Abstract: The present disclosure provides a method for conversion of a mixture of high-boiling fluorinated components comprising 1,1,3,3-tetrachloro-1-fluoropropane (HCFC-241fa), 1,3,3-trichloro-1,1-difluoropropane (HCFC-242fa), 1,1,3-trichloro-1,3-difluoropropane (HCFC-242fb), 3,3-dichloro-1,1,1-trifluoropropane (HCFC-243fa), 1,3-dichloro-1,1,3-trifluoropropane (HCFC-243fb), 3-chloro-1,1,1,3-tetrafluoropropane (HCFC-244fa), their isomers, and combinations thereof, to 1-chloro-3,3,3-trifluoropropene (HCFO-1233zd). Heavy impurities, such as oligomers and other high boiling impurities, that are present may be purged during the process to prevent yield loss and reduction of catalyst efficacy.

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: Heterogenous azeotrope or azeotrope-like compositions comprising 3,3,3-trifluoropropyne (TFPY) and hydrogen fluoride (HF) which may include from about 71.5 wt. % to about 98.8 wt. % 3,3,3-trifluoropropyne (TFPY) and from about 1.2 wt. % to about 28.5 wt. % hydrogen fluoride and have a boiling point between about −10.0° C. and about 25.0° C. at a pressure of between about 61 psia and about 171 psia. The azeotrope or azeotrope-like compositions may be used to separate 3,3,3-trifluoropropyne (TFPY) as an impurity from compositions of 2-chloro-3,3,3-trifluoropropene (1233xf), 2-chloro-1,1,1,2-tetrafluoropropane (HCFC-244bb), or 2,3,3,3-tetrafluoropropene (HFO-1234yf).

Abstract: The present disclosure provides a process for producing trifluoroiodomethane, the process comprising providing a reactant stream comprising hydrogen iodide and at least one trifluoroacetyl halide selected from the group consisting of trifluoroacetyl chloride, trifluoroacetyl fluoride, trifluoroacetyl bromide, and combinations thereof, reacting the reactant stream in the presence of a first catalyst at a first reaction temperature from about 25° C. to about 400° C. to produce an intermediate product stream comprising trifluoroacetyl iodide, and reacting the intermediate product stream in the presence of a second catalyst at a second reaction temperature from about 200° C. to about 600° C. to produce a final product stream comprising the trifluoroiodomethane.

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.
