The carboxymethyl cellulose ( CMC )-polyvinyl alcohol ( PVA )/chitosan ( CS )-PVA bipolar membrane ( BPM) was modified by nano silicon dioxide. Then the modified BPM was used as electrolytic cell septum to synthesize succinic acid and p-chlorobenzaldehyde. The results showed that the optimal preparation conditions were as following:current density was 60 mA/cm2 , sulfuric acid concentration in the cathode chamber was 1. 0 mol/L,the molar ratio of p-chlorotoluene to Mn3+ was 4∶1.
