Abstract: This paper reviews the new research progress of epoxidation of propylene with different oxidants. It includes propylene epoxidation with hydrogen peroxide in-situ synthesized using hydrogen and oxygen，photoepoxidation of propylene and oxygen and reactions with ozone and nitrous oxide as oxidants. It indicates that the major task is development of active and selective catalysts. The application prospect of new processes is also discussed.
