丙氨酸席夫碱锰配合物对环己烯催化环氧化性能的研究

The Epoxidation of Olefins with Molecular Oxygen Catalyzed by Alanine Schiff Base Complex (Sal-Ala-Mn)

利用丙氨酸和水杨醛合成了席夫碱 Mn (Ⅲ) 配合物(Sal-Ala-Mn).以分子氧为氧源,异丁醛为共还原剂,研究了 Sal-Ala-Mn对环己烯氧化的催化性能,考察了温度、时间、催化剂量、异丁醛量、溶剂量对反应的影响.

The Alanine schiff base was synthesized by the reaction of Alanine with salicylaldehyde first. Then it was used as a ligand to coordinate with Mn Ac to obtain a complex (Sal-Ala-Mn). The catalytic property of the 2 complex on the epoxidation of cyclohexene with molecular oxygen as the oxygen source and isobutyraldehyde as the co-reducing agent was studied. The influencing factors to the catalysis, including reaction temperature, reaction time, quantities of the catalyst and isobutyraldehyde, volume of solvent were investigated at the same time.
