Claims52
An aerosol comprising at least one fluoroalkene of Formula I:
- XCFzR3-z (I)
- where X is a C1, C2, C3, C4, or C5 unsaturated, substituted radical, each R is independently Cl, F, Br, I or H, and z is 1 to 3, provided that X has a terminal ═CH2 group and further provided that the compound includes a halogen substituent on an unsaturated non-terminal carbon.
A sprayable admixture comprising a material to be sprayed and a propellant comprising at least one fluoroalkene of Formula I:
- XCFzR3-z (I)
- where X is a C1, C2, C3, C4, or C5 unsaturated, substituted radical, each R is independently Cl, F, Br, I or H, and z is 1 to 3, provided that X has a terminal ═CH2 group and further provided that the compound includes a halogen substituent on an unsaturated non-terminal carbon.
