Abstract
The use of pentafluoropropene (HFO-1225) and tetrafluoropropene (HFO-1234) in refrigeration equipment is 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.
Claims23
A heat transfer composition comprising:
- (a) at least one fluoroalkene of Formula I:
- XCFz (I)
- where X is a C2 or a C3 unsaturated, substituted or unsubstituted, alkyl radical and z is 1 to 3;
- and
- (b) a lubricant.
A method of transferring heat to or from a fluid or body comprising causing a phase change in a fluoroalkene of Formula I:
- XCFz (I)
- where X is a C2 or a C3 unsaturated, substituted or unsubstituted, alkyl radical and z is 1 to 3.
A method of forming a foam comprising adding to a foamable composition a blowing agent comprising at least one fluoroalkene of Formula I:
- XCFz (I)
- where X is a C2 or a C3 unsaturated, substituted or unsubstituted, alkyl radical and z is 1 to 3.
