Abstract
The present invention relates to a method for processing an aqueous solution containing a salt of an organic compound including at least one acid function and at least one fluorine atom, or fluoric acid, by reaction between said salt and at least one Bronsted acid and an alcohol in the presence of an organic solvent solubilizing the resulting product, wherein said organic solvent consists of at least one dual-phase liquid/liquid reaction medium with the aqueous solution.
Claims16
A process for treating an aqueous solution comprising a salt of an organic compound comprising at least one acid function and at least one fluorine atom, referred to as a fluoro acid, by reacting said salt in aqueous solution with at least one Bronsted acid and an alcohol selected from the group consisting of methanol, ethanol, and isopropanol in the presence of an organic solvent that dissolves the formed product, said organic solvent forming at least a liquid/liquid two-phase reaction medium with the aqueous solution, wherein the organic solvent is selected from the group consisting of aromatic solvents, chlorinated aliphatic solvents and alkyl ethers, and any mixture thereof.
