Abstract
The present application provides stabilized compositions (e.g., stabilized heat transfer fluids) comprising methyl perfluoroheptene for use, for example, in refrigeration and heat transfer applications. The stabilized compositions of the present invention are useful in methods for producing cooling and heating, methods for replacing refrigerants and refrigeration, air conditioning, heat pump apparatuses, and as solvents or dewatering agents.
Claims24
A composition, comprising:
- i) methyl perfluoroheptene ether;
- and
- ii) a second component selected from the group consisting of butylated hydroxy toluene, hydroquinone monomethyl ether, 2-tert-butyl-6-methylphenol, 2-tert-butyl-5-methylphenol and 2-tert-butyl-4-ethylphenol 1,3-dioxolane, 1,2-epoxybutane and nitromethane, or any mixture thereof.
The composition of claim 5, wherein the composition comprises about 100 ppm to about 550 ppm of the second component.
A method of reducing acidic degradation of a working fluid comprising methyl perfluoroheptene ether, comprising mixing the working fluid with a second component selected from the group consisting of one or more antioxidants and one or more acid scavengers, or any mixture thereof, thereby forming a stabilized working fluid.
