Lithium perchlorate

CAS number : 7791-03-9

Molecular weight :106.39

Molecular formula/chemical symbol :LiClO4

Description :

Lithium perchlorate is the inorganic compound with the formula LiClO4. This white or colourless crystalline salt is noteworthy for its high solubility in many solvents. It exists both in anhydrous form and as a trihydrate.

Lithium perchlorate can be manufactured by reaction of sodium perchlorate with lithium chloride. It can be also prepared by electrolysis of lithium chlorate at 200 mA/cm? at temperatures above 20 °C.

Perchlorates often give explosive mixtures with organic compounds.

USES :

Lithium perchlorate is used as a source of oxygen in some chemical oxygen generators.

Lithium perchlorate is also used as an inert electrolyte in lithium batteries.

Concentrated solutions of lithium perchlorate (4.5 mol/l) are used as a chaotropic agent to denature proteins.

Lithium perchlorate is also used as a co-catalyst in the coupling of α,β-unsaturated carbonyls with aldehydes, also known as the Baylis-Hillman reaction.
