Electro-organic Synthesis of 2-nitrobenzoic acid has been carried out by the electro oxidation of 2-nitrobenzaldehyde studied at different modified electrodes i.e. ruthenium oxide (RuO2) dopped on ebonex ,iridium oxide (IrO2) dopped on ebonex and lead oxide (PbO2) under acidic conditions using galvanostatic techniques. Isolated product was haracterized by T.L.C., usual laboratory qualitative tests and IR, NMR spectral analysis to be 2-nitrobenzoic acid. Effect of different parameters like current density, temperature, depolarizer concentration and nature of anode material on yield percentage and current efficiency have been investigated. Number of electrons have also been calculated to confirm the isolated product to be 2-nitrobenzoic acid.
