Procedure
Furthermore, 709.5 g of ethylene carbonate (the moisture concentration: 7 ppm by weight) was added to 2,350.5 g of the resultant diethyl carbonate solution of lithium hexafluorophosphate to obtain a diethyl carbonate/ethylene carbonate solution of lithium hexafluorophosphate. The resultant solution contained 10 ppm by weight or less of an insoluble component, 10 ppm by weight or less of free acid and 10 ppm by weight or less of moisture.
