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.
在
氟化氢存在下,
二苯醚和适当的酰基化合物发生反应,可制备出纯度较高的对苯氧基苯甲酰基化合物。 由此得到的对苯氧基芳基烷基酮可转化为对苯氧基
苯甲酸或其盐类、对苯氧基苯甲酰基卤化物或低级对苯氧基
苯甲酸烷基酯,用于制备含有对苯氧基苯甲酰基重复单元的均聚物和共聚物。
