使用
Triisobutylaluminium is a useful reagent for preparing anti-corrosive coating materials.
-
定義
A mixture of isomers
readily prepared by polymerizing isobutylene. A
typical mixture is 2,2,4,6,6-pentamethylheptane-
3 and 2-neopentyl-4,4-dimethylpentene-1. May be
depolymerized to simpler isobutylene derivatives.

空気と水の反応
Pyrophoric. Reacts violently with water producing flammable gas [Rose 1961].
-
反応プロフィール
Triisobutylaluminium reacts violently with alcohols, phenols, amines, carbon dioxide, sulfur oxides, nitrogen oxides, halogens, and halogenated hydrocarbons, causing fire and explosion hazards [Handling Chemicals Safely 1980. p. 937].
-
健康ハザード
Inhalation of smoke from fire causes metal-fume fever (flu-like symptoms). Contact with liquid can cause severe burns of eyes and skin because of spontaneous ignition.
-
火災危険
It is a highly pyrophoric compound, igniting
spontaneously in air. The flash point
is measured to be －18°C ( －1°F) (Aldrich
1996). A 1.0 M solution in hexane or toluene
is pyrophoric too. It decomposes explosively
with water. Reactions with lower alcohols,
halogenated hydrocarbons, halogens,
and common oxidizing substances can be
violent or explosive. Triisobutylaluminum is
thermally less stable than triethylaluminum,
decomposing above 50°C (122°F), producing
isobutene and hydrogen.
-
安全性プロファイル
A poison. Extremely
destructive to living tissue. A very dangerous
fire hazard; ignites on exposure to air.
Incompatible with moisture, acids, air,
alcohols, amines, halogens. To fight fire, use
CO2, dry sand, dry chemical. Do not use
water, foam, or halogenated extinguishing
agents. When heated to decomposition it
emits acrid smoke and irritating fumes.

職業ばく露
Alkyl aluminum compounds are used as components of olefin polymerization catalysts. They are also used in the synthesis of higher primary alcohols and in pyrophoric fuels, as a catalyst in making ethylene gas; and in plating aluminum.

不和合性
The lighter trialkylaluminums ignite spontaneously in air; can self-heat in the air at room temperature without any added energy and may ignite. These compounds are strong reducing agents. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Incompatible with water, oxygen (air), acids, alcohols, phenols, amines, carbon dioxide; sulfur oxides; halogenated compounds, and many other substances
