Abstract:The development circumstance of olefin catalyzing and epoxidation are simply introduced in this paper, and the material method of olefin catalyzing and epoxidation are discussed, which include catalyzing and epoxidation reaction of olefin gas and solid phase, catalyzing and epoxidation reaction of olefin liquid phase, catalyzing and epoxidation reaction of simulation enzyme, olefin epoxidation reaction by using NaClO and H 2O 2 as oxygen resource and olefin directly catalyzing and epoxidation reaction by using light. When we apply H 20 2 as oxygen resource and olefin has been epoxidated, it should not pollute condition and make circumstance protect, and this clear method will widely used in organic synthesis.
