Applicazioni

Lithium perchlorate is used as an oxygen source for chemical oxygen generators, as it liberates oxygen at high temperatures. Excellent solubility of lithium perchlorate permits its use in Diels-Alder reactions. It is also employed in lithium-ion batteries as an electrolyte, and act as chaotropic agent to denature proteins. It is used in the Baylis-Hillman reaction as a catalyst in the coupling of alpha, beta-unsaturated carbonyl compounds with aldehydes.

Note

Hygroscopic in nature. Keep away from heat and sources of ignition. Keep the container tightly closed in a dry and well-ventilated place.
