Abstract 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.
Key words Hexafluoropropylene oxide, Oxidation, Molecular oxygen, Preparation

摘 要 对合成有机氟材料的重要中间体棗六氟环氧丙烷的制备研究进展进行了综述。现有制备工艺中都是用六氟丙烯氧化法。所用的氧化剂有过氧化氢、分子氧、次氯酸盐、有机过氧化物、碳酸盐等。在所有氧化剂中，分子氧是最理想的氧化剂，但仍然存在一些问题，有待进一步研究。此外对六氟环氧丙烷的分离提纯工艺也作了概述。
