Abstract
p-Anisidine is an important dye and a pharmaceutical intermediate.Synthesis of p-Anisidine was studied by reducing p-Nitro Anisole with hydrazine hydrate in the presence of Pd/C catalyst.The results show that: for 0.05 mol p-Nitro anisole,the reaction medium is isopropanol,the temperature 70℃,the mole scale n(p-Nitro anisole)∶n(hydrazine hydrate)=1∶4,the reaction time 130 min and the yield 88.45%.The structure of the product is certified by way of melting point,elementary analysis and IR.
