Aluminum Fluoride is added to molten aluminum oxide (Al O ) to improve conductivity of the metal to facilitate separation of the aluminum from the compound. 2 3 It can be used in the catalysis of organic compounds.
It is used to regulate and decrease the amount of fermentation during the production of alcohol. Catalysts are typically made of platinum, palladium, rhodium, and iridium, which are very expensive rare metals. Aluminum fluoride is a much cheaper option for a catalyst. An increase in the speed of a chemical reaction due to the presence of a catalyst Aluminum fluoride is toxic if it is directly inhaled or makes direct contact with the skin. Even though it is a fluoride compound, it should not be added to public water supplies, as it is toxic when ingested. Aluminum fluoride exists as a solid crystal, commonly as a hydrate, where seven water molecules surround every two aluminum fluoride molecules. It has a trigonal planar molecular shape with a bond angle of 120º.
