一般的な説明
A water-white to pale-yellow liquid with an alcohol-like odor. About the same density as water. Flash point 170°F. Contact may irritate or cause burns.
-
空気と水の反応
Soluble in water. Reacts with water to form butanol and titanium dioxide, the reaction is not generally thought to be hazardous.
-
反応プロフィール
Organometallics are strongly reactive with many other groups. Incompatible with acids and bases. Organometallics are good reducing agents and therefore incompatible with oxidizing agents. Often reactive with water to generate toxic or flammable gases. Generally highly toxic. Often react on contact with tissues to give toxic products.

健康ハザード
LIQUID: Irritating to skin and eyes. If swallowed will cause nausea and vomiting.
-
火災危険
Combustible. Containers may explode in fire. May give off dense white smoke. Containers may explode.
-
安全性プロファイル
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.

純化方法
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.
