Abstract

A process in which an electrochemical cell is used to simultaneously conduct a product synthesis and purification while also regenerating conductive material. The improved process is applied to an electrochemical synthesis which is conducted by electrolyzing a working electrolyte into which ions selectively flow, as through an ion-exchange membrane, from a counter electrolyte. The improvement comprises the step of purifying a previously electrolyzed working electrolyte by including it in or as a counter electrolyte in a subsequent synthesis.
