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.

摘要:
An azeotrope-like mixture consisting essentially of a binary azeotrope-like mixture consisting essentially of trans-1-chloro-3,3,3-trifluoropropene (trans-HFO-1233zd) and a second component selected from the group consisting of 2,3,3,3-tetrafluoropropene (HFO-1234yf) and trans-1,3,3,3-tetrafluoropropene (trans-HFO-1234ze), and combinations of these and various uses thereof.
摘要:
A composition including an effective amount of trans-1,3,3,3-tetrafluoropropene component combined with an effective amount of an alcohol selected from the group of methanol, ethanol, propanol, isopropanol, tert-butanol, isobutanol, 2-ethyl hexanol and any combination thereof, where the composition has azeotropic properties.
摘要:
Provided are azeotropic and azeotrope-like compositions of trans-1,3,3,3-tetrafluoropropene (HFO-1234ze(E)) and water. Such azeotropic and azeotrope-like compositions are useful in isolating trans-1,3,3,3-tetrafluoropropene from impurities during production. Azeotropes of the instant invention are similarly useful in final compositions or for the manufacture of final compositions, such as blowing agent, propellants, refrigerants, diluents for gaseous sterilization and the like.
摘要:
The present invention relates to an azeotropic or azeotrope-like mixture consisting essentially of 1,1,1,2,3,3-hexafluoropropane, hexafluoropropene and hydrogen fluoride.
摘要:
The invention pertains to azeotrope-like compositions of 1,1,2,3,3-pentafluoropropene (HFC-1225yc) and any one of 1,1,1,2-tetrafluoropropene (HFC-1234yf) or the Z-isomer of 1,1,1,2,3-pentafluoropropene (HFC-1225yeZ), and uses thereof, including use in refrigerant compositions, refrigeration systems, blowing agent compositions, and aerosol propellants.
