Alternative Synthesis of Paracetamol and Aspirin under
Non-conventional Conditions

Abstract:

The paper deals with an alternative route for the synthesis of N-acetyl-p-aminophenol (paracetamol, PAR) and acetylsalicylic acid (aspirin, ASA) using principles of green chemistry, namely solvent-free synthesis combined with microwave-energy irradiation. The synthesis was carried out using salicylic acid and 4-aminophenol, acetic anhydride and no catalyst, under microwave irradiation. The yields were 92.4% for PAR and 81.6% for ASA. The compounds were identified by comparison with high-purity standards by the means of thin layer chromatography (TLC), melting point (m.p.) and FTIR spectroscopy. Keywords: paracetamol, aspirin, microwave irradiation, green chemistry, synthesis
