AlCl3.6H2O

UsesThe Aluminium chloride hexahydrate is used in the preparation of deodorant and antiperspirant. Also, it is applied in textile finishing to improve the antistatic characteristics and flammability ratings of various textile materials. Commercially, it is sold as crystalline powder or as a 28% solution in water.

UsesThe anhydrous form suitable as an acid catalyst, especially in Friedel-Crafts type reactions; in cracking of petroleum; in manufacture of rubbers, lubricants. The hexahydrate form used in preserving wood; disinfecting stables, slaughterhouses, etc.; in deodorants and antiperspirant preparations; refining crude oil; dyeing fabrics; manufacture of parchment paper.

Usesin preserving wood, disinfecting stables, etc.; in deodorants and antiperspirant preparations; in refining crude oil, and dyeing fabrics; in dental ceramics; in topical astringents

UsesPharmaceutical preparations of aluminum chloride hexahydrate are used to treat hyperhidrosis, a condition involving excessive sweating. It is also employed in deodorants, antiperspirant preparations, dyeing fabrics, refining crude oil, textile finishing, manufacturing parchment paper, preserving the wood and disinfecting stables. It also finds use as a reagent in organic synthesis. Aluminum chloride hexahydrate is also useful in water treatment process, medicine and cosmetic products.

PreparationAluminum chloride hexahydrate is prepared by dissolving Al(OH)3 in conc. HCl and passing gaseous HCl through the solution at 0°C. The precipitate is washed with diethyl ether and dried. Alternatively, it is prepared by hydrolyzing anhydrous AlCl3 in cold dilute HCl.
