Abstract

Phenol acylation on Hβ, CeHβ and SO4 2-/ZrO2 using acetic acid and acetic anhydride as acylating agents is compared in the temperature range 250-400°C. Acetic acid formed phenyl acetate (PA) and o-hydroxy acetophenone (o-HAP) and acetic anhydride formed p-hydroxyacetophenone (p-HAP ) along with PA and o-HAP. The formation of o-HAP and p-HAP, the products of C-acylation of phenol using acetic acid is proposed by studying phenyl acetate conversion on Hb, CeHβ and SO4 2-/ZrO2. Our studies show that for phenol acylation the most suitable acid site is available on CeHβ.
