Tris(2-methylpentyl)alumane

Tris(2-methylpentyl)alumane is an organoaluminum compound with the molecular formula C18H39Al and CAS number 3711-23-7. This chemical consists of an aluminum atom bonded to three 2-methylpentyl organic groups, giving it a molecular weight of 282.5 g/mol. As a member of the trialkylaluminum family, it exhibits typical characteristics of organometallic compounds, including high reactivity and pyrophoric properties that require careful handling in industrial applications.

Tris(2-methylpentyl)alumane is typically a colorless to pale yellow liquid at room temperature with high reactivity toward air and moisture. The compound has a molecular weight of 282.5 g/mol and is highly sensitive to oxidation due to its organometallic nature. It demonstrates typical trialkylaluminum properties including pyrophoric behavior, meaning it can spontaneously ignite upon contact with air, and reacts vigorously with water and alcohols to produce flammable gases.

Tris(2-methylpentyl)alumane is primarily used as a catalyst or co-catalyst in polymerization reactions, particularly in the production of polyolefins and other synthetic polymers. It serves as an alkylating agent in organic synthesis and can be employed in Ziegler-Natta catalysis systems. The compound is also utilized in semiconductor manufacturing processes and as a precursor for aluminum-containing thin films in chemical vapor deposition applications within the electronics industry.

Tris(2-methylpentyl)alumane must be handled under inert atmosphere conditions using appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and flame-resistant clothing. Work should be conducted in well-ventilated areas or under fume hoods to prevent exposure to vapors. Due to its pyrophoric nature, avoid contact with air, moisture, and ignition sources. Use specialized equipment designed for handling air-sensitive organometallic compounds and ensure proper grounding to prevent static electricity buildup.

Tris(2-methylpentyl)alumane must be stored under inert atmosphere in tightly sealed containers to prevent contact with air and moisture. Storage areas should be cool, dry, and well-ventilated, away from heat sources, oxidizing agents, and incompatible materials such as water, alcohols, and acids. The storage facility should be equipped with appropriate fire suppression systems and emergency response equipment. Containers should be properly labeled and stored in compliance with local regulations for pyrophoric materials.

In case of skin contact with tris(2-methylpentyl)alumane, immediately remove contaminated clothing and flush the affected area with large amounts of water for at least 15 minutes. For eye contact, rinse thoroughly with water and seek immediate medical attention. If inhaled, move the person to fresh air and provide respiratory support if needed. Due to the compound's reactive nature, do not use water directly on spills - instead, use dry sand or inert absorbent materials and contact emergency services immediately.

Tris(2-methylpentyl)alumane must be disposed of through specialized hazardous waste management facilities licensed to handle pyrophoric organometallic compounds. The material cannot be disposed of through normal waste streams due to its reactive properties. Small quantities can be carefully quenched with appropriate solvents under controlled conditions by trained personnel. All disposal activities must comply with local, national, and EU waste regulations, and proper documentation must be maintained throughout the disposal process.

Tris(2-methylpentyl)alumane is classified under ADR Class 4.2 (substances liable to spontaneous combustion) with Packing Group I, indicating high danger level. Transportation requires specialized packaging designed for pyrophoric materials, proper labeling with appropriate hazard symbols, and compliance with dangerous goods regulations. Shipments must be accompanied by proper documentation including safety data sheets and emergency response information. Only authorized carriers with expertise in handling pyrophoric chemicals should transport this material.

Tris(2-methylpentyl)alumane is subject to various chemical regulations including REACH registration requirements for import and use within the European Union. While not classified as an SVHC (Substance of Very High Concern), it falls under dangerous goods regulations due to its pyrophoric properties. Users must comply with workplace safety regulations, environmental protection laws, and transportation guidelines. Companies handling this material may need specific permits and must maintain appropriate safety management systems and emergency response procedures.

Tris(2-methylpentyl)alumane is available through OYSI, a specialized European distributor of technical chemicals with expertise in organometallic compounds. As a professional chemical supplier, OYSI provides this material to qualified industrial customers with proper handling capabilities and regulatory compliance. Due to the specialized nature and safety requirements of this compound, purchases typically require technical consultation to ensure appropriate handling, storage, and application protocols are in place at the customer's facility.
