Aluminium chloride hexahydrate Usage And Synthesis

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.
