Titanium nitrate or titanium tetranitrate is the inorganic compound with formula Ti(NO3)4. It is an unusual example of a volatile binary transition metal nitrate.

Properties

Chemical

Titanium nitrate decomposes when heated, forming titanium dioxide and releasing nitrogen dioxide.

Ti(NO3)4 → TiO2 + 4 NO2

Anhydrous titanium nitrate is highly reactive, and will rapidly oxidize many organic compounds, such as n-dodecane, p-dichlorobenzene, anisole, biphenyl, as well as alkanes.

Physical

Titanium nitrate is a colorless volatile solid. It dissolves in water irreversibly forming hydrates. It is soluble in nonpolar solvents, such as carbon tetrachloride.

Availability

Titanium nitrate is sold by chemical suppliers as tetrahydrate. The anhydrous form does not appear to be available.

Preparation

Titanium nitrate can be prepared from the nitration of titanium(IV) chloride using dinitrogen pentoxide:

TiCl4 + 4 N2O5 → Ti(NO3)4 + 4 ClNO2

A hydrated titanium nitrate is produced upon dissolution of titanium metal or it compounds in nitric acid. The hydrated form cannot be converted into anhydrous, since the compound readily decomposes upon heating.

Projects

  • Oxidizing agent
  • Compound collecting

Handling

Safety

Titanium nitrate is a powerful oxidizer and harmful. Proper protection should be worn when handling the compound.

Storage

In dry airtight containers. Schlenck flasks, if available, can also be used.

Disposal

Should be dissolved into cooled water, then a base like sodium hydroxide should be added to precipitate the titanium dioxide.
