Tris-decylalumane

Tris-decylalumane is an organoaluminum compound with the molecular formula C30H63Al and CAS number 1726-66-5. This chemical consists of an aluminum atom bonded to three decyl groups (C10H21), making it a trialkylaluminum compound with a molecular weight of 450.8 g/mol. It belongs to the family of organometallic compounds and is characterized by its high reactivity due to the aluminum-carbon bonds.

Tris-decylalumane is typically a colorless to pale yellow liquid at room temperature with low volatility due to its high molecular weight of 450.8 g/mol. As an organoaluminum compound, it is highly sensitive to moisture and air, reacting vigorously with water and alcohols. It is soluble in non-polar organic solvents such as hydrocarbons and ethers but must be handled under inert atmosphere conditions.

Tris-decylalumane 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. Additionally, it finds applications in the preparation of other organometallic compounds and as a reducing agent in specialized chemical processes.

Tris-decylalumane must be handled under strict 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 pyrophoric nature (ADR class 4.2), avoid contact with air, moisture, and oxidizing materials. Always use proper transfer techniques and inert gas protection.

Tris-decylalumane must be stored under inert atmosphere (nitrogen or argon) in tightly sealed containers to prevent contact with moisture and air. Storage areas should be cool, dry, and well-ventilated, away from heat sources, oxidizing agents, and incompatible materials. As a Group I dangerous good (ADR 4.2), it requires specialized storage conditions with appropriate fire prevention measures and emergency response equipment readily available.

Tris-decylalumane contact requires immediate action due to its reactive nature. For skin contact, do not use water - instead brush off any solid material and seek immediate medical attention. In case of eye contact, flush with mineral oil (never water) and get emergency medical care. If inhaled, move to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical attention while providing safety data sheet to medical personnel.

Tris-decylalumane disposal must comply with local and national hazardous waste regulations due to its reactive and pyrophoric properties. Small quantities should be carefully quenched with suitable solvents under controlled conditions by trained personnel. Larger quantities require professional hazardous waste disposal services. Never dispose of in regular waste streams or pour down drains. Contact specialized chemical waste disposal companies for safe destruction and regulatory compliance.

Tris-decylalumane is classified under ADR as Class 4.2 (substances liable to spontaneous combustion), Packing Group I, indicating high danger level. Transportation requires specialized packaging meeting UN specifications, proper labeling with hazard placards, and compliance with dangerous goods regulations. Shipments must be accompanied by proper documentation including safety data sheets and emergency response information. Only certified dangerous goods carriers should handle transportation.

Tris-decylalumane is subject to various chemical regulations including REACH registration requirements in Europe for manufacture, import, and use above threshold quantities. While not currently listed as a SVHC (Substance of Very High Concern), it must comply with CLP regulation for classification and labeling. Additional workplace safety regulations apply due to its hazardous properties, and environmental regulations govern its disposal and emissions.
