Abstract:
A process for the purification of fluoroalkanesulfonate salt comprising (a) contacting a mixture of said salt and an inorganic salt contaminant with a solvent to selectively dissolve said fluoroalkanesulfonate salt in solution, and (b) isolating the solution, to yield a fluoroalkanesulfonate salt containing less than 500 micrograms of inorganic salt contaminant per gram of fluoroalkanesulfonate salt, or containing less than a maximum of 0.3% by weight of individual solvent.
