Title:
METHOD FOR PRODUCING PERFLUORO(2,4-DIMETHYL-2-FLUOROFORMYL-1,3-DIOXOLANE)
Document Type and Number:
WIPO Patent Application WO/2021/066155
Kind Code:
A1
Abstract:
Provided is a method for producing perfluoro(2,4-dimethyl-2-fluoroformyl-1,3-dioxolane), the method comprising a dimer reaction step for reacting, in an organic solvent, a trifluoropyruvate fluoride dimer and a hexafluoropropylene oxide in the presence of at least one fluoride selected from the group consisting of potassium fluoride and sodium fluoride to obtain perfluoro(dimethyl-2-oxo-1,4-dioxane).
