摘要:

研究了一种将苯甲醇直接氧化成苯甲醛的催化体系:氯化金属卟啉/离子液体/氧化剂(MTPPCl/ILs/[O]),考察了该体系反应过程中温度、氯化金属卟啉、氧化剂、轴向配体和离子液体的种类等因素对反应收率的影响。 结果表明,催化剂氯化锰卟啉、溶剂1-丁基-3-甲基咪唑硫酸氢盐离子液体、氧化剂过硫酸钾组成的催化体系MnTPPCl/[Bmim]HSO4/K2S2O8在苯甲醇直接催化氧化成苯甲醛的反应中表现出很好的活性(>99%)和选择性(>99%),且该体系避免了使用传统的有机溶剂,可重复多次使用。

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
