Alumiinkloridi

Alumiinkloridi is the chemical compound with the formula AlCl3. It exists as a covalent compound in the solid state and is a white crystalline solid that readily sublimes in dry air. When exposed to moist air, it hydrolyzes to form aluminum hydroxide and hydrogen chloride gas, giving off a pungent odor. Alumiinkloridi is highly soluble in water, and its solutions are acidic due to hydrolysis.

Industrially, Alumiinkloridi is produced by the exothermic reaction of aluminum with chlorine gas at high temperatures. It is also manufactured by reacting aluminum oxide with chlorine in the presence of carbon. A significant application of Alumiinkloridi is as a catalyst in organic chemistry, particularly in Friedel-Crafts reactions, which are used to alkylate or acylate aromatic rings. It is also employed in the production of other aluminum compounds, in the refining of aluminum metal, and in the manufacture of dyes and perfumes. In antiperspirants, anhydrous aluminum chloride is used as an active ingredient to block sweat ducts.
