Aluminium chloride hexahydrate Chemical Properties,Usage,Production

Physical Properties

White or yellowish deliquescent powder; faint odor of HCl; density 2.40 g/cm3; soluble in water and polar organic solvents such as alcohol; aqueous solution acidic.

Uses

The 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.

Preparation

Aluminum 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.

Reactions

Decomposes to alumina when heated at 300°C;
2AlCl3 •6H2O →2Al2O3 + 6HCl + 9H2O
Reacts with caustic soda solution forming gelatinous precipitate of aluminum hydroxide (hydrous aluminum oxide); yields aluminum monobasic stearate, Al(OH)2[OOC(CH2)16CH3] when its solution is mixed with a solution of sodium stearate.

Chemical Properties

white to pale yellow crystalline solid

Uses

The 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.

Uses

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

Uses

Pharmaceutical 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.

Definition

ChEBI: Aluminium trichloride hexahydrate is a hydrate. It contains an aluminium trichloride.

Indications

Aluminum chloride hexahydrate (6.25% Xerac A-C) is an effective antiperspirant that has also an antibacterial effect. It may be useful in cases of acne in which sweating is prominent or appears to be aggravating the disease, but its effects have not been well studied.
