1.General Description: Appearance and odor vary depending upon the specific aluminum compound (NIOSH 1997). Generally, a colorless, pyrophoric liquid.
2.Air & Water Reactions :Highly flammable. Spontaneously flammable in air. Explodes violently in water [Rose 1961].
3.Reactivity Profile: Hydrides, such as Tri-N-propylaluminium, are reducing agents and react rapidly and dangerously with oxygen and with other oxidizing agents, even weak ones. Thus, they are likely to ignite on contact with alcohols. Hydrides are incompatible with acids, alcohols, amines, and aldehydes.
