The present invention provides a novel method for producing hexafluoropropylene oxide, which can attain a high HFPO selectivity without using a phase transfer catalyst. Hexafluoropropylene (HFP), a water-soluble and aprotic organic solvent, and an aqueous solution of an oxidizing agent are introduced into a small space, thereby bringing into contact with each other and reacting hexafluoropropylene with the oxidizing agent to obtain hexafluoropropylene oxide (HFPO).

1. A method for producing hexafluoropropylene oxide, which comprises introducing into a small space components including hexafluoropropylene, a water-soluble and aprotic organic solvent selected from the group consisting of acetonitrile, glyme and N,N-dimethylformamide, and an aqueous solution of sodium hypochlorite, thereby bringing these components into contact with each other in a dissolved phase; and reacting hexafluoropropylene with the sodium hypochlorite to obtain hexafluoropropylene oxide, wherein the method is conducted in the absence of any phase transfer catalyst. 2. The method according to claim 1, wherein the small space has a passage width of not less than 1 μm and not more than 1 cm.
