摘要:
The present invention provides azeotrope-like compositions of 1,1,1,2,2-pentafluoropropane (HFC-245cb) with either the Z isomer of 1,1,1,2,3-pentafluoropropene (HFO-1225yeZ) alone or with mixtures of the E and Z isomers of 1,1,1,2,3-pentafluoropropene (HFO-1225 yeZ and HFO-1225 yeE) and uses thereof, including use in refrigerant compositions, refrigeration systems, blowing agent compositions, and aerosol propellants, and in process for separating azeotrope-like mixtures.
摘要:
A method for the development or generation of pollution credits by the substitution of lower global warming potential (GWP) mixtures of halogenated hydrocarbons or mixtures of halogenated hydrocarbons with CO2 for fluorocarbons or fluorocarbon-containing compositions of higher GWP, such as for perfluorocarbon compounds (PFC's), hydrofluorocarbon compounds (HFC's), chlorofluorocarbons (CFC's), hydrochlorofluorocarbon compounds (HCFC's), and compositions thereof, in compositions and processes employing the higher GWP compounds, and receive allocation of pollution credits for such substitution.
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:
Compositions and methods based on the use of fluoroalkene containing from 3 to 4 carbon atoms and at least one carbon-carbon double bond, such as HFO-1214, HFO-HFO-1233, or HFO-1354, having properties highly beneficial in solvent cleaning applications.
摘要:
The use of pentafluoropropene (HFO-1225) and tetrafluoropropene (HFO-1234) in refrigeration equipment is disclosed. These materials are generally useful as refrigerants for heating and cooling, as blowing agents, as aerosol propellants, as solvent composition, and as fire extinguishing and suppressing agents.
