Description |
Direct hydroxylation of aromatic hydrocarbons, viz. benzene, toluene and anisole to phenol, cresols and
methoxyphenols respectively has been studied by using hydrogen peroxide as oxidant and vanadium
based systems such as vanadyl tetraphenoxyphthalocyanine, VO(acac)2, 20% V2O5/Al2O3, 14% V2O5/TiO2,
11% V2O5/ZiO2 as catalysts in acetonitrile under biphasic reaction conditions. Among the various
vanadium-based catalysts studied, vanadyl tetraphenoxyphthalocyanine (VOPc) was found to be best
from conversion as well as selectivity for hydroxy compounds points of view. The effect of various
reaction parameters such as H2O2/substrate molar ratio, reaction temperature, solvent and catalyst
concentration was systematically studied.
