Description

  

  Verfahren zur Herstellung eines     4-0xynaphtalin-l-arylketons.       Es wurde gefunden, dass man ein     4-Oxy-          naphtalin-l-arylketon,    das     4-Oxynaphtalin-l-          phenylketon,    herstellen kann, wenn man die       4-Oxyn@a.phtalin-l-phenylketon-.3    -     sulfosäure     auf höhere Temperatur, vorzugsweise in Ge  genwart eines Verdünnungsmittels, erhitzt.  Das so gewonnene     4-Oxynaphtalin-l-phenyl-          lceton    bildet ein weisses Pulver, das, aus Ben  zol umgelöst, bei<B>165'</B> schmilzt und sich mit  gelber Farbe in Natronlauge löst.  



  <I>Beispiel:</I>  100 Teile     4-Oxynaphtalin-l-phenylketon-          3-sulfosäure    werden mit 400 Teilen 5     %iger     Schwefelsäure in einem     geschlossenen    Gefäss  auf<B>180'</B> bis<B>190'</B> erwärmt. Das in fast rei  nem Zustand erhaltene 4 -     Oxynaphtalin    - 1     -          phenylketon    kann noch aus Benzol umgelöst  werden.



  Process for the preparation of a 4-oxynaphthalene-1-aryl ketone. It has been found that a 4-oxynaphthalene-1-aryl ketone, the 4-oxynaphthalene-1-phenyl ketone, can be produced if the 4-oxyn@a.phtalin-1-phenyl ketone-3-sulfonic acid is higher Temperature, preferably in the presence of a diluent, heated. The 4-oxynaphthalene-1-phenyl-acetone obtained in this way forms a white powder which, dissolved from benzene, melts at <B> 165 '</B> and dissolves in caustic soda with a yellow color.



  <I> Example: </I> 100 parts of 4-oxynaphthalene-1-phenylketone-3-sulfonic acid are mixed with 400 parts of 5% sulfuric acid in a closed vessel to <B> 180 '</B> to <B> 190' </B> heated. The 4 - oxynaphthalene - 1 - phenyl ketone, which is obtained in an almost pure state, can still be dissolved from benzene.
