    Abstract: 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.
