    摘要: A method for manufacturing a phosphate, which includes reacting, in a solvent, an organophosphate represented by the following formula (2) and an alkali metal hydroxide in an amount of 1.01 mole equivalents or more relative to the organophosphate to provide a composition containing a phosphate represented by the following formula (1), the alkali metal hydroxide, and the solvent; and adding hydrogen fluoride to the composition to neutralize the composition and to precipitate an alkali metal fluoride, thereby providing a composition containing the precipitated alkali metal fluoride, the phosphate represented by the formula (1), and the solvent. The formula (1) is (R11O)(R12O)PO2M, where R11, R12 and M are as defined herein. The formula (2) is (R21O)(R22O)(R23O)PO, where R21, R22, and R23 are as defined herein.
