Abstract

Aromatic nitration is one of the most important unit processes in synthetic organic chemistry and in the chemical industry. Aromatic nitrates such as nitro-phenols are important precursors for the production of dyestuffs, pharmaceuticals, agrochemicals, explosives, plastics, and other industrially important products. Conventional processes are commonly lead to mixtures of regioisomers and are not environment friendly. Recent advances in the synthesis of nitro-aromates by green chemistry approaches have been minimized the production of chemical waste, practical yield of an aromatic nitrated product increased by using green procedure over conventional procedure. Practical yield was found to be 66.5% in case of green synthetic approach where as in case of conventional process it was found to be 41.87%. Likewise green chemistry approach is superior over conventional procedure.
