PREPARATIVE HAZARDS Titanium tetraiodide

Iodine and antimony powder react so violently as to cause ignition or explosion of the bulk of the mixture. A mixture of potassium and iodine explodes weakly on impact, while potassium ignites in contact with molten iodine [1], Interaction of molten iodine with titanium above 113°C under vacuum to form titanium tetraiodide is highly exothermic and sparks are produced. The preparative technique described permits the progressive reaction of 0.5 g portions of the titanium powder charged (7.2 g) to minimise hazard [2],...
