| 摘要 |
Various uses of tetrafluoropropenes, particularly (HFO-1234) in a variety of applications, including refrigeration equipment, are disclosed. These materials are generally useful as refrigerants for heating and cooling, as blowing agents, as aerosol propellants, as solvent composition, and as fire extinguishing and suppressing agents. |

1. A composition comprising:
(a) at least one fluoroalkene of Formula I:
XCFzR3-z (I)where X is a C1, C2, C3, C4, or C5 unsaturated, substituted or unsubstitued radical, each R is independently Cl, F, Br, I or H, and z is 1 to 3, provided that if Br is present in the compound then the compound includes no hydrogen and further provided that the compound has at least four (4) halogen substituents; and
