Description

  

  Verfahren zur Herstellung eines     Aryloaynaphtylketons.       <B>Es</B> wurde gefunden,     .dass    man ein     Aryl-          oxynaphty        lketon    herstellen kann, wenn man  auf     1-Oxynaphthalin-2-carbonsäure,    mit oder  ohne Zusatz von     Verdünnungs-        bezw.    Kon  densationsmitteln, aber unter Ausschluss von       Alkalien,        2,4-Diclilorbenzotrichlorid    einwir  ken lässt.

   Die so gewonnene 1-(2' .     4'-Dichlor-          phenyl)-        l#.eton-4-oxynaphtyl    - 3 -     carbonsäure          bildet    weisse Nadeln, die bei 201 ' unter Zer  setzung schmelzen und sich in     Ätzalkalien     und in konzentrierter Schwefelsäure mit gel  ber Farbe     lösen.     



       Beispiel:     26,4 Teile     2,4-Dichlorbenzotrichlorid    und  <B>18,8</B> Teile     1-Oxynaphtalin-2-carbonsäure    wer  den bei Zimmertemperatur in 100 Teile kon  zentrierte Schwefelsäure eingetragen und so  lange zusammen gerührt, bis sich keine Salz  säure mehr entwickelt. Hierauf giesst man in       Wasser,    filtriert die ausgeschiedene 1-(2' . 4'       I)ieliloiThenyl)-heton-4-oxynaphtyl-3=carbon-          Aure    ab und reinigt sie durch     Umkristalli-          sieren    ihres     Natriumsalzes.  



  Process for the production of an aryloaynaphthyl ketone. It has been found that an aryl oxynaphthalene ketone can be produced if one uses 1-oxynaphthalene-2-carboxylic acid, with or without the addition of diluent or. 2,4-diclilobenzotrichloride can act as condensation agents, but with the exclusion of alkalis.

   The 1- (2 '. 4'-dichlorophenyl) - l # .eton-4-oxynaphthyl - 3 - carboxylic acid obtained in this way forms white needles which melt at 201' with decomposition and are incorporated into caustic alkalis and concentrated sulfuric acid dissolve yellow over color.



       Example: 26.4 parts of 2,4-dichlorobenzotrichloride and 18.8 parts of 1-oxynaphthalene-2-carboxylic acid are added to 100 parts of concentrated sulfuric acid at room temperature and stirred together until none Hydrochloric acid more developed. It is then poured into water, the precipitated 1- (2 '. 4' I) ieliloiThenyl) -hetone-4-oxynaphthyl-3-carbonic acid is filtered off and purified by recrystallizing its sodium salt.
