Description

  

  Verfahren zur Herstellung eines     Aryloxynaphtylketons.       <B>Es</B> wurde gefunden, dass man ein     Aryloxy-          n.aphtylketon    herstellen kann, wenn man auf       1-Oxynaphtalin-2-carbonsäure,    mit oder ohne  Zusatz von     Verdünnungs-        bezw.    Kondensa  tionsmitteln, aber unter Ausschluss von     Alka-          lien,        1-Chlor-2-naphthotrichlorid        einwirken     lässt.

   Die so gewonnene     1-Chlor-2-        1'-dinaph-          tylketon-4'-oxy    -     3'-carbonsäure    bildet weisse  Nadeln, die bei 213   unter Zersetzung schmel  zen und sich in     Atzalkalien    und in konzen  trierter Schwefelsäure mit gelber Farbe lösen.  <I>Beispiel:</I>  28 Teile     1-Chlor-2-naphthotrichlorid    und  <B>18,8</B> 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-          Chlor-2    .     1'-,dinaphtylketon-4'-oxy-3    -     carbon-          säure    ab und reinigt sie durch     Umkristalli-          sieren    ihres     Natriumsalzes.  



  Process for the preparation of an aryloxynaphthyl ketone. <B> It </B> has been found that an aryloxy n.aphtyl ketone can be produced if one responds to 1-oxynaphthalene-2-carboxylic acid, with or without the addition of diluent or. Condensation agents, but with the exclusion of alkali, allows 1-chloro-2-naphthotrichloride to act.

   The 1-chloro-2- 1'-dinaphthylketone-4'-oxy-3'-carboxylic acid obtained in this way forms white needles which melt at 213 with decomposition and dissolve in caustic alkalis and in concentrated sulfuric acid with a yellow color. <I> Example: </I> 28 parts of 1-chloro-2-naphthotrichloride and <B> 18.8 </B> parts of 1 - oxynaphthalene - 2 - carboxylic acid are added to 100 parts of concentrated sulfuric acid at room temperature and stirred together for as long until no more hydrochloric acid develops.

   It is then poured into water and the 1-chloro-2 which has separated out is filtered off. 1 '-, dinaphthyl ketone-4'-oxy-3 - carboxylic acid and purifies it by recrystallizing its sodium salt.
