The present disclosure provides a method for purifying trifluoroiodomethane. The method includes providing a process stream comprising trifluoroiodomethane, organic impurities, and acid impurities; reacting the process stream with a basic aqueous solution, the basic aqueous solution comprising water and at least one base selected from the group of an alkali metal carbonate and an alkali metal hydroxide; and separating at least some of the organic impurities from the process stream.

The present invention provides highly efficient processes for the preparation of chlorinated alkanes. The processes comprise contacting an alkene, halogenated alkene, or combinations thereof, a halogenated methane comprising at least one chlorine atom, at least one solid metallic catalyst, and a ligand forming a reaction mixture in a reactor. The product mixture does not contain a phase transfer catalyst. After a product mixture is formed, various fractions, distillation streams, and effluent streams are separated and/or treated with an aqueous alkaline substance. This treatment removes at least a portion of the metal and through recycling of the heavy fraction, treated product mixture, or combinations thereof, allows for the kinetics of the process to be maintained or increased.

The invention relates to a process comprising contacting a composition comprising a (hydro)halocarbon and a compound of formula R.sub.fCCX with a basic solution comprising an hydroxide, an alkoxide and/or an amide to reduce the concentration of R.sub.fCCX, wherein R.sub.f is a perfluorinated alkyl group and X is H, F, Cl, Br, or I. The invention further relates to process for preparing a (hydro)halocarbon comprising (i) converting a starting material, optionally in the presence of HF and/or a catalyst, to a composition comprising the (hydro)halocarbon and a compound of formula R.sub.fCCX, wherein R.sub.f is a perfluorinated alkyl group and X is H, F, Cl, Br, or I; (ii) contacting the composition with a basic solution comprising an hydroxide, an alkoxide and/or an amide to reduce the concentration of the compound of formula R.sub.fCCX; and (iii) recovering the (hydro)halocarbon.
