ABSTRACT:
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.
