실험 절차

Difluorophosphoric acid (reagent, produced by Fluorochem Ltd.) (18.6 g) was weighed into a 250 ml-volume PFA vessel, and 4.1 g of lithium hexafluorophosphate (reagent, produced by Stella Chemifa Corporation) was added. Furthermore, 13.5 g of potassium chloride (reagent, produced by Wako Pure Chemical Industries, Ltd.) and 20.0 g of dimethyl carbonate were 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 potassium 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 91% in terms of the relative area.
