Reaction Steps

Difluorophosphoric acid (reagent, produced by Fluorochem Ltd.) (18.3 g) was weighed into a 250 ml-volume PFA vessel, and 4.0 g of lithium hexafluorophosphate (reagent, produced by Stella Chemifa Corporation) was added. Furthermore, 10.4 g of sodium chloride (reagent, produced by Wako Pure Chemical Industries, Ltd.) was added, and the mixture was stirred for 1 hour under nitrogen flow and after heating at 130° C. for 17 hours, cooled to room temperature to obtain a mixed crystal of sodium difluorophosphate and lithium difluorophosphate. Anion analysis was performed in the same manner as in Example 2-6, as a result, the obtained difluorophosphate ion was 93% in terms of the relative area.
