Abstract

Conversion of dipotassium malate to malic acid was carried out through conventional electrodialysis and through electrolysis in combination with cation-exchange membranes. For the first method, hydrochloric acid was added to dipotassium malate, and the potassium chloride that formed was removed by electrodialysis. For the second method, H+ generated at the anode during electrolysis of water migrated through cation-exchange membranes and converted dipotassium malate to malic acid.
