Description

  

  Verfahren zur Herstellung eines     Aryloxynaphtylketons.       Es wurde gefunden, dass man ein     Aryloxy-          naphtylketon    herstellen kann, wenn man auf       1.-Oxynaphtalin-2-sulfosäure,    mit oder ohne  Zusatz von     Verdünnungs-        bezw.    Kondensa  tionsmitteln, aber unter Ausschluss von Al  kalien,     Benzotrichlorid    einwirken lässt. Die  so gewonnene     1.-Phenylkeion-4-oxynaphtyl-3-          sulfosä.ure    bildet ein weisses Pulver, welches  sich in     Ätzalkalien    und in konzentrierter       Schwefelsäure    mit gelber Farbe löst.  



  <I>Beispiel:</I>  1.9,5 Teile     Benzotrichlorid    und 22.4 Teile  1. -     Oxynaphtalin    - 2 -     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 Wasser.  filtriert die ausgeschiedene     1-Phenyl-keton-4-          oxyna,phtyl-3-sulfosäure    ab und     reinigt    sie  durch     Umkristallisieren    ihres     Natriumsalzes.  



  Process for the preparation of an aryloxynaphthyl ketone. It has been found that an aryloxy naphthyl ketone can be produced if one responds to 1.-oxynaphthalene-2-sulfonic acid, with or without the addition of diluent or. Condensation agents, but with the exclusion of alkalis, allows benzotrichloride to act. The 1.-phenyl-4-oxynaphthyl-3-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> 1.9.5 parts of benzotrichloride and 22.4 parts of 1. - oxynaphthalene - 2 - sulfonic acid are added to 100 parts of concentrated sulfuric acid at room temperature and stirred together until hydrochloric acid no longer develops. Then you pour in water. the precipitated 1-phenyl-ketone-4-oxyna, phtyl-3-sulfonic acid is filtered off and purified by recrystallizing its sodium salt.
