Abstract
The process for producing a fluorine-containing compound such as 1,2,3,4-tetrachlorohexafluorobutane of the present invention is characterized in that a halogenated hydrocarbon compound such as 1,2,3,4-tetrachlorobutane is brought into contact with fluorine gas in a liquid phase or in a solid-liquid coexistence state in the absence of a solvent and a catalyst. According to the present invention, a fluorine-containing compound is readily produced from a halogenated hydrocarbon compound using neither a reaction solvent nor a reaction catalyst.
