FePc结构对 Pd(OAc)2/HQ/FePc催化环己烯氧化活性的影响

摘要

在乙腈酸性水溶液中 ,不同来源酞菁铁 (FePc)和 Pd(OAc)2/HQ(氢醌)组成的催化体系在环己烯氧化反应中有明显不同的催化活性 .通过 IR、 M ssbauer、 XPS、 XRD、 SEM、 BET等技术对酞菁铁的分析表明 ,由酞菁铁组成的多组份催化体系的催化活性与酞菁铁中的μ氧酞菁铁含量、酞菁铁结晶度和表面形态有关 .%In an acidic aqueous solution of acetonitrile,the catalytic activity of the catalysts consisted of Pd(OAc)2/hydroquinone(HQ) with iron phthalocyanine (FePc) from various sources was obviously different in the oxidation of cyclohexene to cyclohexanone.The analysis of the FePc using IR spectroscopy,M ssbauer spectroscopy,X ray photoelectron spectroscopy (XPS),X ray powder diffraction (XRD),scanning electron microscopy(SEM) and BET surface area measurement indicated that the catalytic activity of the multicomponent catalytic system composed of iron phthalocyanines depends on the amount of μ  oxo FePc,the crystallinity and the surface structure of iron phthalocyanine.
