摘要:
A fluorinated polyvalent carbonyl compound is produced by an economically advantageous method from inexpensive materials without requiring a complicated synthetic process step. Namely, the present invention comprises reacting a polyvalent alcohol having at least two kinds of alcohol skeletons selected among a primary alcohol, a secondary alcohol and a tertiary alcohol, with an acid halide to obtain a polyvalent ester compound, fluorinating it in a liquid phase to obtain a perfluorinated polyvalent ester compound, and cleaving the ester bonds derived from primary and secondary alcohols in the perfluoropolyvalent ester compound to obtain a fluorinated polyvalent carbonyl compound.
