Description

  

  Verfahren zur Herstellung eines     Anthracenderivates.       Es wurde gefunden, dass man ein neues       Anthracenderivat,    die     Anthracen-        2-thio-          glykol-l-karbonsäure,    erhält, wenn man auf  die     2,1-Merkaptoanthracenkarbonsäure    eine       Monohalogenessigsäure        einwirken        lässt.    Die       Anthracen-2-thioglykol-l-karbonsäure    bildet  'ein hellgelbes Pulver, sie löst sich in Soda  lösung mit     bräunlichgelber,    in konzentrier  ter Schwefelsäure mit braunroter, bald nach  braun umschlagender Farbe.

   Die neue Ver  bindung wird zur Herstellung von Farbstof  fen verwendet.  



  <I>Beispiel:</I>  12 Teile     2,.1-Merkaptoanthracenkarbon-          säure,    70 Teile Alkohol und 5 Teile Mono  chloressigsäure werden zusammen nach Zu  gabe von 8: Teilen Kalihydrat einige Zeit  gerührt. Hierauf wird die klare Lösung  mit konzentrierter Salzsäure sauer gestellt,  von ausgeschiedenen anorganischen Salzen    und Nebenprodukten filtriert, der Alkohol  im Vakuum verdampft, der Rückstand mit       Sodalösung    extrahiert und das alkalische Ex  trakt     nusgesäuert.    .



  Process for the preparation of an anthracene derivative. It has been found that a new anthracene derivative, anthracene-2-thioglycol-1-carboxylic acid, is obtained if a monohaloacetic acid is allowed to act on the 2,1-mercaptoanthracene carboxylic acid. The anthracene-2-thioglycol-1-carboxylic acid forms a pale yellow powder, it dissolves in soda solution with a brownish-yellow, in concentrated sulfuric acid with a brownish-red color, soon turning brown.

   The new compound is used to make dyes.



  <I> Example: </I> 12 parts of 2,1-mercaptoanthracenecarboxylic acid, 70 parts of alcohol and 5 parts of monochloroacetic acid are stirred together for some time after adding 8 parts of potassium hydrate. The clear solution is then acidified with concentrated hydrochloric acid, the precipitated inorganic salts and by-products are filtered off, the alcohol is evaporated in vacuo, the residue is extracted with soda solution and the alkaline extract is acidified with a nut. .
