HFC-125 that is substantially free of CFC-115 can be produced in a process comprising contacting an HFC-125 precursor and an HFC-32 precursor with HF optionally over a catalyst to produce a mixture comprising HFC-125 and HFC-32, removing impurities other than CFC-115 from the mixture by distillation or other processes, separating the CFC-115 from the mixture comprising HFC-125 and HFC-32 by azeotropically distilling the low-boiling azeotrope of CFC-115 and HFC-32 overhead in a distillation column, and, recovering a mixture of HFC-125 with HFC-32 substantially free of CFC-115 from the bottom of the distillation column.
