Dichloro(2-methylpropyl)alumane

Dichloro(2-methylpropyl)alumane is an organoaluminum compound with the molecular formula C4H9AlCl2 and CAS number 1888-87-5. This chemical features an aluminum atom bonded to two chlorine atoms and a 2-methylpropyl group (isobutyl group). With a molecular weight of 155 g/mol, it belongs to the family of alkylaluminum chlorides used primarily as catalysts and intermediates in organic synthesis.

Dichloro(2-methylpropyl)alumane is typically a colorless to pale yellow liquid at room temperature with a characteristic sharp, pungent odor. As an organoaluminum compound, it is highly reactive with moisture and air, readily hydrolyzing in the presence of water to form aluminum hydroxide and hydrochloric acid. It is soluble in non-polar organic solvents but reacts violently with protic solvents.

Dichloro(2-methylpropyl)alumane is primarily used as a 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 an intermediate in the preparation of other organoaluminum compounds. The compound is also utilized in specialty chemical manufacturing processes requiring selective aluminum-based catalysis.

Dichloro(2-methylpropyl)alumane must be handled under strict 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 due to its reactive nature. Avoid contact with moisture, air, and incompatible materials. Emergency eyewash and safety shower facilities should be readily accessible.

Dichloro(2-methylpropyl)alumane must be stored in tightly sealed containers under inert gas atmosphere (nitrogen or argon) to prevent hydrolysis and oxidation. Storage areas should be cool, dry, and well-ventilated, away from sources of moisture, heat, and ignition. The compound should be kept separate from water, alcohols, acids, and oxidizing agents to prevent dangerous reactions.

In case of skin contact with dichloro(2-methylpropyl)alumane, immediately remove contaminated clothing and flush the affected area with copious amounts of water for at least 15 minutes. For eye contact, rinse immediately with water and seek medical attention. If inhaled, move the person to fresh air and seek medical help. Never use water directly on spills due to violent reaction potential.

Dichloro(2-methylpropyl)alumane must be disposed of according to local and national hazardous waste regulations as a reactive chemical waste. The compound should be carefully neutralized by trained professionals using appropriate inert solvents before disposal. Contact licensed hazardous waste disposal companies for proper treatment. Never dispose of this material down drains or with regular waste due to its reactive properties.

Dichloro(2-methylpropyl)alumane is classified under ADR Class 4.2 (substances liable to spontaneous combustion) with Packing Group I, indicating high danger. Transportation requires special packaging that prevents contact with air and moisture, proper labeling with Class 4.2 hazard labels, and compliance with dangerous goods transport regulations. Only qualified carriers experienced with pyrophoric materials should handle transportation.

Dichloro(2-methylpropyl)alumane is subject to various chemical regulations including REACH registration requirements in Europe for commercial use. While not classified as an SVHC (Substance of Very High Concern), it falls under general chemical safety regulations due to its reactive nature. Users must comply with workplace safety standards, transportation regulations (ADR Class 4.2), and local environmental protection requirements.
