Description

  

  Verfahren zur Herstellung eines     Anthracenderivates.       Es wurde     gefunden,    dass man ein neues       Anthracenderivat,    das     2.3-Anthrachinon-          oxythionaphthen,    erhält, wenn     man    die 2.     3-          Anthrachinonthioglyli:olkarbonsäure    mit Kon  densationsmitteln behandelt.  



  Das     2.3Anthrachinonoxythionaphten     bildet ein tiefblau gefärbtes Pulver, das auf  Zusatz von Säuren nach Orange umschlägt.  Es ist mit     bräunlichgelber    Farbe in heissem       Nitrobenzol,    mit blauroter in Schwefel  säure löslich; aus letzterer Lösung wird es  durch Zusatz in Form     ora.nger    Flocken ge  fällt. Mit     Hydrosulfit    und Natronlauge wird  eine olive     Küpe    mit leuchtend blauer Blume  gebildet.  



  <I>Beispiel</I>  1 Teil     2.3-Anthra.chinonthioglykolkar-          bonsäure    wird mit 0,2 Teilen entwässertem       Natriumacetat    in 5 Teilen Essigsäure  anhydrid vorsichtig erwärmt, bis die Kohlen  säureentwicklung aufgehört hat.

   Hierauf  destilliert man das     Essigsäureanhydrid    im  Vakuum ab, giesst den Rückstand in Wasser,  kocht auf und filtriert die in gelben Flocken  ausgeschiedene     Acetylverbindung    des 2.3-         Anthrachinonoxythionaphthens.    Diese wird  dann durch Erwärmen mit Alkali in Wasser  oder Alkohol verseift, wobei die gelbe     Acetyl-          verbindung    in das     2.3-Anthrachinonoxy-          thionaphthen    übergeht.



  Process for the preparation of an anthracene derivative. It has been found that a new anthracene derivative, the 2,3-anthraquinone oxythionaphthen, is obtained if the 2,3-anthraquinone thioglylic acid is treated with condensing agents.



  2.3Anthraquinone oxythionaphthene forms a deep blue colored powder that turns orange when acids are added. It is brownish-yellow in hot nitrobenzene and soluble in sulfuric acid with blue-red; from the latter solution it is precipitated in the form of orange flakes by adding it. Using hydrosulfite and caustic soda, an olive vat with a bright blue flower is formed.



  <I> Example </I> 1 part of 2,3-anthraquinone thioglycol carboxylic acid is carefully heated with 0.2 part of dehydrated sodium acetate in 5 parts of acetic anhydride until the development of carbonic acid has ceased.

   The acetic anhydride is then distilled off in vacuo, the residue is poured into water, boiled and the acetyl compound of 2,3-anthraquinone oxythionaphthene, which has separated out in yellow flakes, is filtered off. This is then saponified by heating with alkali in water or alcohol, the yellow acetyl compound changing into 2,3-anthraquinone oxythionaphthene.
