The production of 1,2-dichloroethane and ethylene chlorohydrin by electrolysis of ethylene containing hydrochloric acid solutions was studied with a bench-scale continuous-flow undivided parallel-plate cell. The product distribution was independent of electrolyte flow rate and current density, but was significantly influenced by the chloride ion concentration. The cell current-voltage curves were found to be independent of electrolyte flow rate. Engineering models which included consideration of the chemical environment in the electrolysis zone were developed from fundamental principles of mass transport, ohmic resistance, and reaction kinetics. The models were verified by comparison with experimental findings, and were subsequently used to explore engineering aspects of scale-up and optimization. These models were incorporated with economic analyses to study the influence of design and operating parameters on the cost of 1,2-dichloroethane. A successive quadratic programming method was used to identify optimal operating conditions as well as the most sensitive parameters of the system.
