Lithium hexafluoroarsenate of high purity is prepared by a metathetical rtion between potassium hexafluoroarsenate and lithium perchlorate in an inert organic solvent such as methyl formate. The potassium perchlorate produced is insoluble in the solvent and can be readily separated from the lithium hexafluoroarsenate which is soluble in the solvent.
