摘要:
An azeotrope-like mixture consisting essentially of chlorotrifluoropropene and at least one component selected from the group consisting of a C1-C3 alcohol, a C5-C6 hydrocarbon, a halogenated hydrocarbon, methylal, methyl acetone, water, nitromethane, and combinations thereof.
摘要:
Provided are azeotropic or azeotrope-like mixtures of 1,1,3,3-tetrachloro-1-fluoropropane (HCFC-241fa) and hydrogen fluoride. Such compositions are useful as an intermediate in the production of HFC-245fa and HCFO-1233zd.
摘要:
The present invention pertains to azeotropic and azeotrope-like compositions of the following three blends: 1. Trans-1,3,3,3-tetrafluoropropene (HFO-1234ze(E)), cis-1,3,3,3-tetrafluoropropene (HFO-1234ze(Z)) and hydrogen fluoride (HF); 2. HFO-1234ze(E), 1,1,1,3,3-pentafluoropropane (HFC-245fa) and HF; and 3. HFO-1234ze(Z), HFC-245fa and HF. These azeotropic and azeotrope-like compositions are useful as intermediates in the production of HFO-1234ze(E).

摘要:
Provided are azeotropic and azeotrope-like compositions of 2,3-dichloro-3,3-difluoropropene (HCFO-1232xf) and hydrogen fluoride (HF). Such azeotropic and azeotrope-like compositions are useful as intermediates in the production of 2,3,3,3-tetrafluoropropene (HFO-1234yf)
摘要:
An azeotrope-like composition consisting essentially of 1,1,2,3-tetrachloropropene and hydrogen fluoride is provided, as well as methods that involve such an azeotrope-like composition.
摘要:
The invention relates to azeotropic and azeotrope-like mixtures of 1,1,1,3,3-pentafluorobutane (HFC-365) and hydrogen fluoride and a process for separating the azeotrope-like mixtures. The compositions of the invention are useful as an intermediate in the production of HFC-365. The latter is useful as a nontoxic, zero ozone depleting fluorocarbon useful as a solvent, blowing agent, refrigerant, cleaning agent and aerosol to propellant.
摘要:
Provided are azeotrope-like compositions comprising tetrafluoropropene and hydrofluorocarbons and uses thereof, including use in refrigerant compositions, refrigeration systems, blowing agent compositions, and aerosol propellants.
摘要:
Provided are azeotrope-like compositions comprising heptafluoropropane and trifluoroiodomethane and uses thereof, including use in refrigerant compositions, refrigeration systems, blowing agents, fire suppressant compositions, and aerosol propellants.
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.
