    摘要: The invention relates to a method for producing compounds which contain at least one molecule valproic acid salt and at least one molecule valproic acid. The valproic acid salt represents alkali or alkaline earth salt. Valproic acid is directly converted with the calculated amount of the corresponding alkali carbonate or earth alkaline carbonate and/or the calculated amount of the corresponding alkali bicarbonate or earth alkaline bicarbonate without adding a solvent and at a temperature that is higher than the melting temperature of valproic acid.
