Abstract
This application relates to compositions comprising one or more partially fluorinated epoxides and/or one or more perfluorinated epoxides which may be useful in applications including refrigerants, air conditioning, heat transfer media, high-temperature heat pumps, organic Rankine cycles, fire extinguishing/fire suppression, propellants, foam blowing, solvents, dielectrics, and/or cleaning fluids.
Claims41
A composition for use in refrigeration, in air conditioning, in heating, in heat transfer, in conversion of heat into mechanical work in a power cycle, as a foam blowing agent, as a solvent, or in preventing or quenching an electric discharge, comprising a refrigerant component, an air conditioning component, a heating component, a heat transfer component, a working fluid component, a blowing agent component, a solvent component, or a dielectric component, respectively, which is a compound of Formula (I):
- wherein:
- R1 and R4 are each independently H, Cl, F, Br, I, a partially fluorinated C1-4 alkoxy, or a perfluorinated C1-4 alkoxy;
- and
- R2 is selected from H, Cl, F, Br, I, a partially fluorinated C1-10 alkyl, a perfluorinated C1-10 alkyl, a partially fluorinated C1-4 alkoxy, and a perfluorinated C1-4 alkoxy;
- wherein at least one of R1, R2, and R4 is not H;
- R3 is selected from partially fluorinated C1-10 alkyl and perfluorinated C1-10 alkyl;
- or alternatively, R2 and R3 are each independently selected from partially fluorinated or perfluorinated C1-5 alkylene, which together form a monocyclic ring.
