Abstract
The purpose of optimization consists in establishing suitable values for the operational parameters of a process, in order to achieve the results of that process to the greatest possible advantages. These ideal operating conditions are known as the optimum. The process parameters are current density, temperature, concentration, electrode materials, flow rate, cell voltage, mixing and diaphragm and engineering quantities are like current efficiency, space-time yield, energy consumption, yield and conversion. There are several possible targets in optimization of process and the main aim is to get maximum yield, high current efficiency, high purity and minimum energy consumption for mediated electrochemical oxidation. Mediated electro oxidation or indirect electrosynthesis is a cyclic process involving electrochemical generation of cerium(IV) and uses that agent to effect a chemical reaction. Cerium(IV) has attracted attention in electroorganic synthesis for synthesis of aldehydes and quinones.
Keywords: optimization, parameters, mediated electro oxidation, current efficiency, yield, space-time yield.
