Sodium hexafluorophosphate Usage And Synthesis

Chemical Properties

White solid, sensitive to air and carbon dioxide, highly soluble in water, decomposes at high temperatures.

Uses

Sodium hexafluorophosphate is used as an ion pairing agent for the determination of cobalt(II) in water samples. It is used as an important raw material in the preparation of 2-chloro-1,3-bis(dimethylamino)trimethinium hexafluorophosphate.

Application

Sodium hexafluorophosphate is a kind of high purity battery grade material, used as an electrolyte in research for sodium ion batteries.

Definition

ChEBI: Sodium hexafluorophosphate is an inorganic sodium salt having hexafluorophosphate(1-) as the counterion. It is an electrolyte used in sodium-ion batteries. It contains a hexafluorophosphate(1-).

Preparation

Prepared by slowly adding PCl5 dropwise to an aqueous HF solution containing NaCl.

Purification Methods

Recrystallise it from acetonitrile and dry it in a vacuum for 2days at room temperature. It is an irritant and is hygroscopic. [Delville et al. J Am Chem Soc 109 7293 1987.]
