Production process of fluorine-containing carboxylic acid

The invention discloses a production process of fluorine-containing carboxylic acid. The method comprises the following steps: by taking fluorine-containing olefin as a raw material, carrying out an oxidation reaction to obtain fluorine-containing carboxylate, reacting the fluorine-containing carboxylate with an acylating chlorination reagent to obtain a corresponding mixture of fluorine-containing acyl chloride and fluorine-containing acid anhydride, and hydrolyzing and drying the mixture of fluorine-containing acyl chloride and fluorine-containing acid anhydride to prepare the high-purity fluorine-containing carboxylic acid. The method provided by the invention is suitable for post-treatment of fluorine-containing carboxylic acid prepared by a fluorine-containing olefin (monoolefine, diene, cycloolefin and the like) oxidation method, replaces the traditional strong acid acidification and ether continuous extraction process, and is simpler, more convenient and more applicable; the purity of the fluorine-containing carboxylic acid prepared by the method can reach 98% or above.

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.
