Description

  

  Verfahren zur Herstellung eines     indigolden        Farbstoffes.       Es wurde gefunden,     dass    man einen wert  vollen,     indigoiden    Farbstoff herstellen kann,  wenn man das     fl-Thionaphtisatin,    beispiels  weise erhalten nach dem Verfahren des Pa  tentes     Nr.   <B>93486,</B> mit     Oxythionaphien    kon  densiert.

   Der Farbstoff bildet ein dunkles  Pulver, löst sich in konzentrierter Schwefel  säure mit     dunkelblaugruner    Farbe und gibt  mit     Hydrosulfit    und     Natronlauge    eine gelbe       Küpe,    aus welcher Wolle in licht- und wasch  echten roten, Baumwolle in sehr licht-,     wasch-          und    -chlorechten,     bord-eaux    Tönen gefärbt  wird.  



  <I>Beispiel:</I>  In<B>7000</B> Teilen Alkohol werden 214 Teile       P-Thionaphtisatin    und<B>150</B> Teile     Oxythio-          naphten    eingetragen und hierauf einige Stun  den am     Rüekflusskühler    gekocht. Die     Kou-          densation        kann,durch.    Zusatz von Ammoniak  oder     Dimethylanilin    beschleunigt werden.  Nachdem sie, beendet ist, wird filtriert, ge  waschen -und getrocknet,    Die gleiche Reaktion findet auch statt,  wenn die Komponenten zusammen in Chlor  benzol, zweckmässig in Gegenwart eines Kon  densationsmittels, wie Chlorzink, erwärmt  werden, oder mit Schwefelsäure und Eisessig  behandelt werden.



  Process for the production of an indigolden dye. It has been found that a valuable, indigoid dye can be produced if the fl-thionaphtisatin, for example obtained by the process of patent no. 93486, is condensed with oxythionaphies.

   The dye forms a dark powder, dissolves in concentrated sulfuric acid with a dark blue-green color and, with hydrosulphite and caustic soda, gives a yellow vat from which wool in light and washable red, cotton with very light, wash and chlorine rights, border -Dyed in white tones.



  <I> Example: </I> In <B> 7000 </B> parts of alcohol, 214 parts of P-thionaphthisatin and <B> 150 </B> parts of oxythionaphthene are added and then boiled for a few hours on the reflux condenser. The condensation can, through. Addition of ammonia or dimethylaniline can be accelerated. After it has ended, it is filtered, washed and dried. The same reaction also takes place when the components are heated together in chlorobenzene, advantageously in the presence of a condensation agent such as zinc chloride, or are treated with sulfuric acid and glacial acetic acid .
