ABSTRACT:
Provided are azeotropic and azeotrope-like mixtures of 1,1,1,3,3-pentafluoropropane (HFC-245fa) and hydrogen fluoride. Such are useful as an intermediate in the production of HFC-245fa. The latter is useful as a nontoxic, zero ozone depleting fluorocarbon useful as a solvent, blowing agent, refrigerant, cleaning agent, aerosol propellant, heat transfer medium, dielectric, fire extinguishing composition and power cycle working fluid.
