General description

Aluminum chloride hexahydrate is a nonflammable compound widely employed as a catalyst in organic synthesis. In addition to being extremely soluble in water, it is also soluble in alcohol, ether, glycerol, propylene glycol, and acetonitrile. It has many uses, including the refinement of crude oil, the production of deodorants and antiperspirant products, the dyeing of fabrics, textile finishing.

Application

Aluminum chloride hexahydrate is used as a catalyst:
  • In the synthesis of corresponding THP (tetrahydropyranylation) ether from alcohol or phenol, and 3,4-dihydro-2H-pyran (DHP).
  • In the direct esterification of levulinic acid and ethanol to produce ethyl levulinate.
  • In the synthesis of gem-dihydroperoxides from ketones and aldehydes.
