Ethoxy(diethyl)alumane

Ethoxy(diethyl)alumane is an organoaluminum compound with the molecular formula C6H15AlO and CAS number 1586-92-1. This chemical features an aluminum center bonded to two ethyl groups and one ethoxy group, making it a trisubstituted aluminum derivative. With a molecular weight of 130.16 g/mol, it belongs to the family of alkylaluminum compounds commonly used in organometallic chemistry and industrial applications requiring aluminum-carbon bonds.

Ethoxy(diethyl)alumane is typically a liquid organoaluminum compound that is highly reactive with moisture and air. Like most alkylaluminum compounds, it is likely colorless to pale yellow and has a characteristic organometallic odor. The compound is moisture-sensitive and will react vigorously with water, alcohols, and other protic solvents. It is soluble in non-polar organic solvents such as hydrocarbons and ethers but must be handled under inert atmosphere conditions.

Ethoxy(diethyl)alumane 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 as a reducing agent in various chemical processes. The compound is also utilized in the preparation of other organometallic compounds and as a precursor for aluminum-containing materials in specialized industrial applications requiring controlled aluminum delivery.

Ethoxy(diethyl)alumane must be handled under strict inert atmosphere conditions using nitrogen or argon gas. Personnel should wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. All work should be conducted in well-ventilated areas or under fume hoods. Avoid contact with moisture, water, alcohols, and oxidizing agents. Use dry, inert solvents only and ensure all equipment is thoroughly dried before use to prevent violent reactions.

Ethoxy(diethyl)alumane should be stored in tightly sealed containers under inert atmosphere (nitrogen or argon) at controlled temperature conditions. Storage areas must be dry, well-ventilated, and protected from heat sources and direct sunlight. Keep away from water, alcohols, acids, bases, and oxidizing materials to prevent dangerous reactions. Containers should be made of compatible materials and regularly inspected for integrity. Storage facilities should have appropriate fire suppression systems designed for flammable liquids.

Ethoxy(diethyl)alumane contact requires immediate emergency response due to its reactive nature. For skin contact, do not use water directly - first remove with a dry cloth, then flush with copious amounts of water and seek medical attention. For eye contact, rinse immediately with water for at least 15 minutes and get emergency medical care. If inhaled, move to fresh air and seek medical attention. In case of fire, use dry chemical extinguishers - never use water-based extinguishers.

Ethoxy(diethyl)alumane disposal must follow hazardous waste regulations and requires careful neutralization by trained professionals. The compound should be carefully quenched with appropriate alcohols under controlled conditions, never with water directly. Disposal must be conducted through licensed hazardous waste contractors familiar with organometallic compounds. Empty containers may still contain reactive residues and require special treatment. Consult local environmental authorities and waste management specialists for proper disposal procedures and documentation requirements.

Ethoxy(diethyl)alumane is classified under ADR Class 4.2 (substances liable to spontaneous combustion), Packing Group I, indicating high danger level. Transportation requires specialized packaging that prevents contact with moisture and air, using UN-approved containers with proper labeling and documentation. Vehicles must comply with ADR regulations for Class 4.2 materials, including appropriate placarding, emergency equipment, and trained drivers. Shipping documentation must include proper shipping names, hazard classes, and emergency contact information.

Ethoxy(diethyl)alumane is subject to various chemical safety regulations including REACH registration requirements in Europe for commercial use. While not classified as a Substance of Very High Concern (SVHC), it must comply with CLP regulation for classification, labeling, and packaging. Industrial users must implement appropriate risk management measures and maintain safety data sheets. Transportation is regulated under ADR/RID dangerous goods regulations, and workplace exposure may be subject to occupational health and safety requirements.
