THALLIUM(III) FLUORIDE Chemical Properties,Usage,Production

Chemical Properties

olive green ortho-rhomb crystal(s); very sensitive to moisture; quickly decomposed by water; decomposed if heated in air [MER06] [KIR83]

Preparation

The fluorination of Thallium(III) fluoride Ti2Cl3 is accomplished in an apparatus consisting of a quartz reaction tube containing a quartz boat with the reagent. The fluorine gas is introduced via a 3-m.-long copper capillary which permits rotation of the reaction tube through a 90° angle. The reaction begins even at room temperature.
2T22O3+ 6F2 = 4TiF3 + 3O2
