Aluminum chloride hexahydrate is a white to pale yellow crystalline inorganic compound commonly used as a catalyst and in water treatment.
🏭⚗️ Production
It is produced by dissolving aluminum metal or aluminum hydroxide in hydrochloric acid, followed by crystallization to form the hexahydrate form (AlCl₃·6H₂O).
🔬 Properties
The chemical formula is AlCl₃·6H₂O with a molar mass of approximately 241.43 g/mol. It appears as pale yellow crystals, is highly soluble in water, and forms acidic solutions. It is hygroscopic and decomposes upon heating, releasing hydrogen chloride gas.
🧪 Applications
Aluminum chloride hexahydrate is widely used as a Lewis acid catalyst in organic synthesis, in water purification as a flocculant, and in deodorants and antiperspirants. It is also used in dyeing and textile industries.
⚠️ Safety
It is corrosive and can cause severe skin and eye irritation. Inhalation of dust or fumes may cause respiratory tract irritation. Proper protective equipment such as gloves, goggles, and masks should be used when handling. Store in a cool, dry place away from moisture and incompatible substances.
