Reactivity
TITANIUM TETRACHLORIDE acts as an acid in aqueous solution. During the reduction of TITANIUM TETRACHLORIDE to titanium metal with potassium, an explosion occurred. The system had been heated to 90 °C [Walter and Mandell 1967]. Addition directly to tetrahydrofuran caused a violent exothermic reaction [Inorg. Syn., 1982, 21, 135]. Ethylene can polymerize at low pressure if catalyzed by titanium halides. (Sundaram, K. M, M. M. Shreehan, E. F. Olszewski. "Ethylene." Kirk-Othmer Encyclopedia of Chemical Technology.

Safety Data Sheet
Getting an SDS for Titanium Tetrachloride
A Safety Data Sheet is written for a product, not for a substance: the supplier of the grade you actually buy issues it, so two suppliers of Titanium Tetrachloride issue two different sheets. That is why there is no single authoritative SDS for a substance to download — what there is, is the job of collecting the sheets for the products you hold and keeping them current as suppliers revise them.
