Definitions
- fluorine or a fluorine-containing compound is synthesized by an electrolytical synthesis method.
- the method comprising conducting electrolysis using the electrode for electrolysis according to the present invention in an electrolytic bath comprising hydrofluoric acid and, added thereto, a substance to be fluorinated, is preferable.
- the electrolysis was stopped and the anode was taken out. As a result, the anode was found to have broken into powder in the electrolyzer.
- This electrode was attached to a (CH 3 ) 4 NF ⁇ 5HF electrolytic bath immediately after preparation of the bath.
- a nickel plate and Cu/CuF 2 were used as a cathode and a reference electrode, respectively, and constant-current electrolysis was conducted at a current density of 100 mA/cm 2 .
- the anode potential was measured and was found to be 4.6 V.
- the anode potential was 4.8 V.
- the electrolysis was stopped, and the anode was taken out and examined for contact angle between a surface of the electrode and water. As a result, the contact angle was found to be 150 degrees. It was hence ascertained that the so-called anode effect had occurred.
- Electrolysis was conducted in a (CH 3 ) 4 NF ⁇ 5HF electrolytic bath immediately after preparation of the bath, in the same manner as in Example 2 except that the electrode produced was used as an anode.
