Electrochemical oxidation of p-t-butyltoluene (TBT) to p-t-butylbenzaldehyde (TBBZ) was carried out in a filterpress cell. Electrolysis was carried out galvanostatically at PbO2 anode and Metcote ES1 cathode using sulfuric acid as electrolyte. The effect of different parameters such as acid concentration and current density was studied in order to optimize the yield of TBBZ. Electrolysis conditions were optimized for maximum current efficiency for TBBZ production. At optimum conditions at 41% conversion, a current efficiency of 73% with aldehyde to acid mole ratio of 13 was obtained.
