Description

  

      Verfahren    zur Herstellung eines     indigoiden    Farbstoffes.    Es     wurde    gefunden, dass     man    einen     indi-          goiden    Farbstoff herstellen kann, wenn man  das     5-Brom-2,1-thionaphthisatin    mit dem     6-          Thiophenoläthyläther    der     Oxythionaphthen-          karbonsäure        kondensiert.    Der Farbstoff stellt  ein dunkelbraunes Pulver dar, das sich     in     Schwefelsäure mit blauer Farbe löst.

   Der  Farbstoff bildet eine     bräunlichgelbe        Tiüpe     und färbt Baumwolle in echten     rotbraunen     Tönen.  



       Beispiel:     293 Teile     5-Brom    - 2,1 -     thionaphthisatin     und 254 Teile     6-Thiophenoläthyläther    der       Oxythionaphthenkarbonsäure    werden mit  4000 Teilen Alkohol versetzt und zum Sie  den erhitzt. Nach kurzer Zeit ist die     Kon-          densatio:n    beendigt. Der abgeschiedene Farb-         stoff    wird     abfiltriert,        ge-vias,chen    und ge  trocknet.



      Process for the production of an indigoid dye. It has been found that an indigoid dye can be produced if the 5-bromo-2,1-thionaphthisatin is condensed with the 6-thiophenol ethyl ether of oxythionaphthene carboxylic acid. The dye is a dark brown powder that dissolves in sulfuric acid with a blue color.

   The dye forms a brownish-yellow veil and dyes cotton in real red-brown tones.



       Example: 293 parts of 5-bromine-2,1-thionaphthisatin and 254 parts of 6-thiophenol ethyl ether of oxythionaphthenecarboxylic acid are mixed with 4000 parts of alcohol and heated to you. After a short time, the condensation: n is over. The deposited dye is filtered off, vias, washed and dried.
