Acetylation of p-Aminophenol by Preyssler's anion [NaP₅W₃₀O₁₁₀]^14-, [NaP₅ W₂₉MoO₁₁₀]^14- with green condition at room temperature

Synthesis of acetaminophen at green condition and room temperature in the presence of the Preyssler type heteropolyacids has been investigated in order to contribute toward clean technology, which is the most important need of the society. All of the catalysts are recyclable and reusable.
