Preparation method of fluorine-containing binary acyl fluoride

The invention discloses a preparation method of fluorine-containing binary acyl fluoride. Fluorine-containing dicarboxylic acid as a raw material is subjected to fluorination with a fluorination reagent under the action of a solvent and a catalyst to obtain the fluorine-containing binary acyl fluoride. During actual production, the fluorine-containing dicarboxylic acid is directly fluorinated intocorresponding fluorine-containing diacyl fluoride under the action of the organic solvent and the Lewis acid catalyst, and the organic solvent and the specific catalyst are matched with other conditions, so that from the fluorine-containing dicarboxylic acid can be effectively promoted.

PROCESS FOR PRODUCING FLUORINATED COMPOUND

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.
