Lanthanum(III) chloride
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.
Uses
Lanthanum chloride can be used to remove phosphates in swimming pools, which helps prevent algae growth.
