Preparation method of fluorine-containing binary acyl fluoride
-
Paragraph 0038-0041; 0046, (2020/07/12)
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.

Paragraph 0433; 0434; 0435, (2016/12/22)
Provided is a method for producing a desired perfluorinated product with high yield by a fluorination reaction of a partially fluorinated ester. A compound (3), which is produced by reacting a compound (1) with a compound (2) (and which has a fluorine content of 30 mass% or more), is fluorinated in a liquid phase to produce a perfluorinated compound (4), wherein the compound (1) is represented by the formula HOCH2-RA-CH2OH and the compound (2) is represented by the formula X1C(=O)-C(RB)(RC)(RD). RA represents a bivalent saturated hydrocarbon group or the like and does not have a hetero atom such as an ethereal oxygen atom. X1 represents a halogen atom, and -C(RB)(RC)(RD) represents a branched group.
