  verfahren zur Herstellung eines     Aryloxynaphtylketons.       Es wurde gefunden, dass man ein     Aryloxy-          na.plity        llzeton    herstellen kann, wenn man auf       ss-Naplithol,    mit oder ohne Zusatz von     Ver-          dünnunl;s-        bezw.        Kondensationsmitteln,    aber  unter Ausschluss von     Alkalien,        Belizotriehlo-          rid        einwirken    lässt.

   Das so gewonnene 1 .     1'-          PhenyInaplity    1 - 2'-     oxy    -     keton    bildet weisse  Nadeln,     !die    bei 175   schmelzen und sich in       Ätzalkalien    und in konzentrierter Schwefel  säure mit gelber Farbe lösen.         Beispiel:            19,,i.    Teile     Benzotrichlorid    und 14,4 Teile       ss-Nalilitliol    werden unter Kühlung in 100  Teile konzentrierte Schwefelsäure eingetra  gen und so lange zusammen gerührt, bis sich  keine Salzsäure mehr entwickelt.

   Hierauf  giesst man in Wasser, filtriert das ausge  schiedene 1 .     l.'-Plienylnaphtyl    -     2'-oxy-keton     ab und .reinigt es durch     Umkristallisieren     seines     Natriumsalzes.  



  process for the production of an aryloxynaphthyl ketone. It has been found that an aryloxyna.plity llteton can be produced by using ss-naplithol, with or without the addition of thinner or thinner. Condensation agents, but with the exclusion of alkalis, allows belizotri chloride to act.

   The 1. 1'- PhenyInaplity 1 - 2'- oxy - ketone forms white needles! Which melt at 175 and dissolve in caustic alkalis and in concentrated sulfuric acid with a yellow color. Example: 19,, i. Parts of benzotrichloride and 14.4 parts of ß-nalilitliol are introduced into 100 parts of concentrated sulfuric acid with cooling and stirred together until hydrochloric acid no longer develops.

   It is then poured into water, the precipitated 1 is filtered off. l'-Plienylnaphtyl - 2'-oxy-ketone and purifies it by recrystallizing its sodium salt.
