Abstract
Lithium chloride containing small amounts of inorganic and/or organic impurities is purified by heating the lithium chloride above about 200.degree. C., cooling the compound to ambient temperatures and extracting it with isopropanol, separating the liquid and solid phases, removing the isopropanol and recovering lithium chloride of high purity.
