The Properties of Titanium Tetrachloride

Titanium tetrachloride has almost no oxidation at room temperature. Because Ti is more active, the tetravalent is relatively stable. However, at high temperature, titanium tetrachloride has certain oxidation. So, what is titanium tetrachloride? We will introduce it now!

Ⅰ. What is titanium tetrachloride

What is titanium tetrachloride used for? Titanium tetrachloride, also known as titanium chloride, is an inorganic compound with the chemical formula TiCl4 and a molecular weight of 189.68. And Ticl4 Cas No is 7550-45-0. It is an important titanium halide and an important raw material for the production of sponge titanium and titanium dioxide by chlorination.

Ⅱ. Properties of titanium tetrachloride

Titanium tetrachloride is a colorless and high-density liquid. If the sample is impure, it is often yellow or reddish brown. Similar to vanadium tetrachloride, it is one of the few transition metal chlorides that are liquid at room temperature. Its low melting boiling point is related to the weak intermolecular force. Most metal chlorides are polymers containing metal atoms connected by chlorine bridges, while the intermolecular force of titanium tetrachloride is mainly weak van der Waals force, so the melting boiling point is not high.

TiCl4 molecule has a tetrahedral structure, and each Ti4+ is connected with four ligands Cl-. Ti has the same electron number as the noble gas argon and is a closed shell structure. Therefore, titanium tetrachloride molecule is a tetrahedral structure with high symmetry. TiCl4 is soluble in non-polar toluene and chlorinated hydrocarbons. The results show that the dissolution of some aromatic hydrocarbons involves the formation of [(C6R6)TiCl3]+ complexes. Titanium tetrachloride can react exothermically with Lewis base solvent such as THF to form six coordinated adducts. For larger ligands, the product is five coordinated TiCl4L.

In addition to releasing corrosive hydrogen chloride, titanium oxide and chlorine oxide will be generated when storing TiCl4, which will stick to used plugs and syringes.

The above is some of the knowledge about titanium tetrachloride. I hope it will be helpful to you. If you want to know more about titanium tetrachloride, please feel free to contact us.
