    摘要： Disclosed are compositions useful in a wide variety of applications, including heat transfer fluids which possess a highly desirable and unexpectedly superior combination of properties, and heat transfer systems and methods based on these fluids. The preferred heat transfer fluid comprises from about 1 to about 40 percent, on a weight basis, of carbon dioxide (CO2) and from about 99 to about 60 percent, on a weight basis, of a compound having the Formula I XCFzR3-z (I), where X is a C2 or a C3 unsaturated, substituted or unsubstituted, alkyl radical, each R is independently Cl, F, Br, I or H, and z is 1 to 3. A preferred compound of Formula I is tetrafluoropropene, particularly 1,1,1,3-tetrafluoropropene and/or 1,1,1,3-tetrafluoropropene.

    摘要： Azeotropic and azeotrope-like compositions of methyl iodide and at least one fluorocarbon or hydrofluorocarbon such as 1,1,1,3,3-pentafluoropropane (HFC-245fa). The compositions are present as a gas, at temperatures of about 30° C. or below. The inventive compositions serve as a non-ozone-depleting gaseous fumigant which is useful in a variety of applications, in place of methyl bromide. These compositions serve as a drop-in replacement for gaseous methyl bromide, providing the benefits of a methyl iodide fumigant while also utilizing existing methyl bromide equipment.
