The report gives results of a preliminary evaluation of a new hydrofluoro-carbon (HF)--HFC-245ca or 1,1,2,2,3-pentafluoropropane--as apossible alternative for chlorofluorocarbon (CFC)-11 (trichlorofluoromethane) and hydrochloro-fluorocarbon (HCFC)-123 (1,1,1-trifluoro- 2,2-dichloroethane) refrigerant for low-pressure chillers and as a possible alternative for CFC-111 and HCFC-14lb (1-fluoro-1,1-dichloroethane) blowing agents for polyisocyanurate/polyurethane insulation forms. Evaluation tests included an examination of its flammability, stability, thermophysical properties, lubricant miscibility and lubricity, materials compatibility, acute inhalation toxicity, and refrigeration performance.An azeotrope composed of HFC-245ca and HFC-338mccq (1,1,1,2,3,4,4,4-octafluorobutane) was also examined from the standpointof reducing the flammability of HFC-245ca.
