Description
Lithium hexafluorophosphate is an inorganic compound with the formula LiPF6. This white crystalline powder is used in commercial secondary batteries, an application that exploits its high solubility in nonpolar solvents. Specifically, solutions of lithium hexafluorophosphate in propylene carbonate with dimethoxyethane serves as an electrolyte in lithium batteries. This application also exploits the inertness of the hexafluorophosphate anion toward strong reducing agents, such as lithium metal.
LiPF6 also catalyses the tetrahydropyranylation of tertiary alcohols.
Keywords: Phosphate
USES
