Polymer Supported Catalysts

Polystyrene-Aluminium Chloride: It is used to prepare Ethers from alcohols. Polystyrene AlCl3 is a useful catalyst for synthetic reactions which require both a dehydrating agent and a Lewis acid. Thus, acetals are obtained in good yield by the reaction of aldehyde, alcohol and polymeric AlCl3 in an organic inert solvent. Polymeric super acid catalysts: This polymeric super acid catalysts are obtained by aluminium chloride to Sulfonate Polystyrene.
