Abstract

The epoxidation of cyclohexene catalyzed by Schiff based manganese/zeolite was studied in this paper.The result showed that Schiff based manganese/zeolite immobilized by flexible ligand route,the yield of 1,2-cyclohexane could reach 83.38% and the conversion of cyclohexene was increased with the reaction time and temperature,while the yield of 1,2-cyclohexane was increased at first and decreased after 8h and 35 ℃.The catalytic activity of catalyst was reduceded by 2% after being recycled 3 times.
