    • Typical esterification procedure: In a typical experiment, esterification of phenylacetic acid (5 mmol, 0.68g) and 1-butanol (10 mmol, ∼1 ml) was carried out in a 100 ml round bottom flask with 10 M0l% of AlPW12 O40 powder. The reaction mixture was stirred at 75-80°C for 0.3h. Ethyl acetate (100 ml) was added to the reaction mixture, filtered and washed with ethyl acetate to recover the catalyst. The solvent and the unreacted butanol were evaporated off. The pure ester was obtained in 96% yield (1.84g) and identified by its IR, 1H NMR, and 13C NMR spectral data.
