IdentificationSynonyms: 1,1,1,2,2-Pentafluoroethane (IUPAC); Hydrofluorocarbon 125; R-125; FC-125De: Pentafluorethan ES: Pentafluoroetano Fr: PentafluoroéthaneCAS No.:354-33-6 EC No: 206-557-8 RTECS No.: KI6365000Molecular Weight: 120.022Molecular Formula: C2HF5b.p. (1 atm): -48.45°Cm.p.: -103°CODP: 0GWP: 3400 (CO2=1)Chemical and Physical properties: Stable in normal condition, HFC-125 is odorless, colorless, electrically non-conductive, non-corrosive, and leaves no residuePreparation:HFC-125 (pentafluoroethane) is made by process of gas-phase fluoridation between perchloroethylene (PCE) and hydrofluoric acid (HF). The intermediates of reaction are HCFC-123 and HCFC-124Application1) With zero ODP, HFC-125 is mainly used as a component of azeotropic blend refrigerant such as R-404a, R-407a, R-407b, R-407c, R-407d, R-410a and R410b (for more information, please see …).2) HFC-125 is also used in clean agent fire suppression system in enclosed space with situations where water from a fire sprinkler would damage expensive equipment or where water-based fire protection is impractical, such as museums, banks, clean rooms and hospitals. It is altenative for CFC-502, Halon-1211 and Halon-1301SpecificationParametersSpecificationHFC-125 purity99.8% minmoisture10 ppm maxAcidity as (HF)1 ppm max.Evaporation residues0.01%maxVisible foreign substancenoStandard Packaging790kg, 870kgs net/steel cylinder; ISO TankRisks and Safety InfoUN 3220.
