Description

  

      Terfahren    zur Herstellung eines neuen     indigoiden        Farbstoffes.       Es wurde gefunden, dass man einen neuen       indigoiden        Farbstoff    erhält, wenn das     1-Chlor-          2#3-thionaphthisatin,    welches durch Konden  sieren von     1-Chlor-2-thionaphthol    mit     Oxalyl-          chlorid    erhalten werden kann, mit     6-Chlor-          oxythionaplitenkarbonsäure    kondensiert.  



  Der neue     Farbstoff    bildet ein     violettrotes     Pulver, löst sich in     konz.    Schwefelsäure mit       olivegrüner    Farbe und gibt mit     Hydrosulfit     und Natronlauge eine     bräunlich-gelbe        Küpe,     aus welcher Baumwolle in violetten Tönen  gefärbt wird, die beim Seifen etwas röter  und sehr echt werden.

           getragen        und        hierauf        längere        Zeit        am          Beispiel     In 10000 Teile Alkohol werden 248,5  Teile     1-Chlor-2#3-thionaphthisatin    und<B>228,5</B>  Teile     6-Chloroxy        thionaphtenkarbonsiture    ein-    gekocht. Der gebildete Farbstoff  wird filtriert, gewaschen und getrocknet.



      Technique for the production of a new indigoid dye. It has been found that a new indigoid dye is obtained if 1-chloro-2 # 3-thionaphthisatin, which can be obtained by condensing 1-chloro-2-thionaphthol with oxalyl chloride, with 6-chlorooxythionaplitic acid condensed.



  The new dye forms a purple-red powder, dissolves in conc. Sulfuric acid with an olive-green color and, with hydrosulfite and sodium hydroxide solution, gives a brownish-yellow vat, from which cotton is dyed in violet tones, which become a little redder and very real when soapy.

           and then for a long time using the example. 248.5 parts of 1-chloro-2 # 3-thionaphthisatin and 228.5 parts of 6-chlorooxy thionaphthene carbonate are boiled down in 10,000 parts of alcohol. The dye formed is filtered, washed and dried.
