Alkali metal fluoride dispersion and process for producing fluorine-containing organic compound using the same |
摘要 |
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.
