Chloro(diethyl)alumane;dichloro(ethyl)alumane

Chloro(diethyl)alumane;dichloro(ethyl)alumane is an organoaluminum compound with the molecular formula C6H15Al2Cl3 and CAS number 12075-68-2. This chemical substance has a molecular weight of 247.5 g/mol and consists of aluminum atoms bonded to ethyl groups and chlorine atoms. It belongs to the family of alkylaluminum compounds, which are typically used as catalysts or intermediates in various chemical processes. The compound contains two aluminum centers with different substitution patterns of ethyl and chloro groups.

Chloro(diethyl)alumane;dichloro(ethyl)alumane is an organoaluminum compound that typically exists as a liquid or viscous substance at room temperature. Like most alkylaluminum compounds, it is highly reactive with moisture and air, leading to hydrolysis and oxidation reactions. The compound is generally colorless to pale yellow and has a characteristic organometallic odor. It is typically soluble in non-polar organic solvents such as hydrocarbons and ethers but reacts violently with water and alcohols.

Chloro(diethyl)alumane;dichloro(ethyl)alumane is primarily used as a catalyst or co-catalyst in various polymerization processes, particularly in the production of polyolefins such as polyethylene and polypropylene. It serves as an activator in Ziegler-Natta catalytic systems and other coordination polymerization reactions. The compound is also utilized in organic synthesis as a Lewis acid catalyst and as an intermediate in the preparation of other organoaluminum compounds. Additionally, it may be used in specialized chemical manufacturing processes requiring strong reducing agents.

Chloro(diethyl)alumane;dichloro(ethyl)alumane must be handled under strictly 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, and protective clothing. Work should be conducted in a well-ventilated area or under a fume hood. The compound requires careful handling due to its pyrophoric nature and reactivity with water. All equipment must be thoroughly dried before use, and proper fire suppression systems should be available.

Chloro(diethyl)alumane;dichloro(ethyl)alumane must be stored under strict inert atmosphere conditions in tightly sealed containers, preferably under nitrogen or argon gas. Storage areas should be cool, dry, and well-ventilated, away from sources of ignition and incompatible materials such as water, alcohols, and oxidizing agents. Containers should be made of suitable materials that do not react with organoaluminum compounds. The storage facility should be equipped with appropriate fire suppression systems and emergency response equipment for handling pyrophoric materials.

Immediate action is required in case of contact with chloro(diethyl)alumane;dichloro(ethyl)alumane due to its reactive nature. For skin contact, remove contaminated clothing immediately and flush the affected area with large amounts of water. In case of eye contact, rinse thoroughly with water for at least 15 minutes and seek immediate medical attention. If inhaled, move the person to fresh air immediately. Never use water directly on spilled material as it may cause violent reactions. Contact emergency services and provide them with the safety data sheet.

Chloro(diethyl)alumane;dichloro(ethyl)alumane must be disposed of as hazardous chemical waste according to local and national regulations. The compound should never be disposed of in regular waste streams or sewers due to its reactive nature. Disposal must be carried out by licensed hazardous waste management companies with expertise in handling pyrophoric and reactive chemicals. Small quantities may be carefully quenched with suitable alcohols under controlled conditions by trained professionals, but this should only be done following proper safety protocols and regulatory guidelines.

Chloro(diethyl)alumane;dichloro(ethyl)alumane is classified under ADR class 4.2 (substances liable to spontaneous combustion) with packing group I, indicating high danger level. Transportation requires specialized packaging designed for pyrophoric substances, typically under inert atmosphere. Vehicles must be equipped with appropriate fire suppression systems and emergency equipment. Drivers require special training for dangerous goods transport (ADR certification). Shipping documents must include proper shipping names, hazard classes, and emergency response information. Only authorized carriers experienced in handling pyrophoric chemicals should transport this substance.

Chloro(diethyl)alumane;dichloro(ethyl)alumane is subject to various chemical safety regulations including REACH registration requirements in Europe for substances manufactured or imported above certain tonnages. The compound must comply with CLP regulation for classification and labeling, though specific hazard classes may vary based on detailed assessment. As an organoaluminum compound, it may be subject to specific handling and storage regulations due to its pyrophoric properties. Users must ensure compliance with local workplace safety regulations and environmental protection laws governing reactive chemicals.
