Description

  

      Verfahren    zur Herstellung eines     Aryloxynaphtylketous.       Es wurde gefunden, dass man ein     Aryl-          oxynaphtylketon    herstellen kann, wenn man  auf     2-Oxynaphtalin-6-sulfosäure,    mit oder  ohne Zusatz von     Verdünnungs-        bezw.    Kon  densationsmitteln, aber unter Ausschluss von  Alkalien,     Benzotrichlorid    einwirken lässt. Die  so gewonnene     1-Phenylketon-2-oxynaphtalin-          6-sulfosäure    bildet ein weisses Pulver, welches  sich in     Atzalkalien    und in konzentrierter  Schwefelsäure mit gelber Farbe löst.

      <I>Beispiel:</I>    19,5 Teile     Benzotrichlorid    und 22,4 Teile       2-Oxynaphtalin-6-sulfosäure        werden    bei Zim  mertemperatur in 100 Teile konzentrierte  Schwefelsäure eingetragen und so lange zu  sammen gerührt, bis sich keine Salzsäure  mehr entwickelt. Hierauf giesst man in Was  ser, filtriert die ausgeschiedene     1-Phenyl-          keton-2-oxynaphtalin-6-sulfosäure    ab und rei  nigt sie durch     Umkristallisieren    ihres Na  triumsalzes.



      Process for the preparation of an aryloxynaphthylketous. It has been found that an aryl oxynaphtyl ketone can be produced if one responds to 2-oxynaphthalene-6-sulfonic acid, with or without the addition of diluent. Condensation agents, but with the exclusion of alkalis, benzotrichloride can act The 1-phenylketone-2-oxynaphthalene-6-sulfonic acid obtained in this way forms a white powder which dissolves in caustic alkalis and in concentrated sulfuric acid with a yellow color.

      <I> Example: </I> 19.5 parts of benzotrichloride and 22.4 parts of 2-oxynaphthalene-6-sulfonic acid are added to 100 parts of concentrated sulfuric acid at room temperature and stirred together until hydrochloric acid no longer develops. This is then poured into water, the precipitated 1-phenyl ketone-2-oxynaphthalene-6-sulfonic acid is filtered off and it is purified by recrystallizing its sodium salt.
