Provided is a method of producing perfluoro(2-methylene-4-methyl-1,3-dioxolane), the method including at least following processes (1) to (3): (1) reacting at least one of perfluoro(2,4-dimethyl-2-fluoroformyl-1,3-dioxolane) and a hydrolysis product there

METHOD FOR PRODUCING PERFLUORO (2,4-DIMETHYL-2-FLUOROFORMYL-1,3-DIOXOLANE)

PROBLEM TO BE SOLVED: To provide a production method which can produce a perfluoro (2,4-dimethyl-2-fluoroformyl-1,3-dioxolane) with a good yield while containing a trifluoropyruvic acid fluoride dimer and/or trifluoropyruvic acid fluoride as raw materials. SOLUTION: A method for producing perfluoro (2,4-dimethyl-2-fluoroformyl-1,3-dioxolane) includes: a reaction step of reacting at least one synthesis raw material selected from the group consisting of a trifluoropyruvic acid fluoride dimer and trifluoropyruvic acid fluoride with a hexafluoropropylene oxide in the presence of a fluoride in an organic solvent; a by-product decomposition step of decomposing a by-product in a reaction liquid obtained in the reaction step; and an isomerization step after the by-product decomposition step.
