    摘要: Disclosed are compositions and methods for cleaning contaminated articles based on the provision of a zeotropic composition comprising (a) at least one flammable solvent having a boiling point at a first pressure; (b) at least one first nonflammable solvent having a boiling point at said first pressure which is less than about said first pressure boiling point of said flammable solvent; and (c) at least one second nonflammable solvent having a boiling point at said first pressure which is greater than about the first pressure boiling point of said flammable solvent.

    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.

    摘要: Disclosed is an integrated manufacturing process to co-produce (E)1-chloro-3,3,3-trifluoropropene, (E)1,3,3,3-tetrafluoropropene, and 1,1,1,3,3-pentafluoro-propane starting from a single chlorinated hydrocarbon feed stock, 240fa. The process includes a combined liquid or vapor phase reaction/purification operation which directly produces (E)1-chloro-3,3,3-trifluoropropene (1233zd(E)) from 240fa. In the second liquid phase fluorination reactor 1233zd(E) is contacted with HF in the presence of catalyst to produce 1,1,1,3,3-pentafluoropropane (245fa) with high conversion and selectivity. A third reactor is used for dehydrofluorination of 245fa to produce (E)1,3,3,3-tetrafluoropropene (1234ze(E)) by contacting in the liquid phase with a caustic solution or in the vapor phase using a dehydrofluorination catalyst. This operation may be followed by one or more purification processes to recover the 1234ze(E) product.
