Description

  

  Verfahren zur     Tierstellung    eines     indigoiden        Farbstoffes.       Es wurde gefunden, dass man einen wert  vollen,     indigoiden    Farbstoff herstellen kann,  wenn man das     ss-Thionaphtisatin,    beispiels  weise erhalten nach dem Verfahren des Pa  tentes Nr. 93486, mit     Acenaphtenon    konden  siert.

   Der Farbstoff bildet ein dunkles Pul  ver, löst sich in konzentrierter Schwefelsäure  mit braunvioletter Farbe und gibt mit     Hy-          drosulfit    und Natronlauge eine     olivegrüne          Iiüpe,    aus welcher Wolle in     licht-    und wasch  echten braunen, Baumwolle in sehr licht-,  wach- und     chlorechten,    rotbraunen Tönen       befärbt    wird.  



  <I>Beispiel:</I>       6.1    Teile     ss-Thionaphtisatin,    51 Teile       Acenaphtenon,    6 Teile Zinkchlorid werden  mit 700 Teilen Chlorbenzol längere Zeit am       R.ückflusskühler    gekocht. Nach dem Erkal  ten wird filtriert, der Rückstand wird nach-         einander    mit Alkohol, mit Natronlauge und  wieder mit Alkohol gewaschen und dann  getrocknet.



  Process for the production of an indigoid dye. It has been found that a valuable, indigoid dye can be produced if the ss-thionaphtisatin, for example obtained by the process of Patent No. 93486, is condensed with acenaphtenone.

   The dye forms a dark powder, dissolves in concentrated sulfuric acid with a brownish-violet color and, with hydrosulphite and sodium hydroxide solution, gives an olive-green shade, from which wool in light- and washable brown, cotton with very light-, wax- and chlorine-rights, red-brown tones.



  <I> Example: </I> 6.1 parts of ss-thionaphtisatin, 51 parts of acenaphtenone, 6 parts of zinc chloride are boiled with 700 parts of chlorobenzene on a reflux condenser for a long time. After cooling, it is filtered, the residue is washed successively with alcohol, with sodium hydroxide solution and again with alcohol and then dried.
