Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 163280.         Verfahren    zur Herstellung eines neuen     Küpenfarbstoffes.       Es wurde gefunden, dass man einen neuen       Küpenfarbstoff    erhält, wenn man das     5-Clilor-          4.7-diirietbyl-3-oxythionaphtlieri    mit dem       2-(p-Dimethylaniino-)anil    des     6-Äthoxy-3-oxy-          thionaplithens    kondensiert.  



  Der neue Farbstoff der Formel  
EMI0001.0009     
    stellt ein gelbrotes Pulver dar, das sich in  konzentrierter Schwefelsäure mit grasgrüner  Farbe löst und Baumwolle aus grüngelb ge  färbter     Küpe    in     Rosatönen    von sehr guter  Echtheit färbt.  



  <I>Beispiel:</I>  212,5 Teile     5-Chlor-4.7-dimethyl-3-oxy-          thionaphthen    und 326 Teile     2-(p-Dimethyl-          amino-)anil    des     6-Äthoxy-3-oxythionaphthens          werden    in 8000 Teilen Benzol     zum-Sieden     erhitzt, bis die Kondensation beendet ist.    Der Farbstoff wird filtriert, gewaschen und  getrocknet.



  <B> Additional patent </B> to main patent no. 163280. Process for the production of a new vat dye. It has been found that a new vat dye is obtained if the 5-Clilor-4,7-diirietbyl-3-oxythionaphthalene is condensed with the 2- (p-dimethylaniino) anil of the 6-ethoxy-3-oxythionaplithene.



  The new dye in the formula
EMI0001.0009
    is a yellow-red powder that dissolves in concentrated sulfuric acid with a grass-green color and dyes cotton from a green-yellow vat in pink shades of very good fastness.



  <I> Example: </I> 212.5 parts of 5-chloro-4,7-dimethyl-3-oxythionaphthene and 326 parts of 2- (p-dimethylamino-) anil of 6-ethoxy-3-oxythionaphthene are used in 8000 parts of benzene are heated to boiling until the condensation has ended. The dye is filtered, washed and dried.
