Description

  

  Verfahren zur Herstellung eines neuen     Küpenfarbstoffes.       Es wurde gefunden, dass man einen neuen       Küpenfarbstoff    erhält, wenn man     4.7-Di-          chlor-6-methyl-3-oxythionaphthen    mit dem       2-(p-Dimethylamino-)anildes        4-Methyl-6-chlor-          3-oxythionaphthens    kondensiert.  



  Der neue     Farbstoff    der Formel:  
EMI0001.0009     
    stellt ein rotes Pulver dar, das sich in kon  zentrierter     Schwefelsäure    mit grüner Farbe  löst und Baumwolle aus gelbgefärbter     Küpe     in hervorragend echten, reinen     Rosatönen     färbt.

      <I>Beispiel:</I>    233 Teile     4.7-Dichlor-6-methyl-3-oxythio-          "Itlzthen    und 330,5 Teile     2-(p-Dimethyl-          ämix < o-)anil    des     4-Methyl-6-ciilor-3-oxythio-          naphthens        werden    mit 4000     Volumteilen    Eis  essig     auf        dem    Wasserbade erhitzt, bis die    Kondensation beendigt ist. Dann wird fil  triert, gewaschen und getrocknet.



  Process for the production of a new vat dye. It has been found that a new vat dye is obtained if 4,7-dichloro-6-methyl-3-oxythionaphthene is condensed with 2- (p-dimethylamino) anildes 4-methyl-6-chloro-3-oxythionaphthene.



  The new dye of the formula:
EMI0001.0009
    is a red powder that dissolves in concentrated sulfuric acid with a green color and dyes cotton from a yellow-dyed vat in extremely genuine, pure pink tones.

      <I> Example: </I> 233 parts of 4.7-dichloro-6-methyl-3-oxythio- "Itlzthen and 330.5 parts of 2- (p-dimethyl- ämix <o-) anil des 4-methyl-6- ciilor-3-oxythionaphthens are heated on a water bath with 4000 parts by volume of glacial acetic acid until the condensation has ended, then filtered, washed and dried.
