Abstract: In this method, RH2ORH1SO2F is added to hydrofluoric acid so as to form a thick solution (hydrogen bonded complex), and the solution is directly supplied to a liquid phase reaction system, in which an F2 gas is used. Alternatively, RH2ORH1SO2Cl is added to hydrofluoric acid so as no be converted into RH1ORH2SO2F by disc barging HCl, and the RH1ORH2SO2F is directly supplied to a liquid phase reaction system in which an F2 gas is used. Consequently, fluorination can be carried out safely and a compound having an objective structure can be produced at low cost without causing isomerization or the like.

Abstract: This process for producing fluorine-containing compounds includes liquid-phase fluorination by introducing a raw material compound and fluorine gas into a solvent to replace hydrogen atoms in the raw material compound with fluorine atoms. More specifically, the process for producing fluorine-containing compounds includes (1) promoting fluorination by dissolving the raw material compound in anhydrous hydrofluoric acid and introducing into a liquid-phase fluorination solvent, or (2) promoting fluorination by dissolving the raw material compound in a perfluoro compound having a plurality of polar groups in a molecule thereof and introducing into a liquid-phase fluorination solvent. According to these processes, a fluorination reaction can be carried out at high yield and without containing hardly any isomers while using a hydrocarbon compound as is for the raw material.

Abstract: Divalent and trivalent metal salts are added to the solution containing the fluorine compound to precipitate the layered double hydroxide containing the fluorine compound between layers. By these processes, the fluorine compound can be fixed with high rate. Moreover, if necessary, the precipitated layered double hydroxide can be recovered to separate the fluorine compound or its salt between layers. Therefore, the burden to environment or the ecosystem by the fluorine compound can be reduced.

Abstract: Divalent and trivalent metal salts are added to the solution containing the fluorine compound and the polymer containing fluorine to precipitate the layered double hydroxide containing the fluorine compound between layers. At this time, the polymer containing fluorine suspended in the solution is also coagulated to precipitate. By these processes, the fluorine compound is fixed with high rate to separate from the solution with the polymer containing fluorine, and recovered if necessary. By this treatment process, the fluorine compound and the polymer containing fluorine, contained in the wastewater etc. can be separated easily, and the burden to environment or ecosystem can be reduced.
