✦ Synopsis

The effect of pH on the distribution coefficients of maleic and fumaric acids on Dowex l-X8 (Cl-) anion-exchange resin has been investigated. From the dependence of the overall distribution coefficient on the pH of the solution, the ion-exchange selectivity coefficients for the monovalent and bivalent anions of maleic and fumaric acids have been calculated. The selectivity series observed follows the decreasing order of protonation constants.

The nuclear magnetic resonance spectra of the resin in various ionic forms have also been investigated qualitatively.

The electrolytic reduction of maleic and fumaric acids was studied with a rotating lead cathode. A current efficiency of 98 per cent with an assay yield of 95 per cent was obtained at a cathode current density of 20 A/dm 2. The choice of the cathode material is explained on the basis of the (~ poten
