Description

  

  Verfahren zur Herstellung eines     Aryloxynaphtylketons.       Es wurde gefunden, dass man ein     Aryloxy-          zia.plityllieton    herstellen kann, wenn man auf       1-Oxyna.phtalin-2-carbonsäure,    mit oder ohne  Zusatz von     Verdünnungs-        bezw.        Iiondensa-          lionsmitt;eln,    aber unter Ausschluss von     Al-          kalien,        p-Clilorbenzotrichlorid    einwirken lässt.

    Die so gewonnene     1-(4'-.chlorphenyl)-heton-1-          exynaplityl    - 3 -     carbonsäure    bildet weisse     Na-          dfIn,    welche bei<B>206</B>   unter Zersetzung       schmelzen    und sich in     Ätzalkalien    und in       konzentrierter    Schwefelsäure mit gelber       Farbe    lösen.

      <I>Beispiel:</I>         23    Teile p -     Chlorbenzotrichlorid    und  18,8 Teile 1 -     Oxynaphtalin    - 2 -     carbonsäure     werden bei     Zimmertemperatur    in 100 Teile  konzentrierter Schwefelsäure eingetragen und  solange zusammen gerührt, bis sich keine Salz  säure mehr entwickelt.

   Hierauf giesst man in  Wasser, filtriert die ausgeschiedene     1-(4'-          Chlorphenyl)    -     keton    -     4-oxynaphtyl-3-carbon-          säure    ab und reinigt sie durch     T3m.kristalli-          sieren    ihres     Natriumsalzes.  



  Process for the preparation of an aryloxynaphthyl ketone. It has been found that an aryloxy zia.plityllieton can be produced if one resp. 1-Oxyna.phtalin-2-carboxylic acid, with or without the addition of diluent. Iion denaturants, but with the exclusion of alkalis, allows p-chlorobenzotrichloride to act.

    The 1- (4 '-. Chlorophenyl) -hetone-1-exynaplityl-3-carboxylic acid obtained in this way forms white needles, which melt at <B> 206 </B> with decomposition and are incorporated into caustic alkalis and concentrated sulfuric acid yellow color.

      <I> Example: </I> 23 parts of p - chlorobenzotrichloride and 18.8 parts of 1 - oxynaphthalene - 2 - carboxylic acid are added to 100 parts of concentrated sulfuric acid at room temperature and stirred together until no more hydrochloric acid develops.

   It is then poured into water, the precipitated 1- (4'-chlorophenyl) -ketone-4-oxynaphthyl-3-carboxylic acid is filtered off and it is purified by crystallizing its sodium salt.
