Aluminum chloride
Aluminum chloride (CAS: 7446-70-0) is a strong Lewis acid with the molecular formula AlCl₃ and a molecular weight of 133.34 g/mol. It is a highly reactive inorganic compound, primarily utilised as a catalyst in organic synthesis, particularly in Friedel-Crafts reactions. Its potent dehydrating properties also find application in various chemical processes and material science research.

Catalysis in Organic Synthesis
Anhydrous aluminum chloride is a widely employed Lewis acid catalyst for Friedel-Crafts alkylation and acylation reactions. It facilitates the formation of carbon-carbon bonds, crucial in the synthesis of numerous organic compounds.
Dehydrating Agent
Its strong affinity for water makes aluminum chloride an effective dehydrating agent in certain chemical processes. It is used to remove water molecules from organic compounds or reaction mixtures.
Petroleum Refining
Aluminum chloride acts as a catalyst in the polymerisation of olefins and the production of lubricating oils and greases within the petroleum industry.
Material Science
Utilised in the development of new materials, including its role as a dopant in semiconductor research and in the creation of specialised metal and ceramic composites.
