Fluorocarbon separation process

摘要

A process for removing the vapors of certain fluoro(alkyl vinyl ethers) from a mixture with the vapor of tetrafluoroethylene by contacting the mixture of vapors with a chilled aqueous liquid coolant solution that is substantially immiscible with the ethers. The process provides an advantageous method for recovering the fluoro(alkyl vinyl ether) monomer remaining in the polymerization kettle after it has been copolymerized with tetrafluoroethylene.
