General description

Aluminum chloride and Aluminum hydroxide are used for the staining of Mucicarmine.

Application

Aluminium chloride (AlCl3) can be used as a Lewis acid catalyst:
  • In Friedel−Crafts reactions.[1][2]
  • In the carboxymethylation of alcohols in the presence of dimethyl carbonate.[3]
  • To synthesize a porous organic polymer with hydroxyquinoline via polymerization reaction between perylene, 8-hydroxyquinoline, and chloroform.[4]

It is also used in combination with NaI or KI in acetonitrile for varieties organic transformations such as Claisen rearrangement of aromatic alcohols, selective dealkylation aliphatic methyl ether, and chemoselective C−O bond cleavage of esters, acetals, ethers, and oxathiolanes.[5]
