Abstract
Reduction of p-nitrophenol (PNP) to p-aminophenol (PAP) has been carri ed out over supported nickel and unpromoted and promoted Raney nickel catalysts at 110 degrees C and hydrogen pressures at 200 psig. Excelle nt conversions ranging from. 85% to 93% have been obtained with these catalysts after optimizing the process parameters. Nickel catalysts pr ovided attractive alternate substitute to conventional commercial Fe d egrees/H+ catalysts which pose stupendous environmental problems.
