for the production of a new Küpeii dye. It has been found that a new vat dye is obtained if the 6-chloro-4-methyl-3-oxythionaphthalene is mixed with the 2- (p-diinethylamino) anil des 5-chloro-4. 7-dimethyl-3-oxythionaphthene condensed.



  The new dye in the formula
EMI0001.0011
    is a pink-colored powder that dissolves in concentrated sulfuric acid with a green color and dyes cotton from reddish-yellow colored vats in strong, blue-tinged repositories with very good fastness properties.



  <I> Example: </I> 198.5 parts of 6-chloro-4-methyl-3-oxytliionnaphthen in 8000 parts of benzene with 344 parts of 2- (p-dimethylamino-) anil des 5-chloro-4. 7-dimethyl-3-oxythionaphthens at about 80 <B> 0 </B> stirred until the condensation has ended. The dye is then filtered off, washed and dried.
