    • An alkali metal fluoride dispersion of an alkali metal fluoride and an aprotic organic solvent is obtainable by (A) separating a liquid phase from an alkali metal fluoride dispersion comprising an alcohol solvent and an alkali metal fluoride, and mixing the separated liquid phase with an aprotic organic solvent having a boiling point of 85° C. or higher at normal pressure; (B) obtaining a mixture containing the alkali metal fluoride by (b1) concentrating the mixture containing the alkali metal fluoride to obtain a concentrated fraction and a concentrated residue; (b2) mixing a residue of the alkali metal fluoride dispersion with the concentrated fraction obtained in (b1); and (b3) separating a liquid phase from the mixture containing an alkali metal fluoride obtained in (b2) and mixing the separated liquid phase with the concentrated residue; and (C) removing the alcohol solvent from the mixture containing the alkali metal fluoride.
    • 碱金属氟化物和非质子性有机溶剂的碱金属氟化物分散体可以通过(A)从包含醇溶剂和碱金属氟化物的碱金属氟化物分散液中分离液相,并将分离的液相与非质子 常压下沸点为85℃以上的有机溶剂; (B)通过(b1)浓缩含有碱金属氟化物的混合物得到含有碱金属氟化物的混合物,得到浓缩馏分和浓缩残渣; (b2)将碱金属氟化物分散体的残渣与(b1)中得到的浓缩馏分混合; 和(b3)从含有(b2)中得到的碱金属氟化物的混合物中分离液相并将分离的液相与浓缩残余物混合; 和(C)从含有碱金属氟化物的混合物中除去醇溶剂。
