摘要
测定了色氨酸四苯基卟啉铁（Ⅲ）（简记为Fe〔Trp—TPP〕Cl）与锌粉、乙酸和咪唑组成的氧化模拟体系催化烯烃氧化的吸氧动力学曲线,研究了不同轴向配体对体系催化活性的影响。结果表明,该体系催化各类烯烃环氧化产物收率（Zn％）由高到低的顺序为:环已烯>1—癸烯>烯丙基丙酮>丙烯酸甲酯,用吡啶代替咪唑作轴向配体可明显提高体系的最高吸氧速度。
The oxygen uptake dynamical cure of oxidation minetic system for alkenes epoxidation is measured. The system consists of Fe[Trp-TPP]Cl,Im,Zn and CH3COOH. On the other hand it is studied that the effect of axial ligands on the catalytic activity of the system. The results show that the epoxidation yield of the system diminish as follows :Cycloohexene 1-decene allylaceton methylpropenoicate and the highest uptake oxygen rate will be increased by substituting Pyridine for imidazole.
