摘要：
The conversion of phenyl acetate over AlPO4 (Al/P=1), γ-Al2O3 and SiO2 catalysts generated phenol, by deacetylation, ando-hydroxycetophenone, by Fries rearrangement, as the main reaction products. The activity for Fries rerrangement was in accordance with the acidity data measuredversus cyclohexene skeletal isomerization. Thus, AlPO4 showed the highest activity. Moreover,o-hydroxy-acetophenone formation increased with the reaction temperature. Besides, in AlPO4 catalysts 4-methylcoumarin and 2-methylchromone were also found, although in low amounts.
