Abstract

PURPOSE:To efficiently produce a high purity LiF complex salt useful as the electrolyte of a cell, a catalyst, etc., by releasing hydrofluoric acid from acidic LiF and allowing the resulting porous LiF to react with the fluoride of a group III, IV or V element of the periodic table. CONSTITUTION:Acidic LiF obtd. by the reaction of LiF with hydrofluoric acid is heated to 60-700 deg.C to release hydrofluoric acid from the acidic LiF. The resulting porous LiF is allowed to react with the fluoride of a group III, IV or V element of the periodic table, e.g., BF at 50-200 deg.C to obtain an LiF complex salt contg. 0.1-10wt.% unreacted LiF. This unreacted LiF is removed by washing the complex salt with an org. solvent such as 1,2-dimethoxyethane. The amt. of the org. solvent used is twice-ten-odd times the amt. of the complex salt.
