What is TIN(IV) IODIDE?
Chemical properties
Brown powder
The Uses of TIN(IV) IODIDE
Tin(IV) iodide is used in the preparation of tin(IV) oxide and tin(II) oxide. It reacts with hydroiodic acid to get rare tin hexaiodide. It forms tetraiodobis triphenylphosphine tin complexes by reacting with triphenylphosphine, which finds application in toothpaste formulation. Further, it acts as analytical reagents and also used in organic synthesis.
Safety Profile
Poison by intravenous route. Strong reaction with N02Cl, (K+ S), (Na + S). When heated to decomposition it emits toxic fumes of I-. See also TIN COMPOUNDS and IODIDES.
Purification Methods
It is recrystallised from anhydrous CHCl3, dry it under vacuum and store it in a vacuum desiccator. It sublimes at 180o.
