Abstract
To provide a process for producing a desired perfluorinated product at a high yield in a fluorination reaction of a partially fluorinated ester.A perfluorinated compound (4) is obtained by fluorinating in a liquid phase a compound (3) (wherein the fluorine content is at least 30 mass %) obtained by reacting a compound (1) and a compound (2), wherein the compound (1) is HOCH2—RA—CH2OH, the compound (2) is X1C(═O)—C(RB)(RC)(RD), RA is a bivalent saturated hydrocarbon group or the like which has no hetero atom such as an etheric oxygen atom, X1 is a halogen atom, and —C(RB)(RC)(RD) is a branched group.
