ABSTRACT:
A process is provided for the production of 2-hydroxyphenyl lower alkyl ketones, e.g. 2-hydroxyacetophenone, by reacting phenol and a lower alkanoic acid, e.g. acetic acid or an ester of phenol and a lower alkanoic acid, e.g. phenyl acetate, in the presence of a silicalite catalyst containing about 700 to 14000 ppm of alumina, which has been calcined at least once from the as synthesized form. The reaction is preferably conducted in the vapor phase in the presence of an inert gas such as nitrogen.
