Anhydrous aluminum chloride (CAS 7446-70-0, AlCl3) is a powerful Lewis acid. It is the classic catalyst for Friedel-Crafts acylation and alkylation and serves as a chemical intermediate for numerous aluminum compounds, with further use in petroleum cracking and the manufacture of rubbers and lubricants.
Frequently Asked Questions
What is anhydrous aluminum chloride used for?
Anhydrous aluminum chloride (CAS 7446-70-0, AlCl3) is a powerful Lewis acid and the classic catalyst for Friedel-Crafts acylation and alkylation. It also serves as a chemical intermediate for numerous aluminum compounds and is used in petroleum cracking and in the manufacture of rubbers and lubricants.
What is the chemical formula and CAS number for anhydrous aluminum chloride?
Anhydrous aluminum chloride has the formula AlCl3 and CAS 7446-70-0. This is the technical-grade anhydrous powder; it differs from aluminum chloride hexahydrate. Purity is confirmed on the Certificate of Analysis per lot.
What is the difference between anhydrous aluminum chloride and the hexahydrate?
The anhydrous form (AlCl3, CAS 7446-70-0) is the active Lewis-acid catalyst used in Friedel-Crafts chemistry; the hexahydrate (AlCl3·6H2O) is a different material and is not interchangeable as a catalyst. This product is the anhydrous technical-grade powder. Specify the form you need when ordering.
How is anhydrous aluminum chloride shipped (DOT/UN)?
Anhydrous aluminum chloride ships under UN 1726. Because it is moisture-reactive, packaging and the shipping description must follow the SDS — confirm details with your carrier. We supply the powder in sealed drums and bulk packaging.
What is the cost of bulk anhydrous aluminum chloride?
Bulk pricing depends on purity grade and order volume. We supply manufacturers in moisture-protected drums and bulk packaging — request a quote with your target grade and tonnage for current pricing, SDS, and CoA.
