Description

  

  Verfahren zur Herstellung eines neuen     indigoiden        Farbstoffes.       Es     wurde    gefunden,     dass    man einen neuen       indgoiden    Farbstoff erhält,     wenn        man    .das       7-Chlor-2,1-thionaphthisatin        (welches    erhal  ten werden kann durch     Kondensseren    von     7-          Chlor-2-thionaphthol    mit     Ox:alylchlorid)    mit       Acenaphthenon    kondensiert.  



  Der neue Farbstoff bildet ein     .orangerotes     Pulver, löst sich in     konzentrierter    Schwefel  säure mit olivgrüner Farbe, gibt mit     Hydro-          sulfit    und Natronlauge eine gelbbraune     Küpe     und erzeugt     auf    Baumwolle Färbungen, wel  che nach dem Seifen orange und sehr echt  werden.  



  <I>Beispiel:</I>  248,5 Teile     7-Chlar-2,1-thianaphthis,a    in       arid    168 Teile     Acenaphthenon    werden in 2000  Teilen Chlorbenzol suspendiert. Nach Zu  gabe von 200 Teilen Chlorzink wird längere    Zeit zum     sch-,vachen    Sieden erhitzt. Der sich  abscheidende Farbstoff wird filtriert.



  Process for the production of a new indigoid dye. It has been found that a new indgoid dye is obtained if the 7-chloro-2,1-thionaphthisatin (which can be obtained by condensing 7-chloro-2-thionaphthol with Ox: alyl chloride) is condensed with acenaphthenone.



  The new dye forms an orange-red powder, dissolves in concentrated sulfuric acid with an olive-green color, gives a yellow-brown vat with hydrosulphite and caustic soda and creates dyes on cotton that turn orange and very fast after soaking.



  <I> Example: </I> 248.5 parts of 7-chloro-2,1-thianaphthis, a in arid 168 parts of acenaphthenone are suspended in 2000 parts of chlorobenzene. After adding 200 parts of zinc chloride, the mixture is heated to low boiling for a long time. The dye which separates out is filtered off.
