Role of chlorocarbon oligomers in the room-temperature heterogeneous catalytic fluorination of hydrochlorocarbons to hydrochlorofluorocarbons

Abstract

Radiotracer [¹⁸F] and [³⁶Cl] experiments demonstrate the deposition of oligomeric chlorocarbon species on fluorinated metal oxides and trapping of hydrochlorocarbon monomers, both without loss of surface fluoride lability, thus accounting for the unusual room-temperature heterogeneous catalytic fluorination of CH₃CCl₃ and related species by anhydrous HF.
