Description

  

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

   das sich in       Schwefelsäure    mit     grünlichblauer    Farbe löst.  Der Farbstoff färbt     Baumwolle    aus     gelber          Küpe    in echten     Totbraunen    Tönen.  



       Beispiel:     248     Teile        5-Chlor    - 1,2 -     thionaphthisatin     und 254 Teile 6 -     Thiophenoläthyläther    der       Oxythionaphthenkarb-onsäure    werden . mit  4000 Teilen Alkohol versetzt und zum Sie  den     .erwärmt.    Nachdem die Kondensation be-    endigt,     wird    der abgeschiedene Farbstoff ab  filtriert,     gewaschen    und     getrocknet.  



  Process for the production of an indigoid dye. It has been found that an indigoid dye can be produced if the 5-chloro-1,2-thionaphthisatin is condensed with the 6-thiophenol ethyl ether of oxythionaphthenecarboxylic acid. The dye sets. , dark brown powder,

   which dissolves in sulfuric acid with a greenish blue color. The dye dyes cotton from a yellow vat in real dead brown tones.



       Example: 248 parts of 5-chloro-1,2-thionaphthisatin and 254 parts of 6-thiophenol ethyl ether of oxythionaphthenecarbonic acid are used. mixed with 4,000 parts of alcohol and heated to you. After the condensation has ended, the deposited dye is filtered off, washed and dried.
