A method of manufacturing a trifluoropyruvyl fluoride dimer, comprising a reaction step of reacting hexafluoropropylene oxide and aldehyde.
An aldehyde adduct,
- wherein aldehyde is added to hexafluoropropylene oxide, the aldehyde adduct being prepared by reacting hexafluoropropylene oxide and aldehyde.
An aldehyde adduct, being at least one selected from the group consisting of the aldehyde adduct represented by Formula 1, the aldehyde adduct represented by Formula 2 and the aldehyde adduct represented by Formula 3,
- (where R in the Formulas 1, 2 and 3 represents a substituted or unsubstituted alkyl group or aryl) group.
