| Abstract | ||
| THE LIQUID-PHASE catalytic hydrogenation of p-nitrophenol to ……p-aminophenol was studied over kaolin supported nano-nickel catalysts prepared by chemical reduction by hydrazine hydrate. It was found that the 5% Ni-K catalyst has a superior catalytic activity corresponding to the other nickel contents, and hence it was chosen for determining the optimum conditions of such reaction. The effect of catalyst loading, p-nitrophenol concentration, NaOH and NH4OH concentrations on the catalytic activity of nano-nickel catalyst was investigated at 80oC. It was assessed that the catalytic efficiency of the catalyst was enhanced considerably by changing in NaOH and NH4OH concentrations during hydrogenation reaction. | ||
