Trioctylalumane

Trioctylalumane is an organoaluminum compound with the molecular formula C24H51Al and CAS number 1070-00-4. This chemical substance has a molecular weight of 366.6 g/mol and belongs to the family of trialkylaluminum compounds. It is characterized by three octyl groups bonded to a central aluminum atom, making it a highly reactive organometallic compound used in various industrial applications.

Trioctylalumane is typically a colorless to pale yellow liquid at room temperature with low volatility due to its high molecular weight. The compound is highly sensitive to moisture and air, readily reacting with water and oxygen. It is soluble in non-polar organic solvents such as hydrocarbons and ethers but reacts violently with polar protic solvents like water and alcohols.

Trioctylalumane is primarily used as a catalyst or co-catalyst in polymerization reactions, particularly in the production of polyolefins. It serves as an alkylating agent in organic synthesis and as a precursor for aluminum-containing thin films in semiconductor manufacturing. Additionally, it finds applications in the preparation of other organometallic compounds and as a reducing agent in specialized chemical processes.

Trioctylalumane must be handled under inert atmosphere conditions using appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work should be conducted in well-ventilated areas or under fume hoods due to its pyrophoric nature. Avoid contact with water, moisture, and oxidizing agents. Use only spark-free tools and equipment to prevent ignition of this highly reactive compound.

Trioctylalumane should be stored in tightly sealed containers under inert gas atmosphere (nitrogen or argon) to prevent contact with air and moisture. Storage areas must be cool, dry, and well-ventilated, away from heat sources, ignition sources, and incompatible materials such as water, alcohols, and oxidizing agents. Containers should be made of compatible materials and properly labeled according to safety regulations.

Trioctylalumane contact requires immediate action due to its reactive nature. In case of skin contact, remove contaminated clothing and flush the affected area with large amounts of water. For eye contact, rinse immediately with water for at least 15 minutes. If inhaled, move to fresh air immediately. Seek medical attention promptly in all cases and never use water on spills as it may cause violent reactions.

Trioctylalumane disposal must follow strict hazardous waste regulations due to its reactive and pyrophoric properties. The compound should be carefully neutralized by trained professionals using appropriate quenching agents under controlled conditions. Never dispose of it in regular waste streams or pour it down drains. Contact licensed hazardous waste disposal companies and follow local environmental regulations for proper disposal procedures.

Trioctylalumane is classified under ADR Class 4.2 (substances liable to spontaneous combustion) with Packing Group I, indicating high danger level. Transportation requires specialized packaging that prevents contact with air and moisture. Vehicles must be properly placarded and drivers trained in hazardous materials handling. Shipments must comply with international dangerous goods regulations and be accompanied by proper documentation and emergency response information.

Trioctylalumane is subject to various chemical safety regulations including REACH registration requirements in Europe and classification under the CLP Regulation. As an organometallic compound, it may be subject to specific handling and reporting requirements. While not currently listed as a SVHC substance, users must comply with occupational safety standards and environmental protection measures when handling this reactive chemical.
