Preparation method of fluorine-containing dicarboxylic acid

The invention discloses a preparation method of fluorine-containing dicarboxylic acid, which comprises: by using fluorine-containing cycloolefin as a raw material, performing oxidation with an oxidantunder the actions of a solvent and a catalyst to generate the corresponding fluorine-containing dicarboxylic acid. According to the method, a mixed solvent composed of the organic solvent and water is used as a solvent system of an oxidation reaction, the fluorine-containing cycloolefin is oxidized into corresponding fluorine-containing dicarboxylic acid by using the oxidant under the action of the catalyst, and the method has the characteristics of simple operation, stable process, safety, short reaction time, high yield and high product quality, and is suitable for large-scale production.

METHODS OF MAKING POLYFUNCTIONAL POLYFLUORINATED COMPOUNDS

A method of making a polyfunctional polyfluorinated compound includes combining first components that include a polyfluorinated cyclic compound having 4 to 7 ring carbon atoms and at least one of osmium tetroxide, ruthenium tetroxide or a precursor thereof and forming a polyfluorinated dicarboxylic acid. Two of the ring carbon atoms of the polyfluorinated cyclic compound form a double bond or an epoxide. The precursor reacts with an oxidant to form ruthenium tetroxide. Methods also include converting the polyfluorinated dicarboxylic acid to a polyfluorinated dicarboxylic acid halide and converting the polyfluorinated dicarboxylic acid halide to other polyfunctional polyfluorinated compounds.
