Patent ID: 8003832

Claim:
A process for recovering pentafluoroethane, comprising bringing a mixed gas containing pentafluoroethane and a non-condensable gas into contact with a chlorinated solvent to allow the chlorinated solvent to absorb pentafluoroethane contained in the mixed gas, wherein the mixed gas is a gas separated during production of pentafluoroethane, and wherein the mixed gas is a low-boiling fraction (C) occurring during the production of pentafluoroethane, the low-boiling fraction (C) being obtained by: (A) separating and recovering a gas component (A) by distillation, the gas component (A) containing at least pentafluoroethane and a non-condensable gas; and (C) separating the gas component (A) into a high-boiling fraction (C′) and a low-boiling fraction (C), the high-boiling fraction (C′) being based on pentafluoroethane and the low-boiling fraction (C) containing pentafluoroethane and the non-condensable gas.
