Versuchsvorschrift

Surprisingly, the inventors have discovered that a heretofore unknown valproate salt, magnesium valproate hydrate, a white solid having the molecular formula C16H30O4Mg.x H2O, is recovered in high yields from an alcoholic solution of magnesium valproate by adding a polar, non-oxygen-containing organic solvent having a boiling point of about 130° C. or lower in a volume sufficient to reduce the solubility of the magnesium valproate in the resulting reaction mixture to less than about 0.01 g/mL. The polar, non-oxygen-containing organic solvent is acetonitrile, propionitrile, butyronitrile, or isobutyronitrile. Acetonitrile is most preferred.
