Chloro-ethyl-(2-methylpropyl)alumane

Chloro-ethyl-(2-methylpropyl)alumane is an organoaluminum compound with the molecular formula C6H14AlCl and CAS number 13320-53-1. This chemical features an aluminum center bonded to an ethyl group, a 2-methylpropyl group, and a chlorine atom. With a molecular weight of 148.61 g/mol, it belongs to the class of organometallic compounds that are commonly used as catalysts and reagents in various chemical processes.

Chloro-ethyl-(2-methylpropyl)alumane is typically a liquid or low-melting solid at room temperature, characteristic of many organoaluminum compounds. As an organometallic substance, it is highly reactive with moisture and air, requiring anhydrous conditions for storage and handling. The compound is generally soluble in non-protic organic solvents such as hydrocarbons and ethers, but reacts violently with water and alcohols.

Chloro-ethyl-(2-methylpropyl)alumane is primarily used as a catalyst and 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 Ziegler-Natta catalysis systems. The compound is also utilized in specialized chemical manufacturing processes where controlled aluminum-carbon bond formation is required, making it valuable in pharmaceutical and fine chemical industries.

Chloro-ethyl-(2-methylpropyl)alumane requires strict safety protocols due to its pyrophoric nature and reactivity with moisture. Always wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Handle only under inert atmosphere conditions using nitrogen or argon gas. Work in well-ventilated areas or under fume hoods, and ensure all equipment is thoroughly dried before use to prevent violent reactions with trace moisture.

Chloro-ethyl-(2-methylpropyl)alumane must be stored under strictly anhydrous conditions in sealed containers under inert gas atmosphere. Store in a cool, dry place away from sources of ignition, moisture, and incompatible materials such as water, alcohols, and oxidizing agents. The storage area should be equipped with appropriate fire suppression systems and maintained at stable temperatures to prevent thermal decomposition or spontaneous ignition.

Immediate action is required if contact occurs with chloro-ethyl-(2-methylpropyl)alumane. For skin contact, do not use water as it may cause violent reactions; instead, carefully remove contaminated clothing and brush off any solid material before seeking medical attention. In case of eye contact, flush with mineral oil if available, then seek immediate medical care. For inhalation, move to fresh air immediately and get medical attention promptly.

Chloro-ethyl-(2-methylpropyl)alumane requires specialized disposal procedures due to its hazardous nature. Never dispose of this substance down drains or with regular waste. Contact licensed hazardous waste disposal companies that specialize in organometallic compounds. The material should be carefully neutralized under controlled conditions by trained professionals using appropriate quenching agents before final disposal, following all local and international waste regulations.

Chloro-ethyl-(2-methylpropyl)alumane is classified under ADR Class 4.2 (substances liable to spontaneous combustion) with Packing Group I, indicating high danger level. Transport requires specialized packaging approved for pyrophoric substances, with proper labeling and documentation. Shipments must be handled by carriers certified for dangerous goods transport, with appropriate emergency response procedures in place and protection from moisture throughout the transportation chain.

Chloro-ethyl-(2-methylpropyl)alumane is subject to various chemical regulations including REACH registration requirements in Europe for commercial use. While not classified as a Substance of Very High Concern (SVHC), it falls under dangerous goods regulations due to its pyrophoric properties. Users must comply with workplace safety regulations, proper classification and labeling requirements, and maintain safety data sheets for handling and emergency procedures.

Chloro-ethyl-(2-methylpropyl)alumane is available through OYSI, a specialized European distributor of technical chemicals and organometallic compounds. As a professional chemical supplier, OYSI provides this substance to qualified industrial customers with proper handling capabilities. Due to the specialized nature and safety requirements of this compound, procurement is typically limited to established chemical manufacturers, research institutions, and companies with appropriate safety infrastructure and expertise.
