Aluminum chloride #CAS7446-70-0
Aluminum chloride, or aluminum trichloride, with the chemical formula AlCl3, is a compound of chlorine and aluminum. Aluminum chloride has a very low melting and boiling point and sublimates, making it an ionic covalent compound. Molten aluminum chloride is poorly conductive, unlike most halide salts (such as sodium chloride).
Industrial grade aluminum chloride contains impurities such as iron and free chlorine, and is pale yellow, yellowish-green, or reddish-brown. Its molecular weight is 133.34. Its density is 2.44 (25°C). It has a strong hydrochloric acid odor. It is readily soluble in water, releasing heat. It is soluble in organic solvents such as ethanol, ether, and carbon tetrachloride. It is highly hygroscopic and readily deliquesces, producing hydrogen chloride fumes. It is highly corrosive. It is used as a catalyst in organic synthesis. It is produced by reacting metallic aluminum with chlorine, or by roasting alumina with petroleum coke followed by chlorination.
Application of Aluminum chloride
Aluminum chloride has extensive commercial applications. It is used primarily in the electrolytic production of aluminum. Another major use involves its catalytic applications in many organic reactions, including Friedel-Crafts alkylation, polymerization, isomerization, hydrocracking, oxidation, decarboxylation, and dehydrogenation. It is also used in the production of rare earth chlorides, electroplating of aluminum and in many metal finishing and metallurgical operations.
A yellowish-white crystalline or granular powder made by passing chlorine gas over alumina in a heated state and collecting the product by sublimation. Aluminum chloride was occasionally used in gold and platinum toning baths.
Aluminum chloride is used as a catalyst in many organic reactions.
