A series of porous silica support metal Schiff-base complexes was synthesized with amino porous silica, salicylaldehyde and metal ion, which characterized by IR spectra, elemental analysis, and SEM. The catalytic property for oxidation of olefins in the presence of molecular oxygen has been investigated. The major product of the aerobic oxidation without reductant was the epoxy. The influence of reaction temperature and additive for epoxidation had been studied. The selectivity and the conversion of epoxidation varied with reaction time, different additives and different catalysts.
