liquid | [Hazard]
Strong irritant. | [Physical properties]
White cubic crystals or colorless volatile liquid; hygroscopic; density 2.54 g/cm3; melts at 17.5°C; boils at 34°C; critical temperature 200°C; critical pressure 46.88 atm; critical volume 226 cm3/mol; reacts with water (hydrolyzed). | [Definition]
ChEBI: Molybdenum hexafluoride is a molybdenum halide. | [Preparation]
Molybdenum hexafluoride is prepared by passing fluorine over molybdenum powder:
Mo + 3F2 → MoF6. | [Purification Methods]
Purify the hexafluoride by low-temperature trap-to-trap distillation over pre-dried NaF. It is hygroscopic, fumes in moist air and is hydrolysed readily by H2O. [Oppengard et al.
