Direct Oxidation of Benzene to Phenol on Manganese Pyrophosphate with Hydrogen Peroxide

Keywords: Benzene, Manganese Pyrophosphate, Repulsive Water Character, Oxidize

A solid catalyst manganese pyrophosphate based on non-sieves to oxidize benzene to phenol with oxidant hydrogen peroxide has shown good conversion with good selectivity in CH₃CN at 65°C investigating water contact angle data of three manganese salts, it is found manganese pyrophosphate has certain repulsive water character. It is further to be confirmed by benzene and phenol adsorption experiments onto catalyst surface by GC. With benzene/H₂O₂ ratio of 1, the benzene conversion of 13.8% with phenol selectivity of 85.0% was achieved. It is noteworthy that no any products are obtained using manganese pyrophosphate as catalyst in the oxidation of phenol in CH₃CN solvent.
