Description

  

  Verfahren zur Herstellung eines     Aryloxynaphtylketous.       Es wurde gefunden, dass man ein     Aryloxy-          naphtyll.:eton    herstellen kann, wenn man auf  1 -     Oxynaphtalin    - 2 -     carbonsäure,    mit oder  ohne Zusatz von     Verdünnungs-        bezw.    Kon  densationsmitteln, aber unter Ausschluss von  Alkalien,     o-Chlorbenzotrichloricl    einwirken  lässt.

   Die so gewonnene     1-(2'-Chlorphenyl)-          keton    - 4 -     oxynaphtyl    - 3 -     carbonsäure    bildet  weisse Nadeln, die bei<B>213'</B> unter Zersetzung  schmelzen und sich in     Ätzalkalien    und in  konzentrierter Schwefelsäure mit gelber  Farbe löst.    <I>Beispiel:</I>    23 Teile     o-Chlorberizot.ricliloricl    und 1.8,8  Teile 1 -     Oxynaphtalin-2-carbonsäure    werden  bei Zimmertemperatur in 100 Teile konzen  trierte Schwefelsäure eingetragen und so lange  zusammen gerührt, bis sich keine Salzsäure  mehr entwickelt.

   Hierauf giesst man in Was  ser, filtriert die ausgeschiedene     1-(2'-Chlor-          phenyl)    -     keton-4-oxynaphtyl    - 3 -     ,carbonsäure     ab und reinigt sie durch     Umkristallisieren     ihres     Natriumsalzes.  



  Process for the preparation of an aryloxynaphthylketous. It has been found that an aryloxy naphtyll.:eton can be produced if one responds to 1 - oxynaphthalene - 2 - carboxylic acid, with or without the addition of diluent. Condensation agents, but with the exclusion of alkalis, allows o-chlorobenzotrichloricl to act.

   The 1- (2'-chlorophenyl) - ketone - 4 - oxynaphthyl - 3 - carboxylic acid obtained in this way forms white needles, which melt at <B> 213 '</B> with decomposition and turn into caustic alkalis and concentrated sulfuric acid with a yellow color solves. <I> Example: </I> 23 parts of o-Chlorberizot.ricliloricl and 1.8.8 parts of 1-oxynaphthalene-2-carboxylic acid are added to 100 parts of concentrated sulfuric acid at room temperature and stirred together until hydrochloric acid no longer develops .

   It is then poured into water, the precipitated 1- (2'-chlorophenyl) -ketone-4-oxynaphthyl-3 -, carboxylic acid filtered off and purified by recrystallizing its sodium salt.
