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飒 氧酞菁铁含量、酞菁铁结晶度和表面形态有关.

关键词: 环己烯, 催化氧化, 酞菁铁(FePc)

Abstract: 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.

Key words: Cyclohexene, Catalytic oxidation, Iron phthalocyanine(FePc)
