    摘要： A process for preparing difluorophosphate comprising reacting difluorophosphoric acid with at least one salt, as a raw material, selected from a halide salt, a carbonate, a phosphate, a hydroxide and an oxide of an alkali metal, an alkaline earth metal or an onium in the difluoraphosphoric acid, then separating a precipitate from the difluorophosphoric acid by solid-liquid separation, the precipitate being precipitated by crystallization operation in the difluorophosphoric acid, and removing the difluorophosphoric acid contained in the precipitate by distillation to obtain difluorophosphate.
