Description

  

  Verfahren zur Herstellung eines     Arylogynaphtylketons.       Es wurde gefunden,     .dass    man ein     Aryl-          oxynaphtylketon    herstellen kann, wenn man  auf     1-Oxynaphtalin-8-sulfosäure,    mit oder  ohne Zusatz von     Verdünnungs-        bezw.    Kon  densationsmitteln, aber unter     Auss.chluss    von  Alkalien,     Benzotrichlorid    einwirken lässt.

   Die  --o gewonnene     1-Phenylketon-4-oxynaphtyl-5-          sulfosäure    bildet ein weisses Pulver, welches  sich in     Ätzalkalien    und in konzentrierter       Schwefelsäure    mit gelber Farbe löst.  



  <I>Beispiel.:</I>  <B>19,5</B> Teile     Benzotrichlorid    und 22,4 Teile       1.-Oxynaphtalin-8-sulfosäure    werden bei Zim  mertemperatur in 100 Teile konzentrierte       Sehwefelsäure    eingetragen und so lange     zu-          sarnmen    gerührt, bis sich keine Salzsäure       mehr    entwickelt. Hierauf giesst man in Was  ser, filtriert die ausgeschiedene     1-Phenyl-          l@eton-4-oxynaphtyl-5-sulfosäure    ab und rei  nigt sie durch     L        mkristallisieren    ihres Na  triumsalzes.



  Process for the preparation of an arylogynaphthyl ketone. It has been found that an aryl oxynaphthyl ketone can be produced if one responds to 1-oxynaphthalene-8-sulfonic acid, with or without the addition of diluent. Condensation agents, but with the exclusion of alkalis, allows benzotrichloride to act.

   The 1-phenylketone-4-oxynaphthyl-5-sulfonic acid obtained forms a white powder that dissolves in caustic alkalis and concentrated sulfuric acid with a yellow color.



  <I> Example: </I> <B> 19.5 </B> parts of benzotrichloride and 22.4 parts of 1-oxynaphthalene-8-sulfonic acid are added to 100 parts of concentrated sulfuric acid at room temperature and added for this period. Stirred until no more hydrochloric acid develops. It is then poured into water, the precipitated 1-phenyl-etone-4-oxynaphthyl-5-sulfonic acid is filtered off and purified by crystallizing its sodium salt.
