Beschreibung
Zusammenfassung:	The present invention provides an improved process for the preparation of pharmaceutically acceptable Sodium 2-propylpentanoate 2-propylpentanoic acid (1:1) or Divalproex sodium. Novelty of the process resides in single step synthesis of valproic acid. The invention provides less energy intensive,process to produce valproic acid and produces Divalproex sodium of 1CH purity in shorter time and better yields.
