Chloro(diethyl)alumane

Chloro(diethyl)alumane is an organoaluminum compound with the chemical formula C4H10AlCl and CAS number 96-10-6. This substance has a molecular weight of 120.56 g/mol and belongs to the class of alkylaluminum compounds. It is characterized by the presence of two ethyl groups and one chlorine atom bonded to an aluminum center, making it a valuable reagent in organometallic chemistry and industrial applications.

Chloro(diethyl)alumane is typically a colorless to pale yellow liquid at room temperature with a characteristic pungent odor. The compound is highly reactive and moisture-sensitive, readily decomposing in the presence of water or humid air. It has low solubility in polar solvents but dissolves well in anhydrous organic solvents such as hydrocarbons and ethers. The substance exhibits pyrophoric properties, meaning it can spontaneously ignite in air.

Chloro(diethyl)alumane serves as a crucial catalyst and reagent in various industrial processes, particularly in polymer production and organic synthesis. It is commonly used as a co-catalyst in Ziegler-Natta polymerization reactions for producing polyolefins. The compound also finds applications in alkylation reactions, as a reducing agent in organic synthesis, and in the preparation of other organoaluminum compounds for specialized chemical processes.

Chloro(diethyl)alumane requires handling under strict inert atmosphere conditions using nitrogen or argon gas to prevent contact with moisture and oxygen. Essential personal protective equipment includes chemical-resistant gloves, safety goggles, face shield, and flame-resistant clothing. All operations must be conducted in well-ventilated areas or fume hoods, away from ignition sources. Emergency shower and eyewash stations should be readily accessible, and trained personnel should always supervise handling procedures.

Chloro(diethyl)alumane must be stored in tightly sealed containers under an inert atmosphere in a cool, dry, and well-ventilated area. The storage area should be equipped with fire suppression systems and kept away from heat sources, sparks, and open flames. The substance is incompatible with water, alcohols, acids, and oxidizing agents. Storage containers should be made of materials compatible with organoaluminum compounds, and regular integrity checks are essential.

Immediate removal from exposure and medical attention are essential following contact with chloro(diethyl)alumane. For skin contact, gently brush off any solid material before flushing with copious amounts of water for at least 15 minutes. In case of eye contact, rinse immediately with water for 15-20 minutes while holding eyelids open. If inhaled, move the person to fresh air and provide respiratory support if needed. Never induce vomiting if ingested.

Chloro(diethyl)alumane disposal requires specialized hazardous waste management procedures in accordance with local and international regulations. The substance must be carefully quenched under controlled conditions using appropriate solvents before disposal. Disposal should only be performed by licensed hazardous waste contractors experienced in handling organoaluminum compounds. Empty containers must also be treated as hazardous waste and disposed of through authorized channels, never through regular waste streams.

Chloro(diethyl)alumane is classified as ADR Class 4.2 (substances liable to spontaneous combustion), Packing Group I, indicating high danger level. Transportation requires specialized packaging that prevents contact with air and moisture, using UN-approved containers with inert gas blanketing. Vehicles must carry appropriate emergency equipment and documentation. Only trained drivers with hazardous materials certification can transport this substance, following specific routing and emergency response protocols.

Chloro(diethyl)alumane is regulated under various European chemical legislation including REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals) and CLP (Classification, Labelling and Packaging) regulations. The substance is not currently listed as an SVHC (Substance of Very High Concern). However, its classification as ADR Class 4.2 subjects it to strict transport regulations, and handlers must comply with occupational safety standards and environmental protection requirements.
