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.
一种含氟的多价羰基化合物通过一种经济优势的方法从廉价原料中生产而来,无需复杂的合成过程步骤。具体而言,本发明包括将至少具有一种主要醇,次要醇和三级醇中选择的两种醇骨架的多价醇与酸卤反应以获得多价酯化合物,将其在液相中氟化以获得全氟多价酯化合物,并断裂由主要和次要醇衍生的酯键以获得含氟的多价羰基化合物。
