Description

  

  Verfahren zur Herstellung eines neuen     Nüpenfarbstoffes.       Es wurde gefunden, dass man einen neuen       Küpenfarbstoff    erhält, wenn man das     5-Chloi#-          4.7-dimethyl-3-oxythionaphthen    mit dem       2-(p-Diinetliylarnino-)anil    des     4.7-Dimethyl-          3-oxytliionaplithens        kondensiert.     



  Der neue     Farbstoff    der Formel  
EMI0001.0010     
    stellt ein blaustichig     rosagefärbtes    Pulver  dar, das sich in konzentrierter Schwefelsäure  mit grüner Farbe löst und .Baumwolle aus       blassgelb    gefärbter     Küpe    in kräftigen, blau  stichigem     Rosatönen    von sehr guten Echt  heitseigenschaften färbt.  



       Beispiel:          '212,5    Teile     5-Chlor-4.7-dimethyl-3-oxy-          thionaplithen    werden in 8800 Teilen Benzol  mit<B>309,5</B> Teilen     2-(p-Dimethylamino-)anil     des     4.7-Dimetliyl-3-oxythioriaphtheris    bei  etwa<B>800</B> verrührt, bis die Kondensation    beendet ist. Der Farbstoff wird hierauf ab  filtriert, gewaschen und getrocknet.



  Process for the production of a new pebble dye. It has been found that a new vat dye is obtained if the 5-chloi # - 4.7-dimethyl-3-oxythionaphthene is condensed with the 2- (p-diinetliylamino) anil of the 4,7-dimethyl-3-oxytliionaplithene.



  The new dye in the formula
EMI0001.0010
    is a blue-tinged pink powder that dissolves in concentrated sulfuric acid with a green color and dyes cotton from a pale yellow vat in strong, blue-tinged pink tones with very good fastness properties.



       Example: 212.5 parts of 5-chloro-4,7-dimethyl-3-oxythionaplithen are mixed with 8,800 parts of benzene with 309.5 parts of 2- (p-dimethylamino) anil of 4,7-dimethyl -3-oxythioriaphtheris stirred at about <B> 800 </B> until the condensation has ended. The dye is then filtered off, washed and dried.
