EUClass = not listedLanthanum chloride (LaCl3) is a
chemical compound . It is used as a mildLewis acid to performchemical reaction s that usually require acidic conditions, such as convertingaldehyde s toacetal s, 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 ofmethane tochloromethane withhydrochloric acid and oxygencite journal |author=Podkolzin SG, Stangland EE, Jones ME, Peringer E, Lercher JA |title=Methyl chloride production from methane over lanthanum-based catalysts |journal=J. Am. Chem. Soc. |volume=129 |issue=9 |pages=2569–76 |year=2007 |pmid=17295483 |doi=10.1021/ja066913w] . Interestingly in this process the +3oxidation state of lanthanum remains unchanged.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 , mainlycalcium channels .References
