Description

  

      Verfahren    zur Herstellung eines neuen     indigoiden        Farbstoffes.       Es wurde gefunden, dass man einen neuen       indigoiden        Farbstoff    erhält, wenn man das       5-Chlor-2    .     1-thionaphthisatin,    welches durch  Kondensieren von     5-Chlor-2-thionaphthol    mit       Oxalylchlorid    erhalten werden kann, mit     Ace-          naphthenon    kondensiert.  



  Der neue Farbstoff stellt ein braunes Pul  ver dar und löst sich in     konz.    Schwefelsäure  mit blauer Farbe. Er bildet eine gelbbraune       Küpe    und färbt Baumwolle sehr echt in reinen  braunen Nuancen.  



  <I>Beispiel:</I>  248,5 Teile     5-Chlor-2    .     1-thionaphthisatin,     168 Teile     Acenaphthenon    und 200 Teile Zink  chlorid werden in 2000 Teilen Chlorbenzol  mehrere Stunden rückfliessend gekocht. Nach    dem Erkalten wird filtriert; der ausgeschie  dene Farbstoff mit Alkohol gewaschen und  getrocknet.



      Process for the production of a new indigoid dye. It has been found that a new indigoid dye is obtained if the 5-chloro-2. 1-thionaphthisatin, which can be obtained by condensing 5-chloro-2-thionaphthol with oxalyl chloride, condensed with acenaphthenone.



  The new dye is a brown powder and dissolves in conc. Sulfuric acid of blue color. It forms a yellow-brown vat and dyes cotton very realistically in pure brown shades.



  <I> Example: </I> 248.5 parts of 5-chloro-2. 1-thionaphthisatin, 168 parts of acenaphthenone and 200 parts of zinc chloride are refluxed for several hours in 2000 parts of chlorobenzene. After cooling, it is filtered; the excreted dye washed with alcohol and dried.
