摘要
合成了新型配体组氨酸水杨醛席夫碱Ｍｎ（Ⅱ）配合物（Ｓａｌ－Ｈｉｓ－Ｍｎ），通过红外光谱、紫外光谱、原子吸收光谱、ＸＰＳ等分析对其结构进行了表征．以分子氧为氧源，研究了Ｓａｌ－Ｈｉｓ－Ｍｎ对环己烯烯丙位氧化的催化性能，考察了温度、时间、溶剂、氧压力等因素对反应的影响．
The L-histidine schiff base complex (Sal-His-Mn) has been s ynthesized. Its structure has been characterized by infrared spectra, electronic spectra, atomic absorption spectra and X-ray photoelectron spectra. The cataly tic activity of the complex in the cyclohexene oxidation by oxygen molecule has been studied. The influence of reaction temperature, time, solvents and oxygen p ressure on the oxidation have been determined. The results show that when the ox idation is carried out under the reaction conditions of 60～100℃, 5～11h and 1. 0～2.0 MPa O2,the main product is cyclohexene-2-one. The conversion of cycl ohexene increases with the rise of the reaction temperature, time and oxygen pres sure.
