Trioctylalumane

Trioctylalumane is an organoaluminum compound with the molecular formula C24H51Al and CAS number 1070-00-4. This chemical substance consists of an aluminum atom bonded to three octyl groups, giving it a molecular weight of 366.6 g/mol. As a specialized organometallic compound, trioctylalumane belongs to the family of alkylaluminum chemicals used in various industrial applications requiring aluminum-carbon bonding properties.

Trioctylalumane is typically a colorless to pale yellow liquid at room temperature due to its long alkyl chain structure. The compound exhibits low solubility in water but shows good solubility in organic solvents such as hydrocarbons and ethers. Its high molecular weight (366.6 g/mol) and branched structure contribute to its relatively high boiling point and viscosity compared to simpler alkylaluminum compounds.

Trioctylalumane is primarily used as a catalyst or co-catalyst in polymerization reactions, particularly in the production of polyolefins. It serves as an activator in metallocene catalysis systems and finds applications in alkylation reactions. The compound is also utilized in the synthesis of other organometallic compounds and as a reducing agent in specialized chemical processes within the petrochemical and polymer industries.

Trioctylalumane requires careful handling due to its classification as ADR Class 4.2 (spontaneously combustible substances). Personnel should wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work should be conducted in well-ventilated areas or under inert atmosphere to prevent contact with air and moisture. Keep away from heat sources, open flames, and oxidizing materials during handling operations.

Trioctylalumane must be stored under inert gas atmosphere (nitrogen or argon) in tightly sealed containers to prevent oxidation and spontaneous combustion. Storage areas should be cool, dry, and well-ventilated, away from heat sources and incompatible materials such as water, alcohols, and oxidizing agents. Containers should be made of compatible materials and properly labeled according to ADR Class 4.2 requirements.

Trioctylalumane contact requires immediate action due to its reactive nature. For skin contact, remove contaminated clothing and flush the affected area with plenty of water for at least 15 minutes. In case of eye contact, rinse immediately with water and seek medical attention. If inhaled, move the person to fresh air and provide respiratory support if needed. Never use water directly on spilled material due to potential violent reactions.

Trioctylalumane disposal must comply with local and national hazardous waste regulations as it is classified as dangerous goods. The compound should be carefully neutralized using appropriate methods under controlled conditions, typically involving reaction with alcohols or water under inert atmosphere. Contact licensed hazardous waste disposal companies for proper treatment and disposal. Never dispose of untreated material in regular waste streams or sewage systems.

Trioctylalumane is classified under ADR Class 4.2 (spontaneously combustible substances) Packing Group I, indicating high danger level during transport. Packages must comply with specific UN packaging requirements and be properly labeled with appropriate hazard labels. Transport vehicles must carry appropriate documentation and emergency response information. Only trained personnel should handle transportation, and specific routing restrictions may apply depending on local regulations.

Trioctylalumane is subject to REACH regulation as a chemical substance placed on the European market, requiring registration for quantities above specified thresholds. The compound must comply with CLP regulation for classification and labeling requirements. As it is not listed as a SVHC (Substance of Very High Concern), standard registration procedures apply. Users must maintain safety data sheets and comply with occupational exposure limits where applicable.
