An aromatic ketone having the formula XArCOPhPhOH is made by contacting an ester of formula XArCOOPhPh, where
Ar is a divalent mono- or poly - aromatic group which may optionally be substituted;
Ph is para-phenylene; and
X is hydrogen or halogen or a nitro-, alkylsulphonyl-, arylsulphonyl-, alkylcarbonyl- or hydrocarbon group with a Friedel Crafts catalyst comprising one or more Lewis acids in an amount of at least 2.2 moles of such catalyst for each mole of the ester.
式 XArCOPhPhOH 的芳香族酮通过与式 XArCOOPhPh 的酯接触制成,其中
Ar 是二价单-或多-芳香基团,可任选被取代;
Ph 是对位亚苯基;以及
X 为氢或卤素或硝基、烷基磺酰基、芳基磺酰基、烷基羰基或烃基,与由一种或多种路易斯酸组成的 Friedel Crafts 催化剂接触,其用量为每摩尔酯至少 2.2 摩尔此类催化剂。
