Overview

Tridodecylalumane (CAS 1529-59-5) is an organoaluminum compound featuring three long-chain dodecyl groups attached to a central aluminum atom. This specialized organoaluminum compound belongs to the trialkylaluminum family, characterized by its unique molecular structure consisting of an aluminum center bonded to three dodecyl chains (C12H25). With a molecular formula of C36H75Al and molecular weight of 535 g/mol, tridodecylalumane represents one of the higher molecular weight members in this chemical class. The compound is classified under ADR Class 4.2, indicating its pyrophoric nature and potential for spontaneous ignition when exposed to air. The extended dodecyl chains provide tridodecylalumane with distinctive properties compared to shorter-chain analogs like tripropylalumane or trioctylalumane, particularly in terms of solubility characteristics and thermal behavior. This organoaluminum compound exhibits typical reactivity patterns associated with aluminum-carbon bonds, making it highly moisture-sensitive and requiring careful handling under inert atmosphere conditions. In industrial applications, tridodecylalumane serves primarily as a specialized catalyst component in polymerization processes, particularly in the production of polyolefins where its unique chain length can influence polymer characteristics. The compound also finds use as a cocatalyst in Ziegler-Natta catalyst systems and as a reducing agent in specific organic synthesis applications. Additionally, its long alkyl chains make it valuable in surface modification processes where hydrophobic properties are desired. Due to its pyrophoric classification, tridodecylalumane requires specialized storage and handling protocols, including protection from moisture and oxygen exposure. Transportation and storage must comply with regulations governing Class 4.2 dangerous goods. OYSI provides tridodecylalumane to European industrial customers requiring high-quality organoaluminum compounds for specialized chemical processes.

Frequently Asked Questions

What is tridodecylalumane?

Tridodecylalumane is an organoaluminum compound with the chemical formula C36H75Al and CAS number 1529-59-5. This substance consists of an aluminum atom bonded to three dodecyl groups (twelve-carbon alkyl chains), making it a trialkylaluminum derivative. With a molecular weight of 535 g/mol, it belongs to the family of organometallic compounds that are widely used in industrial applications requiring aluminum-carbon bonds.

What are the physicochemical properties of tridodecylalumane?

Tridodecylalumane is typically a viscous liquid or waxy solid at room temperature due to its long alkyl chains and high molecular weight of 535 g/mol. As an organoaluminum compound, it is highly sensitive to moisture and air, readily reacting with water and oxygen. The substance is generally insoluble in water but soluble in organic solvents such as hydrocarbons and ethers.

What is tridodecylalumane used for?

Tridodecylalumane is primarily used as a catalyst component in polymerization reactions, particularly in the production of polyolefins like polyethylene and polypropylene. It serves as a co-catalyst in Ziegler-Natta catalytic systems and can function as an alkylating agent in organic synthesis. The compound is also utilized in specialized industrial processes requiring controlled aluminum-carbon bond formation and as a precursor for other organoaluminum compounds.

How to handle tridodecylalumane safely?

Tridodecylalumane requires careful handling due to its pyrophoric nature and sensitivity to moisture. Always work in an inert atmosphere (nitrogen or argon) using appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Handle in well-ventilated areas or under fume hoods, keep away from ignition sources, and ensure dry conditions. Use proper transfer techniques with inert gas blanketing to prevent contact with air and moisture.

How to store tridodecylalumane correctly?

Tridodecylalumane must be stored under strict inert conditions in tightly sealed containers filled with dry nitrogen or argon gas. Keep in a cool, dry place away from heat sources, open flames, and oxidizing materials. Storage areas should be equipped with appropriate fire suppression systems and maintained at stable temperatures. The containers must be moisture-proof and compatible with organometallic compounds to prevent degradation and hazardous reactions.

What to do in case of contact with tridodecylalumane?

Tridodecylalumane contact requires immediate action due to its reactive nature. For skin contact, brush off any solid material carefully without using water, then flush with plenty of water and seek medical attention. In case of eye contact, rinse immediately with water for at least 15 minutes. If inhaled, move to fresh air and seek medical help. Never use water on fires involving this substance; use dry sand or appropriate dry chemical extinguishing agents instead.

How to dispose of tridodecylalumane appropriately?

Tridodecylalumane disposal requires specialized procedures due to its pyrophoric and reactive properties. The substance must be carefully quenched under controlled conditions using appropriate alcohols or other suitable quenching agents in an inert atmosphere. Disposal must comply with local and national hazardous waste regulations, typically requiring treatment by licensed hazardous waste contractors experienced in handling organometallic compounds. Never dispose of in regular waste streams or sewage systems.

How to transport tridodecylalumane?

Tridodecylalumane is classified under ADR Class 4.2 (spontaneously combustible substances) Packing Group I, indicating high danger level. Transportation requires specialized packaging that maintains inert atmosphere and prevents contact with moisture and air. Shipments must comply with dangerous goods regulations, including proper labeling, documentation, and handling procedures. Only qualified carriers experienced in transporting pyrophoric materials should handle such shipments, using appropriate safety protocols throughout the transport chain.

Is tridodecylalumane subject to specific regulations?

Tridodecylalumane is subject to various chemical safety regulations including REACH registration requirements in Europe for commercial use. As an organometallic compound, it falls under strict handling and storage regulations due to its pyrophoric nature. The substance is not classified as SVHC (Substance of Very High Concern) but must comply with CLP regulation for classification and labeling, workplace safety directives, and transport regulations for dangerous goods.

Where to buy tridodecylalumane in Europe?

Tridodecylalumane is available through OYSI, a specialized European distributor of technical chemicals with expertise in organometallic compounds. OYSI provides this substance to qualified industrial customers with proper handling capabilities and regulatory compliance. Due to the specialized nature and safety requirements of organometallic compounds, procurement typically involves technical consultation to ensure appropriate handling, storage, and application protocols are in place before delivery.
