چکیده:

p-Amino phenol is an important intermediate in the preparations of analgesic and antipyretic drugs.[1] Various methods have been reported to synthesize p-amino phenol. In order to meet the growing demand for p-aminophenol, the direct catalytic hydrogenation of p-nitro phenol to p-aminophenol is becoming important, [2 ] because this could be an efficient and greener route. Raney nickel, nano sized nickel and several noble metals have been used as catalysts for this reaction. [ 3 ] Due tolower price and higher catalytic activity, supported nickel catalysts, such as Ni/Al2O3 catalyst , is widely used in various hydrogenation reactions. [ 4 ] In this work, we have attempted to perform the catalytic hydrogenation of p-nitro phenol to p-amino phenol using nano Pt/ SnO2 catalyst because there has been no work reported . [ 6 ] The results were compared with those obtained in the presence of nano nickel catalysts
