| | TRI-N-PROPYLALUMINIUM Usage And Synthesis |
| Chemical Properties | The aluminum alkyls are highly flammable and reactive, colorless to yellow liquids at room temperature. The lighter trialkylaluminums ignite spontaneously in air. They are normally supplied and used in a 20% solution with a hydrocarbon solvent, such as hexane, heptane, benzene, toluene. Properties may depend on solvent. Reacts violently with water. | | Chemical Properties | clear colorless liquid | | General Description | Appearance and odor vary depending upon the specific aluminum compound (NIOSH 1997). Generally, a colorless, pyrophoric liquid. | | Air & Water Reactions | Highly flammable. Spontaneously flammable in air. Explodes violently in water [Rose 1961]. | | 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. | | Safety Profile | Pyrophoric, moisturesensitive,
flammable solid. Danger from
spontaneous combustion. When heated to
decomposition it emits toxic fumes of Al. | | Potential Exposure | 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. | | Shipping | ntial fire or explosion hazard. Shipping: UN3399 Organometallic substance, liquid, water-reactive, flammable, Hazard Class: 4.3; Labels: 4.3
Dangerous Dangerous when wet material, 3-Flammable liquid, technical name Required. UN3051-Spontaneously combustible. Also, this material is dangerous when wet. (Note: this number does not appear in the 49/CFR HazMat tables). | | Incompatibilities | 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 | | Waste Disposal | Careful incineration |
