An improved process for the synthesis of paracetamol. p-aminophenol is acetylated in aqueous medium to produce a crude aqueous reaction mixture and paracetamol product is recovered by crystallization from an aqueous system comprising the reaction mixture. According to the improvement, paracetamol recovered by filtration and the filtrate containing acetic acid & dissolved paracetamol. The filtrate(as a solvent) as a required amount send to the reactor for paracetamol synthesis and excess amount filtrate store in a storage tank for distillation. According to that, required amount filtrate used as a solvent from 2nd batch to 12th batch, finally total filtrate goes to distillation to recovery acetic acid and distilled residue goes to another storage tank for neutralization and after filtration, the filtrate as inffluent goes the solar panel for evaporation and collected a small scale residue from solar panel goes to incineration.

Recovery, paracetamol, paracetamol synthesis, acetic acid, waste water.
