Abstract: The present disclosure provides an integrated process for producing trifluoroiodomethane (CF3I), in three steps: a) reacting a first reactant stream comprising hydrogen (H2) and iodine (I2) in the presence of a first catalyst to produce a first product stream comprising hydrogen iodide (HI); (b) reacting the first product stream with a second reactant stream comprising trifluoroacetyl chloride (TFAC) in the presence of a second catalyst to produce an intermediate product stream comprising trifluoroacetyl iodide (TFAI); and (c) reacting the intermediate product stream to produce a final product stream comprising trifluoroiodomethane. (CF3I).

Abstract: A process for making 2,3,3,3-tetrafluoropropene (HFO-1234yf) includes providing a composition including 2-chloro-1,1,1,2-tetrafluoropropane (HCFC-244bb) to a reactor including a heater surface at a surface temperature greater than about 850° F. (454° C.), and then bringing the composition into contact with the heater surface for a contact time of less than 10 seconds to dehydrochlorinate a portion of the HCFC-244bb to make HFO-1234yf.

Abstract: The invention relates to a process to prepare tetrahalopropenes, such as 2-chloro-3,3,3-trifluoropropene (1233xf). The process comprises atomizing a feed material, such as 1,1,2,3-tetrachloropropene (1230xa) and the like, and mixing it with superheated HF to form a vaporized composition of feed material and HF with substantially instantaneous contact with a vapor phase fluorination catalyst. The invention extends catalyst life and forestalls catalyst deactivation.

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.
