A simultaneously potentiometric titration method for determinating benzaldehyde and benzoic acid in electrosynthesis product is reported. The interferences from benzyl alcohol and toluene were examined. The determination method has advantages of high precision, good reproducibility, easiness in operation and rapidity. The RSD and recovery of benzaldehyde and benzoic acid in synthesis sample is 0.33%, 1.30% and 97.76%, 101.27%, repectively.
