Chemical Properties

1 - Reactivity against Water
React with water strongly(hydrolysis) with large heat of reaction.
TiCl4+H2O → HCl+Ti(OH)nClx
2 - Reactivity against alcohol
React with alcohol to generate ester.
TiCl4+4ROH+4NH3 → Ti(OR)4+4NH4Cl
3 - Corrosion
Not corrosive against iron at room temperature, but corrosive at 200 degree C or more.
Generate corrosive HCl when reacted with water; to eliminate moisture in vessel and pipe.
