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.

Processes for producing trifluoroiodomethane and trifluoroacetyl iodide

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&#xb0; C. to about 400&#xb0; 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&#xb0; C. to about 600&#xb0; C. to produce a final product stream comprising the trifluoroiodomethane.

The present invention relates to a process for the preparation of haloethylenes, and preferably perhaloethylenes, by the gas-phase dechlorination of haloethanes in the presence of a catalyst and optionally in the presence of an alkene or an alkane. In particular aspects, the invention relates to a gas-phase process for preparing chlorotrifluoroethylene (CTFE). More particularly, the present invention relates to a gas-phase process for preparing CTFE from 1,1,2-trichloro-1,2,2-trifluoroethane (CFC-113) by dechlorination in the presence of an alkene or an alkane and a catalyst.

Gas phase process for chlorotrifluoroethylene

The production of 1, 1, 2-trifluoro-2-(trifluoromethyl)cyclobutane (TFMCB). More specifically, the present invention relates to a process for making 1, 1, 2-trifluoro-2-(trifluoromethyl)cyclobutane via a continuous catalytic reaction from commercially available raw materials ethylene and hexafluoropropene.

Process for the production of fluorinated cyclobutane

The production of 1,1,2-trifluoro-2-(trifluoromethyl)cyclobutane (TFMCB). More specifically, the present invention relates to a process for making 1,1,2-trifluoro-2-(trifluoromethyl)cyclobutane via a continuous catalytic reaction from commercially available raw materials ethylene and hexafluoropropene.

Disclosed is a one step process for making of 1,1,1,4,4,4-hexafluoro-2-butene. More specifically, the present invention provides a process for making hexafluoro-2-butene, continuously, from 2-chloro-3,3,3-trifluoropronene using FeO/NiO impregnated carbon catalyst at 600&#xb0; to 650&#xb0; C.
