Abstract

A preparative technique for the electroreduction of aromatic nitro compounds using a copper cathode, a lead anode and a porous pot diaphragm with 30–40% H2SO4 as the anolyte and 30–40% H2SO4 containing 2–3% Ti(SO4)2 as the catholyte is reported. Nitrobenzene, dinitrobenzenes, nitrotoluenes, phenols, phenetoles and nitrochlorobenzenes have been reduced by this method. Slightly modified techniques were employed for some compounds such as 2-nitro-m-xylene. The results of some pilot plant studies are also reported. The studies indicate that on smaller scales this technique may be competitive with metal/acid systems with the additional advantage of less pollution problems.
