Aluminium chloride hexahydrate Usage And Synthesis
  • Physical PropertiesWhite 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.
  • 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.
  • 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.
  • ReactionsDecomposes 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 Propertieswhite to pale yellow crystalline solid
  • 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
  • IndicationsAluminum 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.
