    摘要: Provided are azeotropic and azeotrope-like compositions of 1,2,3,3,3-pentafluoropropene (HFO-1225ye) and water. Such azeotropic and azeotrope-like compositions are useful in isolating 1,2,3,3,3-pentafluoropropene from impurities during production. Azeotropes of the instant invention are similarly useful in final compositions or manufacturing final compositions, such as blowing agent, propellants, refrigerants, diluents for gaseous sterilization and the like.

    摘要: Azeotropic or azeotrope-like compositions of the present technology include methyl chloride and at least one hydrofluorocarbon or hydrofluoro-olefin. In some examples, the at least one hydrofluorocarbon or hydrofluoro-olefin can be selected from the group consisting of 1,1,1,2-tetrafluoroethane and 1,3,3,3-tetrafluoropropene. The azeotropic or azeotrope-like compositions can be used as solvents or diluents in polymerization processes, including slurry polymerization processes.
