Nitration of nitrobenzene at high concentrations of sulfuric acid

Abstract

Aromatic nitration by mixed acid a mixture of concentrated nitric and sulfuric acids is one of the most widely used reactions in the organic chemical industries Aromatic nitro compounds find wide use in the manufacture of dyes and explosives It is a heterogeneous liquid liquid reaction which occurs almost exclusively in the aqueous phase The organic compound diffuses into the aqueous mixed acid phase and reacts with the nitronium ion NO2 generated by the reaction between concentrated s
