Abstract:The L-histidine schiff base complex (Sal-His-Mn) has been synthesized. Its structure has been characterized by infrared spectra, electronic spectra, atomicabsorption spectra and X-ray photoelectron spectra. The catalytic activity of the complex in the cyclohexene oxidation by oxygen molecule has been studied. The influence of reaction temperature, time, solvents and oxygen pressure on the oxidation have been determined. The results show that when the oxidation is carried out under the reaction conditions of 60~100℃, 5~11h and 1. 0~2.0 MPaO2, the main product is cyclohexene-2-one. The conversion of cyclohexene increases with the rise of the reaction temperature, time and oxygen pressure.
Keywords:L-histidine schiff base manganese complex  synthesis  cyclohexene  catalytic oxidation
