The present invention relates to compositions comprising HFC-63-14mcee. The compositions may be azeotropic or azeotrope-like and are useful in cleaning applications, as a defluxing agent, for removing oils or residues from a surface, depositing or removing lubricants from a surface, and as refrigerants or heat transfer fluids in refrigeration systems, air-conditioners and heat pumps.

Compositions comprising 1,1,1,2,2,3,4,5,5,6,6,7,7,7-tetradecafluoroheptane and uses thereof

Azeotropic or azeotrope-like compositions comprising effective amounts of 1,1,1,2,3,4,4,5,5,5-decafluoropentane and cyclohexane or 1,1,1,2,3,4,4,5,5,5-decafluoropentane, cyclohexane and acetone to form an azeotropic or azeotrope-like composition that are useful as cleaning agents, displacement drying agents, wipe solvents, refrigerants, aerosol propellants, heat transfer media, gaseous dielectrics, fire extinguishing agents, expansion agents for polyolefins and polyurethanes and as power cycle working fluids are described.

Decafluoropentane compositions

Compositions of nonafluoromethoxybutane and cyclopentane, nonafluoromethoxybutane and cyclohexane; nonafluoromethoxybutane, cyclopentane and acetone, nonafluoromethoxybutane, cyclohexane and acetone, nonafluoromethoxybutane, trans-1,2-dichloroethylene and cyclopentane; and nonafluoromethoxybutane, trans-1,2-dichloroethylene, cyclopentane and methanol are described. These compositions are useful as cleaning agents, displacement drying agents, refrigerants, heat transfer media, expansion agents for polyolefins and polyurethanes, aerosol propellants, gaseous dielectrics, fire extinguishing agents, power cycle working fluids, polymerization media, particulate removal fluids, carrier fluids, and buffing abrasive agents.

Nonafluoromethoxybutane compositions

Compositions of nonafluoromethoxybutane and at least one component selected from the group consisting of methanol, ethanol, isopropanol, n-heptane, trans-1,2-dichloroethylene, cis-1,2-dichloroethylene and acetone, and 1,1,1,2,3,4,4,5,5,5-decafluoropentane are described. These compositions are useful as cleaning agents, displacement drying agents, refrigerants, heat transfer media, expansion agents for polyolefins and polyurethanes, aerosol propellants, gaseous dielectrics, fire extinguishing agents, power cycle working fluids, polymerization media, particulate removal fluids, carrier fluids, and buffing abrasive agents.
