Formation of alkyl radicals that are relatively unreactive with each other and with oxygen, in the low-temperature liquid-phase oxidation of hexafluoropropylene by molecular oxygen

Abstract

Kinetic evidence has been found for the participation of stable alkyl radicals in the reaction of low-temperature liquid-phase oxidation of hexafluoropropylene by molecular oxygen. The presence of such stable radicals is proven by the nonparticipation of alkyl radicals in chain-breaking, and also by the formation of epoxide at significant rates when the oxygen pressure is high.
