Description

  

      Zusatzpatent    zum     Hauptpatent    Nr. 151335.    Verfahren zur Herstellung eines neuen     güpenfarbstoi%s.       Es wurde gefunden, dass man einen neuen       Küpenfarbstoff    erhält, wenn man     5,6-Dichlor-          3-oxythionaphthen    mit dem     p-Diinethylamino-          anil    des     2,3-Naphtthioindoxyls    kondensiert.  Der neue Farbstoff der Formel  
EMI0001.0010     
    stellt ein grauviolettes Pulver dar, das sich  in konzentrierter Schwefelsäure mit grüner  Farbe löst.

   Er gibt mit     Hydrosulfit    und  Natronlauge eine orange gefärbte     Küpe,    aus  der Baumwolle in sehr echten dunkelvioletten  Tönen gefärbt wird.  



  <I>Beispiel:</I>  218 Teile     5,6-Dichlor-3-oxythionaphthen     und 332 Teile     p-Diinethylamirroanil    des     2,3-          Naphtthioindoxyls    werden in 4000 Teilen  Alkohol zum Sieden erhitzt, bis die Konden-         sation    zum Farbstoff beendet ist. Man filtriert  und trocknet.



      Additional patent to main patent No. 151335. Process for the production of a new güpenfarbstoi% s. It has been found that a new vat dye is obtained if 5,6-dichloro-3-oxythionaphthene is condensed with the p-diinethylaminoanil of 2,3-naphthioindoxyl. The new dye in the formula
EMI0001.0010
    is a gray-violet powder that dissolves in concentrated sulfuric acid with a green color.

   He gives an orange colored vat with hydrosulphite and caustic soda, from which cotton is dyed in very real dark purple tones.



  <I> Example: </I> 218 parts of 5,6-dichloro-3-oxythionaphthene and 332 parts of p-diinethylamirroanil of 2,3-naphthioindoxyl are heated to the boil in 4000 parts of alcohol until the condensation to the dye has ended . Filter and dry.
