  • Azeotropes of methyl chloride with fluorocarbons
    Patent number: 8592538
    Abstract: 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.
    Type: Grant

  • Purification of trans-1,3,3,3-tetrafluoropropene
    Patent number: 8337595
    Abstract: Disclosed is a process for removing impurities from a product stream comprising trans HFO-1234ze and an HFO-1234 impurity that uses one or more adsorbents that are selective for the HFO-1234 impurity, such that the HFO-1234 impurity is removed from the product stream. One such impurity is HFO-1234zc, which is removed from its mixture with trans HFO-1234ze by action of an adsorbent having pores in the range of from about 5 angstroms to about 10 angstroms.
