ABSTRACT:
A process of acylating a monocyclic phenolic reactant, e.g. phenol to a hydroxy aromatic ketone, e.g. 4-hydroxyacetophenone, by contacting the phenolic reactant with about 0.4 to 0.8 moles of a carboxylic acid anhydride, e.g. acetic anhydride as acylating agent per mole of phenolic reactant of in the presence of a Friedel-Crafts catalyst, e.g. hydrogen fluoride. The process generally results in phenolic reactant conversions of at least about 80% and reaction selectivities to hydroxy aromatic ketone of at least about 70%.
