Procedure

Tartaric acid (15.0 g, 0.1 mole) is dissolved in 40 ml. water and treated with lithium hydroxide (8.4 g, 0.2 mole). The resulting solution is evaporated to a small volume under reduced pressure and the residue is treated with p-dioxane. The resulting precipitate is filtered and dried under vacuum to give the di-lithium tartarate (17.7 g).
