titanium trichloride (7705-07-9)

1.General Description: A dark violet crystalline solid. Denser than water. Contact may burn skin, eyes, and mucous membranes. May be toxic by ingestion, inhalation and skin absorption. Used to make other chemicals.
2.Air & Water Reactions :Pyrophoric, very reactive with water and moisture in air produces hydrochloric acid,  Ignites spontaneously on contact with air; decomposed by water and water vapor forming HCl. Reactivity Profile Acidic salts, such as Titanium chloride (CAS NO.7705-07-9) , are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions. Ethylene can polymerize at low pressure if catalyzed by titanium halides.
4.Health Hazard Fire will produce irritating, corrosive and/or toxic gases. Inhalation of decomposition products may cause severe injury or death. Contact with substance may cause severe burns to skin and eyes. Runoff from fire control may cause pollution.
5.Fire Hazard Flammable/combustible material. May ignite on contact with moist air or moisture. May burn rapidly with flare-burning effect. Some react vigorously or explosively on contact with water. Some may decompose explosively when heated or involved in a fire. May re-ignite after fire is extinguished. Runoff may create fire or explosion hazard. Containers may explode when heated.
