Bis(2-methylpropyl)alumane

Bis(2-methylpropyl)alumane is an organoaluminum compound with the molecular formula C8H19Al and CAS number 1191-15-7. This chemical features aluminum bonded to two 2-methylpropyl groups, giving it a molecular weight of 142.22 g/mol. As an organoaluminum compound, it belongs to a class of chemicals known for their reactivity and utility in various industrial applications, particularly in catalysis and chemical synthesis processes.

Bis(2-methylpropyl)alumane is typically a colorless to pale yellow liquid at room temperature due to its organoaluminum structure. The compound is highly reactive with moisture and oxygen, making it air and water sensitive. It has a molecular weight of 142.22 g/mol and is generally soluble in non-protic organic solvents such as hydrocarbons and ethers, while being incompatible with protic solvents due to its reactive aluminum center.

Bis(2-methylpropyl)alumane 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 can be employed in the preparation of other organoaluminum compounds. The compound is also utilized in specialized chemical processes where controlled aluminum alkyl chemistry is required, including certain industrial synthesis applications and research activities.

Bis(2-methylpropyl)alumane 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 to prevent exposure to vapors. Due to its reactive nature, avoid contact with moisture, air, and incompatible materials. Use proper grounding procedures to prevent static discharge during transfer operations.

Bis(2-methylpropyl)alumane must be stored under inert gas atmosphere (nitrogen or argon) in tightly sealed containers to prevent contact with moisture and oxygen. Storage should occur in a cool, dry place away from heat sources and incompatible materials such as water, alcohols, and oxidizing agents. Containers should be made of compatible materials and stored in secondary containment systems to prevent environmental release in case of leakage.

Immediate removal from exposure is essential in case of contact with bis(2-methylpropyl)alumane. For skin contact, remove contaminated clothing and flush affected areas with plenty of water. In case of eye contact, rinse immediately with water for at least 15 minutes. If inhaled, move to fresh air immediately. Seek immediate medical attention for all exposure routes. Do not induce vomiting if ingested and contact poison control or emergency services immediately.

Bis(2-methylpropyl)alumane must be disposed of according to local, national, and international hazardous waste regulations. The compound should be neutralized carefully under controlled conditions before disposal, typically through controlled hydrolysis procedures. Contact certified hazardous waste disposal companies for proper treatment and disposal. Never discharge into drains, waterways, or soil. Maintain proper documentation of disposal procedures as required by applicable environmental regulations.

Bis(2-methylpropyl)alumane is classified under ADR Class 4.2 (Substances liable to spontaneous combustion), Packing Group I, indicating high danger level. Transport requires specialized packaging that prevents contact with moisture and air, typically under inert atmosphere. Proper shipping documentation, labeling, and placarding are mandatory. Only authorized carriers trained in handling dangerous goods should transport this material, following all applicable dangerous goods transportation regulations.

Bis(2-methylpropyl)alumane is subject to various chemical regulations including REACH registration requirements in the European Union for commercial use. It is not currently listed as a Substance of Very High Concern (SVHC). The compound must comply with CLP regulation requirements for classification and labeling, workplace safety regulations, and dangerous goods transport regulations. Users must ensure compliance with local chemical inventory and notification requirements.
