ABSTRACT:
A process for producing hexafluoropropylene oxide from hexafluoropropylene is described. The process comprises epoxidizing hexafluoropropylene in a two-phase system of an aqueous phase and an organic phase by the use of a hypochlorite as an oxidizing agent, the hypochlorite being dissolved or dispersed in the aqueous phase, in the presence of at least one catalyst selected from the group consisting of (a) quaternary ammonium salts, (b) quaternary phosphonium salts, (c) quaternary arsonium salts, and (d) lipophilic complexing agents for cations contained in the hypochlorite, and also, in the presence or absence of an inorganic base.
