Abstract: A method of producing trifluoroiodomethane (CF3I) includes providing a feedstock comprising trifluoroacetyl iodide (TFAI), passing the feedstock through at least one column charged with carbonaceous materials to remove hydrogen iodide (HI), hydrogen triiodide (HI3) and iodine (I2) from the feedstock, and providing the feedstock to a reactor to produce a trifluoroiodomethane product stream.
Another method of producing trifluoroiodomethane (CF3I) includes providing a feedstock comprising trifluoroacetyl iodide (TFAI) to a reactor to produce a trifluoroiodomethane product stream, and passing the trifluoroiodomethane product stream from the reactor through at least one column charged with carbonaceous materials to remove hydrogen iodide (HI), hydrogen triiodide (HI3) and iodine (I2) from the trifluoroiodomethane product stream.

Abstract: Impurities such as sulfur dioxide (SO2) are removed from trifluoroacetyl chloride (TFAC) through distillation, adsorption, or a combination thereof, and/or including the formation of an azeotrope or azeotrope-like composition including effective amounts of sulfur dioxide (SO2) and trifluoroacetyl chloride (TFAC). The trifluoroacetyl chloride (TFAC) thus purified may then be used in the manufacture of trifluoroiodomethane (CF3I). Also disclosed are azeotropes and azeotrope like compositions of sulfur dioxide (SO2) and trifluoroacetyl chloride (TFAC).

Abstract: The present invention relates, in part, to an alpha-alumina support for a hydrogenation catalyst useful in hydrogenating fluoroolefins. In certain aspects, it relates to a method for hydrogenating a compound by contacting an olefin reactant having at least one carbon-fluorine bond, with a supported hydrogenation catalyst. The reaction results in a product that includes a hydrogenated derivative of the olefin. In certain embodiments, the supported hydrogenation catalyst includes a zero-valent metal disposed on an alpha-alumina support.
