How Is Xenon Hexafluoride Synthesized?

Xenon hexafluoride (XeF6) can be synthesized by reacting xenon gas with excess fluorine gas in a sealed container at high temperature and pressure. The reaction typically occurs in the gas phase, and is exothermic and highly explosive.

The reaction proceeds as follows:

Xe(g) + 3F2(g) → XeF6(g)

The reaction is typically carried out using a mixture of xenon and fluorine gases in a ratio of approximately 1:5. The mixture is then heated to approximately 400-500°C while being subjected to high pressure (typically 10-20 atmospheres). Under these conditions, the xenon and fluorine react to form xenon hexafluoride.

The synthesis of xenon hexafluoride is a complex and hazardous process that requires careful handling and specialized equipment. Due to its high reactivity and potential for explosive decomposition, the compound must be handled with extreme caution.
