Quick Summary

Titanium trichloride (TiCl₃) is a compound of titanium that exhibits the +3 oxidation state. It is a crystalline substance that serves as a catalyst in the stereospecific polymerization of propylene, a process crucial for producing polypropylene, a commercially valuable polymer.1

Titanium, the element, is a lightweight, corrosion-resistant metal known for its high strength-to-weight ratio. It is widely distributed in Earth's crust and is found in various minerals, primarily ilmenite and rutile. The production of titanium metal often involves the reduction of titanium tetrachloride (TiCl₄). Titanium tetrachloride itself is a volatile liquid compound used in applications like skywriting and smoke screens due to its fuming in moist air.123
