摘　　要：研究了高分子担载水杨醛半胱氨酸希夫碱配合物(PS-Sal-Cys-M)催化氧化环己烯的性能,详细探讨了反应温度、反应时间、催化剂用量、反应添加剂对高分子担载水杨醛半胱氨酸希夫碱铜配合物催化氧化环己烯的反应性能的影响。研究表明,在常压下,用分子氧作作为氧化剂,不需要溶剂及共还原剂,环己烯可以被氧化生成环己烯醇和环己烯酮,产物的分离提纯比较容易,催化剂可以循环使用。The catalytic oxidation for cyclohexene with polymer bound L-Cysteine salicylaldehyde schiff-base complexes （PS-SalCys-M） was investigated in this paper, a detailed study on the oxidation of cyelohexene with PS-SalCys-Cu was made, such as reaction temperature, reaction time, catalyst use level, and additives, the reusability of PS-Sal-Cys-Cu on catalytic oxidation of cyclohexene had been studied. It is shown that cyciohexene can be directly oxidized bu oxygen when catalyzed by PS-Sal-Cys- Cu without solvent and reductants. The major products of the reaction for cyclohexene were 2- cyclohexen-l-ol, 2-cyclohexen-l-one. The catalytic activity of PS-SalCys-Cu was maintained until the 4th circle.
