Substantially pure p-phenoxybenzoyl compounds are prepared by reacting diphenyl ether and an appropriate acyl compound in the presence of hydrogen fluoride. The resulting p-phenoxyaryl alkyl ketone can be converted into p-phenoxybenzoic acid or salts thereof, p-phenoxybenzoyl halide or lower alkyl p-phenoxybenzoate for use in preparing homo- and copolymers containing a p-phenyxobenzoyl repeating unit.
