In this paper, various methods of preparing hexafluoropropylene oxide, which is an important intermediate for synthesizing organic fluoric materials, were reviewed. In the present preparation technology, hexafluoropropylene oxide was prepared by oxidation of hexafluoropropylene. The oxidizers are hydrogen peroxide, molecular oxygen, hypochlorite, organic peroxide, carbonate and so on. Molecular oxygen is the most ideal one among these oxidizers, but there are some problems to be solved. The purification of hexafluoropropylene oxide was also summarized.
