Chloro(dimethyl)alumane;dichloro(methyl)alumane

Chloro(dimethyl)alumane;dichloro(methyl)alumane is an organoaluminum compound with the molecular formula C3H9Al2Cl3 and CAS number 12542-85-7. This chemical consists of two aluminum centers bonded to methyl groups and chlorine atoms, forming a dimeric structure. With a molecular weight of 205.42 g/mol, it belongs to the family of alkylaluminum chlorides used primarily in industrial applications requiring aluminum-carbon bonds.

Chloro(dimethyl)alumane;dichloro(methyl)alumane is typically a colorless to pale yellow liquid or solid at room temperature, depending on concentration and purity. As an organoaluminum compound, it is highly reactive with moisture and oxygen, producing aluminum hydroxide and hydrocarbons. It is soluble in non-polar organic solvents but reacts violently with water and protic solvents, making it air and moisture sensitive.

Chloro(dimethyl)alumane;dichloro(methyl)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 as a precursor for other organoaluminum compounds. Industrial applications include Ziegler-Natta catalysis systems, chemical vapor deposition processes, and as a reducing agent in specialized chemical manufacturing operations.

Chloro(dimethyl)alumane;dichloro(methyl)alumane must be handled under 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 to prevent inhalation exposure. Due to its pyrophoric nature, avoid contact with air, moisture, and incompatible materials. Use non-sparking tools and maintain strict exclusion of water and oxygen during handling procedures.

Chloro(dimethyl)alumane;dichloro(methyl)alumane should be stored under inert gas atmosphere in tightly sealed containers, preferably under nitrogen or argon. Storage areas must be dry, cool, and well-ventilated, away from sources of ignition, heat, and moisture. Keep containers away from incompatible materials such as water, alcohols, acids, and oxidizing agents. Storage facilities should comply with regulations for pyrophoric substances and include appropriate fire suppression systems.

In case of skin contact with chloro(dimethyl)alumane;dichloro(methyl)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 provide respiratory support if needed. Do not induce vomiting if ingested. Seek immediate medical attention in all cases of exposure and provide safety data sheet to medical personnel.

Chloro(dimethyl)alumane;dichloro(methyl)alumane must be disposed of according to local and national hazardous waste regulations. The compound should be carefully neutralized by qualified personnel using appropriate techniques under controlled conditions. Disposal must be conducted by licensed hazardous waste contractors who specialize in organoaluminum compounds. Never dispose of this material in regular waste streams, sewers, or water systems due to its reactive and potentially harmful nature.

Chloro(dimethyl)alumane;dichloro(methyl)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, typically under inert gas. Vehicles must carry appropriate hazard placards and emergency response information. Only trained personnel should handle transportation, and carriers must comply with dangerous goods regulations including proper documentation, labeling, and emergency procedures.

Chloro(dimethyl)alumane;dichloro(methyl)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 must comply with CLP regulation for classification, labeling, and packaging. Industrial users must follow workplace safety regulations and may require specific permits for handling pyrophoric substances. Export/import may be subject to additional trade regulations depending on jurisdiction.
