    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: Processes for the preparation and purification of hydrofluoroolefins such as tetrafluorinated propenes. A process is provided for separating a first hydrofluoroolefin from a second hydrofluoroolefin by a) providing a mixture including a first hydrofluoroolefin and a second hydrofluoroolefin, which first hydrofluoroolefin is preferentially more reactive with an amine than the second hydrofluoroolefin; b) adding a sufficient amount of an amine to the mixture to form a combination including the second hydrofluoroolefin and a reaction product of the first hydrofluoroolefin and the amine; and then c) separating the reaction product from the combination. This is particularly useful for removing 1,2,3,3,3-pentafluoropropene (HFO-1225ye) impurities from the hydrofluoroolefin 2,3,3,3-tetrafluoropropene (HFO-1234yf). HFO-1234yf is a refrigerant with low global warming potential.
