Sourcing Aluminum Chloride Anhydrous? ChemicalDekho connects you with specialized inorganic manufacturers like GACL and Gulbrandsen. Secure high-activity catalysts for chemical synthesis and pigment production.
Aluminum Chloride Anhydrous (CAS 7446-70-0) is the classic Lewis Acid catalyst. It drives Friedel-Crafts alkylation and acylation reactions, essential for making Ethylbenzene (Styrene), Detergent Alkylates (LAB), and Pharma intermediates like Ibuprofen. It is also used in the production of dyestuffs (Anthraquinone) and Titanium Dioxide.
**HANDLING WARNING:** This material is extremely hygroscopic and fumes in moist air, releasing HCl gas. Supply is packed in nitrogen-sealed steel drums or specialized PVC bags.

Causes severe skin burns and eye damage. Reacts violently with water or moisture to release toxic Hydrogen Chloride (HCl) gas. Corrosive to metals.
When exposed to air, it reacts with humidity (water vapor) to form Aluminum Hydroxide and HCl gas. The 'smoke' is actually acid mist.
It is a famous organic reaction used to attach carbon chains to benzene rings. Aluminum Chloride is the essential catalyst that makes this happen.
No. PAC is partially hydrolyzed (reacted with water). Anhydrous AlCl3 has NO water and is much more reactive and dangerous.
NEVER use water. Cover with dry sand or earth. If you add water to a large spill, it can cause an explosion of acid steam.
