Lanthanum chloride (LaCl3) is a chemical compound. It is used as a mild Lewis acid to perform chemical reactions that usually require acidic conditions, such as converting aldehydes to acetals, under nearly neutral conditions.
The lanthanide ions are 9 coordinate in the trichloride.
The compound has been identified as a catalyst for the high pressure oxidative chlorination of methane to chloromethane with hydrochloric acid and oxygen[1]. Interestingly in this process the +3 oxidation state of lanthanum remains unchanged.
[edit] Uses
Lanthanum chloride can be used to remove phosphates in swimming pools, which helps prevent algae growth. It is also used in biochemical research to block the activity of divalent cation channels, mainly calcium channels.
