Chloro-ethyl-(2-methylpropyl)alumane

Chloro-ethyl-(2-methylpropyl)alumane is an organoaluminum compound with the molecular formula C6H14AlCl and CAS number 13320-53-1. This chemical features an aluminum center bonded to an ethyl group, a 2-methylpropyl group, and a chlorine atom. With a molecular weight of 148.61 g/mol, it belongs to the family of alkylaluminum compounds commonly used in industrial applications requiring aluminum-carbon bonds.

Chloro-ethyl-(2-methylpropyl)alumane is typically a liquid or low-melting solid at room temperature due to its organoaluminum structure. Like most alkylaluminum compounds, it is highly reactive with moisture and oxygen, requiring anhydrous conditions for stability. The compound is likely colorless to pale yellow and exhibits high reactivity toward protic solvents. Its molecular structure makes it soluble in non-polar organic solvents but incompatible with water.

Chloro-ethyl-(2-methylpropyl)alumane is primarily used as a catalyst or co-catalyst in polymerization reactions, particularly in the production of polyolefins. It serves as an alkylating agent in organic synthesis and can be employed in Ziegler-Natta catalysis systems. The compound is also utilized in aluminum-carbon bond forming reactions and as a reducing agent in specialized chemical processes requiring controlled aluminum delivery.

Chloro-ethyl-(2-methylpropyl)alumane must be handled under strict anhydrous 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 inert atmosphere to prevent moisture contact. Use non-sparking tools and avoid contact with water or alcohols. Emergency shower and eyewash stations should be readily accessible during handling operations.

Chloro-ethyl-(2-methylpropyl)alumane must be stored in tightly sealed containers under inert gas atmosphere, typically nitrogen or argon, to prevent moisture and oxygen exposure. Storage areas should be cool, dry, and well-ventilated, away from water sources, alcohols, and oxidizing agents. Containers should be made of compatible materials and regularly inspected for integrity. Emergency response equipment must be available in storage areas.

In case of skin contact with chloro-ethyl-(2-methylpropyl)alumane, immediately remove contaminated clothing and flush the affected area with large amounts of water for at least 15 minutes. For eye contact, rinse thoroughly with water and seek immediate medical attention. If inhaled, move the person to fresh air and provide respiratory support if needed. Never use water on spilled material due to violent reaction potential. Seek immediate medical attention for all exposures.

Chloro-ethyl-(2-methylpropyl)alumane disposal must be performed by licensed hazardous waste contractors following local and European waste regulations. The compound cannot be disposed of through normal drainage systems due to its reactivity with water. Controlled hydrolysis or incineration under specialized conditions may be required. Consult local environmental authorities for specific disposal requirements and ensure proper waste classification documentation is maintained throughout the disposal process.

Chloro-ethyl-(2-methylpropyl)alumane is classified under ADR Class 4.2 (Substances liable to spontaneous combustion), Packing Group I, indicating high transport risk. Special packaging requirements include hermetically sealed containers with inert gas protection and appropriate hazard labeling. Transportation must comply with dangerous goods regulations, requiring trained personnel and proper documentation. Vehicles must be equipped with appropriate emergency response equipment and follow designated routing restrictions.

Chloro-ethyl-(2-methylpropyl)alumane is subject to standard European chemical regulations including REACH registration requirements and CLP classification rules. The compound is not listed as a Substance of Very High Concern (SVHC) but must comply with standard industrial chemical handling and reporting requirements. Users must maintain safety data sheets and ensure proper risk assessments are conducted before use in accordance with European occupational safety regulations.

Chloro-ethyl-(2-methylpropyl)alumane is available through OYSI, a specialized European distributor of technical chemicals serving industrial customers across Europe. OYSI provides this organoaluminum compound with proper documentation, safety data sheets, and regulatory compliance support. As a specialty chemical requiring expert handling, procurement should only be made through qualified distributors who understand the technical requirements and safety protocols necessary for this reactive compound.
