Description

  

  Verfahren zur     Ifferstellung    eines neuen     Küpenfarbstoffes.       Es -wurde gefunden,     dass    man einen neuen       Küpenfarbstoff    erhält, wenn man das     p-Di-          methylaminoanil    des     5-Methyl-6-chlorthio-          indoxyls    mit     1-Chlor-2,3-naphththioindoxyl     kondensiert.  



  Der neue Farbstoff der Formel  
EMI0001.0010     
    stellt ein     violettblaues    Pulver dar, das sich  in konzentrierter Schwefelsäure mit grüner  Farbe löst. Er gibt mit     Hydrosulfit    und  Natronlauge eine gelbgefärbte     Küpe,    aus der  Baumwolle in sehr echten violetten Tönen  gefärbt wird.  



  <I>Beispiel:</I>  <B>330</B> Teile     p-Dimethylaininoanil    des     5-          Methyl-6-chloi,thioindoxyls    und<B>235</B> Teile       1-Ohlor-2,3-naphththioindoxyl    werden in  12,000 Teilen Benzol suspendiert und wäh  rend einiger Stunden unter Rühren und     Rück-          flusskühlung    zum Sieden erhitzt. Hierauf wird    von ausgeschiedenem Farbstoff filtriert, mit  Benzol gewaschen und getrocknet.



  Process for producing a new vat dye. It has been found that a new vat dye is obtained when the p-dimethylaminoanil of 5-methyl-6-chlorothioindoxyl is condensed with 1-chloro-2,3-naphthioindoxyl.



  The new dye in the formula
EMI0001.0010
    is a purple-blue powder that dissolves in concentrated sulfuric acid with a green color. With hydrosulfite and caustic soda, he gives a yellow-dyed vat from which cotton is dyed in very real purple tones.



  <I> Example: </I> <B> 330 </B> parts of p-dimethylaininoanil des 5-methyl-6-chloi, thioindoxyl and <B> 235 </B> parts of 1-chloro-2,3-naphthioindoxyl are suspended in 12,000 parts of benzene and heated to boiling for a few hours with stirring and reflux cooling. The dye which has separated out is then filtered off, washed with benzene and dried.
