General description

Aluminum chloride (AlCl3) is a pure compound formed by the exothermic reaction of metallic aluminum and hydrogen chloride (HCl) in the temperature range of 650-750 °C. It is majorly utilized as a catalyst in Friedel-Crafts reactions.

Application

AlCl3 can be used as a catalyst in a variety of reactions such as polymerization, isomerization, Gettermann-Koch reaction and Lewis-acid catalyzed reaction for the preparation of ethylbenzene, anthraquinone and a variety of compounds, which can be used in the development of detergents.

Features and Benefits

The vapor-phase co-reductions with other metal halides by hydrogen results in finely divided intermetallics with applications as structural materials or compounds with useful thermoelectric, magnetic, and oxidation-resistance properties. Aluminum nitride can be synthesized from the elemnts with AlCl3 added to help facilitate crystallization.
