| Abstract: | The present disclosure relates to process for synthesis of p-aminophenol (PAP). More particularly, the disclosure relates to improved process for synthesis of p-aminophenol (PAP). More particularly, the present disclosure relates to provide complete conversion of p- chloronitrobenzene (PCNB) to sodium nitrophenolate followed by catalytic hydrogenation of sodium nitrophenolate to sodium aminophenolate further its acidification giving p-aminophenol which is widely used in the production of paracetamol & dyestuffs. The productivity of process is increased and water consumption is reduced and overall plant footprint required is less in this process. |
