Description:- Aluminum chloride (AlCl3), also known as aluminum trichloride, describe compounds with the formula AlCl3(H2O)n (n = 0 or 6). They consist of aluminum and chlorine atoms in a 1:3 ratio, and one form also contains six waters of hydration. Both are white solids, but samples are often contaminated with iron(III) chloride, giving a yellow color. The anhydrous material is important commercially. It has a low melting and boiling point. It is mainly produced and consumed in the production of aluminum metal, but large amounts are also used in other areas of the chemical industry.The compound is often cited as a Lewis acid. It is an example of an inorganic compound that reversibly changes from a polymer to a monomer at mild temperature.
Anhydrous Aluminum Chloride is used as a catalyst in the processing of pharmaceuticals, agricultural chemicals, polymers, flavors and fragrances.
