ABSTRACT:
Hydroxy substituted arylophenones in general, and 4,4'-dihydroxybenzophenones in particular, are produced by catalytic oxidation of diaryl compounds containing hydroxy substituted diaryl moieties in a liquid medium. Oxidation occurs by contact of the diaryl compounds with an oxygen-containing gas in the presence of a solvent, base, a metal atom catalyst, and optionally, activated carbon. The arylophenones produced are useful as monomers in the production of epoxy and polycarbonate resins.
