Abstract
A perfluorinated 1-alkoxypropene represented by general Formula (I), compositions that include such compounds, and methods and systems that include such compositions are provided, wherein Formula (I) is represented by: RfO—CF═CFCF3 wherein Rf is a linear, branched, or cyclic perfluoroalkyl group having 2 to 10 carbon atoms and optionally further including 1 to 3 nitrogen and/or 1 to 4 oxygen catenary heteroatoms.
Claims20
An apparatus for heat transfer comprising:
- a device;
- and
- a mechanism for transferring heat to or from the device, the mechanism comprising a heat transfer fluid comprising a perfluorinated 1-alkoxypropene compound represented by the following general Formula (I):
- RfO—CF═CFCF3 I
- wherein Rf is a linear, branched, or cyclic perfluoroalkyl group having 2 to 10 carbon atoms and optionally further including 1 to 3 nitrogen and/or 1 to 4 oxygen catenary heteroatoms;
- with the proviso that Rf is not a branched perfluoroalkyl group having 3 carbon atoms and no heteroatoms.
A method of transferring heat comprising:
- providing a device;
- and
- transferring heat to or from the device using a heat transfer fluid comprising a perfluorinated 1-alkoxypropene compound represented by the following general Formula (I):
- RfO—CF═CFCF3 I
- wherein Rf is a linear, branched, or cyclic perfluoroalkyl group having 2 to 10 carbon atoms and optionally further including 1 to 3 nitrogen and/or 1 to 4 oxygen catenary heteroatoms;
- with the proviso that Rf is not a branched perfluoroalkyl group having 3 carbon atoms and no heteroatoms.
