Chloro-bis(2-methylpropyl)alumane

Chloro-bis(2-methylpropyl)alumane is an organoaluminum compound with the molecular formula C8H18AlCl and CAS number 1779-25-5. This chemical features an aluminum center bonded to a chlorine atom and two 2-methylpropyl (isobutyl) groups. With a molecular weight of 176.66 g/mol, it belongs to the family of alkylaluminum compounds commonly used in industrial applications requiring aluminum-carbon bonds for chemical synthesis and catalysis.

Chloro-bis(2-methylpropyl)alumane is typically a liquid or low-melting solid at room temperature, characteristic of organoaluminum compounds. Like most alkylaluminum derivatives, it is highly reactive with moisture and oxygen, requiring inert atmosphere handling. The compound is generally soluble in hydrocarbon solvents and ethers but reacts violently with water and alcohols. Its high reactivity stems from the polar aluminum-carbon bonds and the electrophilic nature of the aluminum center.

Chloro-bis(2-methylpropyl)alumane serves primarily as a catalyst or co-catalyst in polymerization reactions, particularly in the production of polyolefins and other synthetic polymers. It functions as an alkylating agent in organic synthesis and as a precursor for preparing other organoaluminum compounds. The chemical is also utilized in Ziegler-Natta catalysis systems and various industrial processes requiring controlled aluminum alkylation or as a reducing agent in specialized chemical transformations.

Chloro-bis(2-methylpropyl)alumane requires handling under strict inert atmosphere conditions using nitrogen or argon gas. Essential protective equipment includes chemical-resistant gloves, safety goggles, and protective clothing. Work must be conducted in well-ventilated areas or fume hoods due to potential vapor hazards. Avoid contact with moisture, water, and oxidizing materials as these cause vigorous reactions. Use only dry, clean equipment and maintain strict exclusion of air and moisture throughout all handling procedures.

Chloro-bis(2-methylpropyl)alumane must be stored under inert atmosphere in tightly sealed containers, preferably under nitrogen or argon gas. Storage areas should be cool, dry, and well-ventilated, away from heat sources and incompatible materials. Keep strictly separated from water, alcohols, acids, and oxidizing agents. Use only clean, dry storage vessels made of compatible materials. Regular monitoring of container integrity and inert atmosphere maintenance is essential to prevent degradation and hazardous reactions.

Immediate action is required for any contact with chloro-bis(2-methylpropyl)alumane. For skin contact, remove contaminated clothing and flush affected areas with copious amounts of water for at least 15 minutes. In case of eye contact, rinse immediately with water and seek medical attention. If inhaled, move to fresh air immediately. Never use water directly on spills due to violent reaction risk. Seek immediate medical attention for all exposure incidents and provide safety data sheet information to medical personnel.

Chloro-bis(2-methylpropyl)alumane disposal requires specialized hazardous waste management procedures due to its reactive nature. The material must be carefully quenched using appropriate methods under controlled conditions by trained personnel. Disposal must comply with local and European waste regulations for hazardous chemicals. Never dispose of in regular waste streams or pour down drains. Contact licensed hazardous waste disposal companies experienced in handling reactive organometallic compounds for proper treatment and disposal.

Chloro-bis(2-methylpropyl)alumane is classified under ADR Class 4.2 (Substances liable to spontaneous combustion), Packing Group I, indicating high transport risk. Transportation requires specialized packaging meeting UN specifications for this hazard class. Vehicles must carry appropriate emergency equipment and documentation. Only trained personnel should handle transport operations. Shipments must comply with all ADR regulations including proper labeling, documentation, and emergency response procedures. Professional logistics companies experienced with reactive chemicals should manage transportation.

Chloro-bis(2-methylpropyl)alumane falls under European REACH regulation requiring registration for commercial use. While not currently listed as an SVHC (Substance of Very High Concern), it must comply with CLP classification and labeling requirements. The substance is subject to ADR transport regulations as Class 4.2 material. Industrial users must maintain safety data sheets and follow occupational exposure guidelines. Specific national regulations may apply depending on use and quantities handled within different European jurisdictions.
