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 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.

INTEGRATED CARBOXYLIC ACID PRODUCTION FROM SYNTHESIS GAS
A process for preparing C.sub.2 to C.sub.4 carboxylic acids from synthesis gas includes introducing a feed stream comprising hydrogen gas and a carbon-containing gas comprising carbon monoxide into a reaction zone of a first reactor, converting the feed stream into an intermediate stream comprising C.sub.2 to C.sub.4 hydrocarbons in the reaction zone in the presence of a first catalyst, wherein the intermediate stream further comprises carbon dioxide and wherein the first catalyst is a composite catalyst comprising a metal oxide catalyst component and a microporous catalyst component, and converting the intermediate stream into a product stream comprising C.sub.2 to C.sub.4 carboxylic acids in the presence of a second catalyst in a second reactor. The second reactor can be configured for olefin oxidation or paraffin oxidation.
