POLAROGRAPHIC HALF-WAVE POTENTIALS OF SOME 1,4-NAPHTHOQUINONES

Abstract

The half-wave potentials for the reduction of 103 substituted 1,4-naphthoquinones were measured in 75% v/v aqueous ethanol containing buffer components. In general, if two constants were assigned, one characteristic of monosubstitution and the other characteristic of disubstitution, it was possible, by assuming additivity of the constants, to predict the half-wave potentials of the compounds within the experimental accuracy of the polarographic method.
