Tributylalumane

Tributylalumane is an organometallic compound with the chemical formula C12H27Al and CAS number 1116-70-7. This aluminum-based compound features three butyl groups attached to a central aluminum atom, giving it a molecular weight of 198.32 g/mol. It belongs to the family of organoaluminum compounds, which are characterized by direct aluminum-carbon bonds. Tributylalumane is primarily used in specialized industrial applications requiring organoaluminum chemistry, particularly in synthesis and catalytic processes where aluminum alkyl compounds are needed.

Tributylalumane is typically a colorless to pale yellow liquid at room temperature with a characteristic organometallic odor. As an organoaluminum compound, it is highly reactive with moisture and oxygen, making it air and water-sensitive. The compound is soluble in non-polar organic solvents such as hydrocarbons and ethers but reacts vigorously with protic solvents. Its molecular structure consists of three butyl chains attached to aluminum, giving it significant steric bulk and influencing its reactivity patterns in chemical processes.

Tributylalumane is used primarily as a reagent and catalyst in organic synthesis and polymer chemistry. It serves as an alkylating agent in the production of specialized chemicals and as a co-catalyst in polymerization reactions, particularly for olefin polymerization processes. The compound is also utilized in the synthesis of other organometallic compounds and as a reducing agent in certain chemical transformations. Its applications are typically found in research laboratories and specialized chemical manufacturing facilities requiring precise organoaluminum chemistry.

Tributylalumane 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 pyrophoric nature (ADR Class 4.2), avoid contact with air, moisture, and heat sources. Use dry, inert gas techniques and ensure all equipment is thoroughly dried before use. Emergency safety equipment including fire extinguishers suitable for metal fires should be readily available.

Tributylalumane 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, ignition sources, and incompatible materials such as water, alcohols, and oxidizing agents. Containers should be made of suitable materials like stainless steel or specially treated glass. Due to its ADR Class 4.2 classification as a spontaneously combustible substance, storage facilities must comply with regulations for pyrophoric materials and include appropriate fire suppression systems.

Tributylalumane exposure requires immediate action due to its reactive nature. For skin contact, immediately remove contaminated clothing and flush the affected area with large amounts of water, then seek medical attention. In case of eye contact, rinse immediately with plenty of water for at least 15 minutes and get medical help. If inhaled, move the person to fresh air and seek medical attention if symptoms occur. For ingestion, do not induce vomiting and seek immediate medical attention. Always inform medical personnel about the specific chemical involved.

Tributylalumane disposal must be conducted in accordance with local and national hazardous waste regulations due to its reactive and potentially dangerous nature. The compound should be carefully neutralized by qualified personnel using appropriate techniques for organoaluminum compounds, typically involving controlled hydrolysis under inert conditions. Disposal should only be performed by licensed hazardous waste disposal companies experienced in handling pyrophoric organometallic compounds. Empty containers must also be treated as hazardous waste and disposed of according to applicable regulations for spontaneously combustible materials.

Tributylalumane is classified under ADR Class 4.2 (spontaneously combustible substances), Packing Group I, indicating it presents a high danger during transport. Transportation requires specialized packaging designed for pyrophoric materials, with proper labeling and documentation according to dangerous goods regulations. Vehicles must be equipped with appropriate safety equipment and drivers must hold valid dangerous goods transport certificates. Shipments must comply with international transport regulations including ADR for road transport, and similar regulations for other transport modes. Professional logistics companies experienced in hazardous chemicals should handle transportation.

Tributylalumane is subject to various chemical regulations including REACH registration requirements for substances manufactured or imported in the European Union above certain tonnage thresholds. It is not currently listed as a Substance of Very High Concern (SVHC) under REACH. The compound must comply with CLP regulation for classification, labeling, and packaging, though specific GHS classifications may vary based on concentration and use. Additionally, its transport is regulated under ADR as a Class 4.2 dangerous good, and workplace handling is subject to occupational safety regulations in respective countries.
