Electrochemical synthesis of valuable calcium-containing compounds from solutions of calcium chloride, a multi-tonnage industrial waste, was investigated. Electrochemical processes for the synthesis of calcium sugarate, carbon dioxide and calcium acetate by electrolysis of calcium nitrate and calcium chloride have been developed.
The work concerns the development of electrochemical technologies for utilization of wastes containing calcium chloride. Technologies for obtaining calcium saccharate and calcium dithionite from calcium chloride in diaphragm electrolyzer are developed. The main products of electrolysis: hydrogen and chlorine are of great value. The kinetic regularities of electrode reactions have been studied by taking volt-ampere curves. The optimal parameters of the processes have been established.
