TETRA N-BUTYL TITANATE(TNBT)

Air & Water Reactions

Soluble in water. Reacts with water to form butanol and titanium dioxide, the reaction is not generally thought to be hazardous.

Health Hazard

LIQUID: Irritating to skin and eyes. If swallowed will cause nausea and vomiting.

Fire Hazard

Combustible. Containers may explode in fire. May give off dense white smoke. Containers may explode.

Flammability and Explosibility

Flammable

Safety Profile

Suspected carcinogen. A poison by intravenous route. Moderately toxic by ingestion. See n-BUTYL ALCOHOL and TITANIUM COMPOUNDS. Flammable when exposed to heat or flame. To fight fire, use water, spray, foam, dry chemical. Incompatible with oxidizing materials. When heated to decomposition it emits acrid and irritating fumes.

Purification Methods

Dissolve it in *C6H6, filter if solid is present, evaporate and vacuum fractionate through a Widmer 24inch column (p 11). The ester hydrolyses when exposed to air to give hydrated ortho-titanic acid. The titanium content can be determined thus: weigh a sample (ca 0.25g) into a weighed crucible and cover it with 10mL of H2O and a few drops of conc HNO3. Heat (hot plate) carefully till most of the H2O has evaporated. Cool and add more H2O (10mL) and conc HNO3 (2mL), and evaporate carefully (no spillage) to dryness and ignite the residue at 600-650o/1hour. Weigh the residual TiO2. [Bradley et al.
