PRODUCTION OF 1,1,1,2,3,3,3-HEPTAFLUOROPROPANE

摘要

Preparation of HFC 227ea by reacting HFP with hydrogen fluoride comprising t he 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 separa te under gravity, recycling the separated hydrogen fluoride-rich phase, chargin g the HFC 227ea-rich phase to a distillation column, recovering the HFC 227ea and an HF-rich mixture separately from the distillation column; and recyclin g the HF-rich mixture to the reactor.
