Abstract:

The direct oxidation of benzyl alcohol to phenyl aldehyde was studied with chloridized metallic porphyrin(MnTPPCl)/ionic liquid(ILs)/oxidant catalysts. The effects of temperature, MnTPPCl, various oxidation agents and the role of axial ligands on the yield were examined. The results showed that the yield and the selectivity of phenyl aldehyde can be both more than 99% in half an hour under the novel catalytic system MnTPPCl/[Bmim]HSO4/K2S2O8. The catalytic system without any organic solvents can be reused for many times and get a good performance.

Key words: metallic porphyrin, ionic liquids, benzyl alcohol, catalytic oxidation
