Spécifications des grades

Maximum level of impurities: Insoluble matter 0.005%, pH of a 5% solution 6.0-7.5 at 25°, Cl 0.003%, SO<sub>4</sub> 0.001%, Heavy Metals (ICP-OES) 5ppm, Fe 5ppm

Applications

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.

Notes

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