Title:
METHOD FOR PRODUCING FLUOROESTER COMPOUND
Document Type and Number:
WIPO Patent Application WO/2024/111485
Kind Code:
A1
Abstract:
A method for producing a fluoroester compound, which includes fluorinating an ester compound having at least one atom or bond capable of being fluorinated, in an organic solvent having fluorine gas introduced thereinto, wherein the organic solvent contains a compound having a C-H bond, the amount of the compound having a C-H bond being at least 0.1 time by mass the amount of the ester compound having at least one atom or bond capable of being fluorinated.
