Description

  

  Verfahren zur Herstellung eines     Arylogynaphtyllietons.       Es wurde gefunden,     dass    man ein     Aryloxy-          naphtylketon    herstellen kann,     wenn.man    auf       1-Oxynaphtalin-5-sulfosäure,    mit oder ohne  Zusatz von     Verdünnungs-        bezw.    Kondensa  tionsmitteln, aber unter Ausschluss von     Al-          kalien,        Benzotrichlorid    einwirken lässt.

   Die  so gewonnene     2-Phenylketon-l-oxynaphtyl-5-          sulfosäure    bildet ein weisses Pulver, welches  sich in     Ätzalkalien    und in konzentrierter  Schwefelsäure mit gelber     Farbe    löst.    <I>Beispiel:</I>    19,5 Teile     Benzotrichlorid    und 22,4 Teile  1 -     Oxynaphtalin    - 5 -     sulfosäure    werden bei  Zimmertemperatur 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     2-Phenyl-          keton-l-oxynaphtyl-5-sulfosäure    ab und rei  nigt sie durch     Umkristallisieren    ihres Na  triumsalzes.



  Process for the preparation of an arylogynaphthyl acetate. It has been found that an aryloxy naphtyl ketone can be produced if you use 1-oxynaphthalene-5-sulfonic acid, with or without the addition of diluent or. Condensation agents, but with the exclusion of alkalis, allows benzotrichloride to act.

   The 2-phenylketone-1-oxynaphthyl-5-sulfonic acid obtained in this way forms a white powder which dissolves in caustic alkalis and concentrated sulfuric acid with a yellow color. <I> Example: </I> 19.5 parts of benzotrichloride and 22.4 parts of 1 - oxynaphthalene - 5 - sulfonic 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 2-phenylketone-1-oxynaphthyl-5-sulfonic acid is filtered off and it is purified by recrystallizing its sodium salt.
