摘要:
The invention concerns the electrochemical preparation of dicarboxylic acids by subjecting an aqueous solution containing essentially the alkali-metal salt of a dicarboxylic acid of the general formula (I): HOOC-(CH2)n-COOH, in which n may be an integer from 1 to 8, or mixtures of such dicarboxylic acids, to an electrochemical treatment.
