Aluminum Chloride (AlCl₃) FAQ
What are the primary industrial uses of Aluminum Chloride (AlCl₃)?
Aluminum Chloride (AlCl₃) is primarily used as a Lewis acid catalyst in organic chemistry reactions, particularly in Friedel-Crafts alkylation and acylation. It's also extensively employed in water treatment as a flocculating agent to remove impurities, in the production of petrochemicals, and as an active ingredient in antiperspirants at lower concentrations.
How should Aluminum Chloride (AlCl₃) be stored safely?
Store Aluminum Chloride (AlCl₃) in airtight containers made of materials resistant to corrosion (HDPE, glass, or stainless steel). Keep containers in a cool, dry, well-ventilated area away from moisture and incompatible substances like water, bases, and oxidizers. The storage area should have proper secondary containment and appropriate labels indicating the material's hazards.
What safety precautions are necessary when handling Aluminum Chloride (AlCl₃)?
Always wear appropriate PPE including chemical-resistant gloves, safety goggles, and a respirator when handling powdered Aluminum Chloride (AlCl₃). Work in a fume hood when possible, as the compound reacts vigorously with water to release hydrogen chloride gas. Have emergency eyewash and shower stations accessible, and never handle without proper training in chemical safety procedures.
