Abstract (en)
[origin: WO0069797A1] Preparation of HFC 227ea by reacting HFP with hydrogen fluoride comprising the steps of charging the reaction mixture therefrom to a liquid-phase separator, allowing a HFC 227ea-rich phase and a hydrogen fluoride-rich phase to separate under gravity, recycling the separated hydrogen fluoride-rich phase, charging the HFC 227ea-rich phase to a distillation column, recovering the HFC 227ea and an HF-rich mixture separately from the distillation column; and recycling the HF-rich mixture to the reactor.
