Abstract

Olefin epoxidation is of academic and industrial importance in modern chemistry. However

olefin epoxidation is still quite a challenge due to the difficulty of mass transfer when using the green oxidant hydrogen peroxide. A novel tungsten-based catalyst for epoxidation was prepared using an oxidative condensation method

and was applied to study the effect on epoxidation of cyclohexene with commercially available hydrogen peroxide as an oxidant. The conversion of cyclohexene (51.2%) and selectivity to cyclohexene oxide (69.2%) were obtained under a certain reaction condition. It exhibited high catalytic activity and good selectivity towards cyclohexene oxide under mild conditions without any solvent and with less environmental contaminations.
