Titanium Tetra-iodide, TiI4

Titanium Tetra-iodide (Titanic Iodide), TiI4, is obtained when iodine vapour is passed over heated titanium, when hydrogen iodide is passed into titanium tetrachloride while the latter is gradually raised to its boiling-point, and by the action of iodine vapour and hydrogen on titanium tetrachloride at a dull red heat. Titanic iodide forms a reddish brown, brittle, metallic-looking mass which melts at 150° C., and then crystallises in large octahedra. It boils at 360° C., forming an orange vapour, and distils unchanged. Its vapour density at 440° C. is 18.054 (air = 1) or 260 (H = 1), indicating a molecular weight of 520, theory requiring 556. It fumes in the air, is combustible, and dissolves in water, forming a solution whence titanic acid soon separates by hydrolysis. Titanic acid dissolves in hydriodic acid, forming a deep red solution which probably contains hydriodotitanic acid; the acid and its salts are, however, too unstable to be isolated.
