COBALT(III) FLUORIDE Chemical Properties,Usage,Production

Chemical Properties

brown powder

Chemical Properties

The heat of formation is —187 kcal mole-1 and the magnetic moment is 1-60 B.M. at 90°K rising to 2.46 B.M. at 293°K; it is thus a high spin compound but not magnetically dilute.
Anhydrous cobalt(III) fluoride turns dark in the presence of traces of water and reacts violently with the liquid-evolving oxygen. When heated in an inert atmosphere above 350°, cobalt(II) fluoride is formed. It reacts vigorously with many elements, e.g. Al, P, As, S, I, being reduced to cobalt(II) fluoride. It is insoluble in alcohol, ether and benzene and is a useful fluorinating agent in organic chemistry.

Physical properties

Light brown hexagonal crystal; density 3.88 g/cm³; moisture sensitive; stable in dry air; melts at 927°C; reacts with water.

Uses

Important fluorinating agent, particularly for complete fluorination of hydrocarbons by the Fowler process.

Uses

Cobalt(III) fluoride is a powerful fluorinating agent.

Preparation

Cobalt(III) fluoride may be prepared by reaction of elemental fluorine with cobalt(II) fluoride, cobalt(II) chloride or cobalt(III) oxide at 300 to 400°C.
2CoF₂ + F₂ → 2CoF₃
2CoCl₂ + 3F₂ → 2CoF₃ + 2Cl₂
It should be stored in a sealed glass ampule, free from moisture.
Electrolytic oxidation of cobalt(II) fluoride in 40% hydrofluoric acid yields hydrated cobalt(III) fluoride, CoF₃·3.5H₂O (3.5 is the stoichiometric amount of water per CoF3 molecule in the crystal lattice).

Hazard

Strong irritant to tissue.

Structure and conformation

It forms hexagonal crystals of density 3.89, isomorphous with iron(III) and aluminium(III) fluorides, the cobalt atoms being octahedraily surrounded by fluorine atoms.
