SUMMARY
The discussion centers on the oxidation of hydrofluoric acid (HF) to fluorine gas (F2) using only chemical oxidizing agents, without the need for electrolytic cells or electric energy. Karl Christe's 1986 synthesis is highlighted, which involves the abstraction of two fluoride ions (F-) from manganese hexafluoride (MnF62-) using antimony pentafluoride (SbF5). This process leads to the formation of manganese tetrafluoride (MnF4), which is thermodynamically unstable and decomposes into stable manganese trifluoride (MnF3) and F2 gas.
