MANUFACTURING METHOD OF HEXAFLUOROPROPYLENE-OXIDE WITH HIGH YIELD

摘要

A method for preparing a hexafluoropropylene-oxide is provided to obtain the hexafluoropropylene-oxide with high efficiency by increasing a contact interface of an organic phase with an aqueous solution phase through a two phase interface reaction under a phase-transition catalyst and a non-ionic surfactant. A method for preparing a hexafluoropropylene-oxide comprises a step of performing two phase interfacial reaction on an organic phase including hexafluoropropylene and an aqueous solution including hypochlorite in the existence of a phase-transition catalyst using 0.1-5 wt.% of a non-ionic surfactant such as a compound having an amine oxide group and a terminal 3-21 perfluoroalkyl group at regarding total weight of two solutions.
