Product Name – Ethylaluminium dichloride, 1.8M solution in toluene, AcroSeal® Quantity/Pack Size – 100ML, 800ML Form – Liquid (solution in toluene) Grade – Laboratory grade (1.8M concentration) Application – Catalyst in organic synthesis, polymerization, Lewis acid reactions
Product Overview
Ethylaluminium dichloride (1.8M in toluene) is a highly reactive organoaluminium compound supplied in an airtight AcroSeal® packaging to prevent moisture contamination and oxidation. This solution is stabilized in anhydrous toluene, ensuring consistent performance in sensitive chemical processes. The 1.8 molar concentration provides an optimal balance between reactivity and handling safety, making it suitable for applications requiring precise stoichiometric control. As a strong Lewis acid, it functions as an efficient catalyst in Friedel-Crafts reactions, olefin polymerization, and other transformations where aluminum-based reagents are critical. The AcroSeal® technology guarantees long-term stability by minimizing exposure to atmospheric moisture, while the toluene solvent enhances solubility and ease of dispensing. This product is rigorously tested for purity, with residual chloride and metal impurities maintained below thresholds that could interfere with high-sensitivity reactions. Compatible with standard Schlenk techniques, it integrates seamlessly into inert-atmosphere workflows, reducing the risk of side reactions or decomposition during storage or use.
FAQs
1. What precautions are needed when handling Ethylaluminium dichloride in toluene?
This compound is pyrophoric and reacts violently with water or air. Always handle under an inert atmosphere (argon/nitrogen) using air-free techniques. Wear flame-resistant gloves, safety goggles, and work in a fume hood. Avoid glassware with ground joints to prevent seizing due to aluminum salt formation.
2. Can this solution be diluted further for lower concentration reactions?
Yes, but dilution must be performed under strict anhydrous conditions using dry, oxygen-free solvents like hexane or toluene. Use a syringe or cannula transfer under inert gas to maintain purity. Recheck concentration via titration if precise stoichiometry is required.
3. How does AcroSeal® packaging improve stability compared to standard bottles?
AcroSeal® uses a patented septum-and-cap system that creates a hermetic seal, eliminating headspace oxygen and moisture ingress. Unlike traditional screw caps, it prevents solvent evaporation and contamination during repeated access, extending shelf life by up to 24 months when stored properly.
4. What are the signs of decomposition in this product?
Decomposition may present as visible precipitation (aluminum oxides/hydroxides), discoloration (darkening of the solution), or gas evolution. A sharp increase in viscosity or the presence of solid particles indicates moisture contamination. Discard if any of these signs appear, as decomposed product can catalyze unintended side reactions.
5. Is this compatible with stainless steel or PTFE lab equipment?
Stainless steel is generally compatible for short-term contact, but prolonged exposure may lead to corrosion due to the chloride content. PTFE (Teflon) is the preferred material for syringes, tubing, and reaction vessels, as it resists both the organoaluminium compound and toluene solvent without leaching contaminants.
