Aluminium chloride

CAS number : 7446-70-0

Molecular weight :133.34

Molecular formula/chemical symbol :AlCl3

Description :
 

Aluminium chloride (AlCl3) is the main compound of aluminium and chlorine. It is white, but samples are often contaminated with iron trichloride, giving it a yellow colour. The solid has a low melting and boiling point. It is mainly produced and consumed in the production of aluminium metal, but large amounts are also used in other areas of chemical industry. The compound is often cited as a Lewis acid. It is an example of an inorganic compound that "cracks" at mild temperature, reversibly changing from a polymer to a monomer.

USES :

Aluminium Chloride is Used as a catalyst in the process of Friedel Crafts. (It has an electron deficient molecule forming only 3 bonds, and has no lone pairs. The catalyst acts as an electron acceptor for a lone pair on the halide atom). It is widely used in the manufacturing of petrochemicals such as alkylbenzene, ethylbenzene, alkyl aryl ketone, ethyl chloride. It is also used in the manufacturing pharmaceuticals, dyes intermediates and other organics chemicals such as anthraquinone, phthalocyanines, acetophenone, butyl rubber, phenylethyl alcohols. It is used as a nucleu inhibitor in the production of titanium dioxide. Aluminum Chloride is also used in the production of aluminum, in the metallurgical industry and as a flux in aluminum smelting; in the production of rubber; lubricants and wood preservatives, and in cosmetics as an astringent; active ingredient in antiperspirants.
