Characteristic
Aluminium chloride (AlCl3), also known as aluminium trichloride, is the main compound of aluminium and chlorine. It is white, but samples are often contaminated with iron(III) chloride, giving it a yellow color.
Chemical formula：AlCl3
Molar mass：133.341 g/mol (anhydrous)
241.432 g/mol (hexahydrate)
Appearance：white or pale yellow solid, hygroscopic
Density：2.48 g/cm3 (anhydrous);2.398 g/cm3 (hexahydrate)
Melting point：192.6 °C (378.7 °F; 465.8 K)
(anhydrous);100 °C (212 °F; 373 K)(hexahydrate, dec.)
Boiling point：180 °C (356 °F; 453 K) (sublimes)
Solubility：soluble in hydrogen chloride, ethanol, chloroform, carbon tetrachloride;slightly soluble in benzene
Vapor pressure:133.3 Pa (99 °C);13.3 kPa (151 °C)
Viscosity:0.35 cP (197 °C);0.26 cP (237 °C)
Crystal structure:Monoclinic, mS16
Application
Aluminum chloride is used to control excessive sweating. It is commonly used as a catalyst for the halogenation (especially chlorination) of aromatic groups, as well as in the Friedel Crafts reaction. It is also used in the Meerwein-Ponndorf-Verley reduction. It is widely used in the manufacturing of petrochemicals such as alkylbenzene, ethylbenzene, alkyl aryl ketone, ethyl chloride. It is used for making detergents, polymerization and isomerization reactions of hydrocarbons.
