Abstract
PURPOSE:To effectively utilize a by-product obtained in preparing hexafluoropropene and advantageously obtain the titled compound, by oxidizing heptafluoroisobutenyl alkyl, aryl or benzyl ether with ozone. CONSTITUTION:A lower alcohol, phenols or benzyl alcohol is added to heptafluoroisobutene formed in producing hexafluorobenzene useful as a raw material for fluorine-containing copolymers and the resultant adduct is then subjected to dehydrofluorination reaction to provide a heptafluoroisobutenyl alkyl, aryl or benzyl ether, which is subsequently oxidized with ozone in the absence of presence of a solvent, such as hydrocarbon, halogenated hydrocarbon, ether or water, preferably at -40-+60 deg.C to advantageously afford the aimed hexafluoroacetone or a hydrate thereof useful as a monomer for producing synthetic polymers or rubbers, etc.
