Product Overview
Diethylaluminium chloride (DEAC) is a highly reactive organoaluminium compound supplied as a 0.9M solution in toluene, ensuring stability and ease of handling. This AcroSeal® grade product is meticulously packaged under inert conditions to prevent moisture contamination, making it ideal for air-sensitive applications. The solution exhibits strong Lewis acidity, making it a versatile catalyst in organic synthesis, particularly in polymerization and Friedel-Crafts reactions. Its controlled molar concentration (0.9M) allows for precise stoichiometric calculations in laboratory procedures. The toluene solvent provides excellent solubility for the aluminium compound while maintaining low viscosity for easy dispensing. Due to its pyrophoric nature, this solution must be stored and handled under an inert atmosphere, such as nitrogen or argon. The AcroSeal® packaging features a septum cap for syringe extraction, minimizing exposure to air and moisture during use. This product is particularly valued in research settings where reproducibility and purity are critical, as the sealed packaging prevents degradation during storage and transport.
FAQs
1. What is the shelf life of Diethylaluminium chloride 0.9M solution when stored properly?
The solution remains stable for 12-18 months from the date of manufacture when stored under inert gas at temperatures between 2-8°C in its original unopened AcroSeal® packaging. Always check the bottle label for the exact expiration date as stability may vary based on storage conditions and frequency of opening.
2. Can this solution be used directly in polymerization reactions without further purification?
The AcroSeal® grade is supplied at high purity and is generally suitable for direct use in most polymerization applications. However, for highly sensitive reactions, some researchers prefer additional purification steps like filtration through a dry, inert support material to remove any potential particulate contaminants that might have formed during storage.
3. What safety precautions are essential when handling this toluene solution?
This product is extremely moisture-sensitive and pyrophoric. Always handle in a well-ventilated fume hood using dry, inert gas purged equipment. Wear appropriate PPE including flame-resistant lab coat, chemically resistant gloves, and safety goggles. Never use glass syringes as they may bind with the aluminium compound; PTFE or stainless steel syringes are recommended for transfer operations.
4. How does the 0.9M concentration compare to other available concentrations for similar applications?
The 0.9M concentration offers a balance between reactivity and ease of handling. Lower concentrations (typically 0.5M-1.0M) are preferred for reactions requiring precise control over aluminium content, while higher concentrations (1.5M-2.0M) are used when minimizing solvent volume is critical. This concentration is particularly suitable for most standard organic synthesis applications where moderate reactivity is desired.
5. What is the recommended procedure for disposing of unused Diethylaluminium chloride solution?
Unused solution should be carefully neutralized by slow addition to a large volume of isopropanol or another suitable alcohol in a well-ventilated fume hood, followed by dilution with water. The neutralized solution can then be disposed of according to local regulations for aluminium-containing chemical waste. Never dispose of active solution directly down the drain or in regular trash containers.
