Tris(2-methylpropyl)alumane

Tris(2-methylpropyl)alumane is an organoaluminium compound with the molecular formula C12H27Al and CAS number 100-99-2. This chemical consists of an aluminum atom bonded to three 2-methylpropyl groups (isobutyl groups). With a molecular weight of 198.32 g/mol, it belongs to the class of trialkylaluminium compounds which are typically used as catalysts and reagents in organic synthesis and industrial processes.

Tris(2-methylpropyl)alumane is typically a colorless to pale yellow liquid at room temperature with a characteristic organometallic odor. As an organoaluminium compound, it is highly reactive with moisture and oxygen, leading to spontaneous combustion in air. It is soluble in hydrocarbon solvents and ethers but reacts violently with water and alcohols, producing flammable gases and heat.

Tris(2-methylpropyl)alumane is primarily used as a catalyst and co-catalyst in polymerization reactions, particularly in the production of polyolefins. It serves as an alkylating agent in organic synthesis and is employed in the semiconductor industry for chemical vapor deposition processes. Additionally, it finds applications in the production of specialty chemicals and as a reducing agent in various industrial chemical processes.

Tris(2-methylpropyl)alumane must be handled under inert atmosphere conditions to prevent contact with air and moisture. Essential protective equipment includes chemical-resistant gloves, safety goggles, and flame-resistant clothing. Work should be conducted in well-ventilated areas or under fume hoods, away from ignition sources. Personnel must be trained in pyrophoric material handling procedures and emergency response protocols.

Tris(2-methylpropyl)alumane must be stored under inert gas atmosphere in tightly sealed containers to prevent contact with air and moisture. Storage areas should be cool, dry, and away from heat sources and incompatible materials such as water, alcohols, and oxidizers. Containers should be made of suitable materials like stainless steel or specially treated glass, with proper labeling and emergency equipment nearby.

Skin contact with tris(2-methylpropyl)alumane requires immediate removal of contaminated clothing and thorough irrigation with mineral oil or petroleum jelly, never water. For eye contact, flush immediately with mineral oil and seek medical attention. In case of inhalation, move to fresh air and provide oxygen if needed. For ingestion, do not induce vomiting and seek immediate medical care while providing supportive treatment.

Tris(2-methylpropyl)alumane disposal must be conducted by licensed hazardous waste contractors following local and EU regulations. The compound should be carefully quenched with suitable alcohols under controlled conditions before disposal. Containers must be properly labeled and transported according to dangerous goods regulations. Never dispose of this material in regular waste streams or pour down drains due to its reactive nature.

Tris(2-methylpropyl)alumane is classified under ADR Class 4.2 (spontaneously combustible substances), Packing Group I, indicating high danger level. Transport requires specialized packaging that prevents contact with air and moisture, proper labeling with hazard diamonds, and compliance with dangerous goods regulations. Vehicles must be equipped with appropriate safety equipment and drivers must hold valid dangerous goods certificates.

Tris(2-methylpropyl)alumane is subject to REACH registration requirements in the European Union and must comply with CLP classification and labeling regulations. While not currently listed as an SVHC substance, it falls under strict handling and transport regulations due to its pyrophoric nature. Companies must maintain safety data sheets, implement appropriate risk management measures, and ensure worker training compliance.

Tris(2-methylpropyl)alumane is available through specialized chemical distributors like OYSI, which serves the European market with technical-grade chemicals. Due to its hazardous nature and specialized applications, this compound is typically sold to qualified industrial customers with appropriate handling facilities. Buyers must demonstrate proper storage capabilities and regulatory compliance before purchase approval.
