    Abstract: The invention relates to azeotropic and azeotrope-like mixtures of 1,2,2-trichloro-1,3,3,3-tetrafluoropropane (commonly known as HCFC-224aa, and with the IUPAC name of 2,2,3-trichloro-1,1,1,3-tetrafluoropropane;registry number 139754-75-9) and hydrogen fluoride (hydrofluoric acid), which are useful as intermediates in the production of 1,1,3,3,3-pentafluoropropane (HFC-245-fa) and 1,1,1,2,2,3,3-heptafluoropropane (HFC-227ca).

    Abstract: The invention relates to azeotropic and azeotrope-like mixtures of 1,1,1,3,3-pentachloropropane (HCC-240fa) and carbon tetrachloride and a process for separating the azeotrope-like mixtures. The compositions of the invention 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 and aerosol propellant.

    Abstract: Provided are methods of charging refrigerants into refrigeration systems. The present methods involve recharging a refrigerant system that contains a chlorine-containing refrigerant and a lubricant comprising the steps of (a) providing a refrigeration system comprising a chamber having a hydrocarbon-based lubricant and substantially no chlorofluorocarbon refrigerant; and (b) introducing to the system a composition comprising: (i) a refrigerant; (ii) a surfactant; and (iii) a solubilizing agent.
