摘要:
Provided are azeotropic and azeotrope-like compositions of trans-1,1,1,4,4,4-hexafluoro-2-butene (HFO-1336mzz(E)) and water. Such azeotropic and azeotrope-like compositions are useful in isolating HFO-1336mzz(E) from impurities during production. Azeotropes of the instant invention are similarly useful in final compositions, such as blowing agent, propellants, refrigerants, diluents for gaseous sterilization and the like.
摘要:
Provided are ternary azeotropic and azeotrope-like compositions of 2-chloro-3,3,3-trifluoropropene (HCFO-1233xf), 2-chloro-1,1,1,2-tetrafluoropropane (HCFC-244bb), 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:
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:
A fumigant composition including an azeotropic mixture of methyl iodide and sulfuryl fluoride; and a method of controlling at least one target insect species including treating a target space with a composition including an azeotropic mixture of methyl iodide and sulfuryl fluoride by applying an amount of the composition to the target space that is effective to kill a substantial portion of the target insect species in multiple development stages.

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:
An azeotropic or azeotrope-like composition comprising a mixture of methyl iodide, 1-chloro-3,3,3,-trifluoropropene, and optionally one or more of fluorocarbons and/or hydrofluorocarbons. 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.
摘要:
This invention provides azeotrope-like compositions of 1,1,1,3,3-pentafluoropropane and 2-chloropropane that are environmentally desirable for use as refrigerants, aerosol propellants, metered dose inhalers, blowing agents for polymer foam, heat transfer media, and gaseous dielectrics.
摘要:
A process for the preparation of a fluoroolefin polymer from an azeotropic mixture of monomers having a constant composition, the process including the step of: contacting in a reaction zone: (i) an initiator; and (ii) an azeotropic mixture of monomers including at least one fluoroolefin and, optionally, at least one ethylenically unsaturated comonomer capable of copolymerizing therewith; wherein the contacting is carried out at a temperature, pressure and length of time sufficient to produce the fluoroolefin polymer.
