	abstract = {<p>Liquid phase esterification of benzyl alcohol (BA) to benzyl acetate (Peach fragrance) with an acetic acid (AA) has been investigated with 12-silicotungstic acid supported on zirconia embedded inside SBA-15 (STA/ZrO2/SBA- 15) as the catalyst. Catalysts were unambiguously characterized by XRD, N-2 adsorption-desorption, FF-IR pyridine adsorption techniques and the total amount of acidity of different STA loaded catalysts was estimated by TPD of NH3. The optimization of reaction conditions of an esterification of BA with AA was performed with 15 wt.\% STA/22.4 wt.\% ZrO2/SBA-15 calcined at 1123 K by varying catalyst concentration (1-10 wt.\% of reaction mixture); temperature, 353-383 K and AA:BA molar ratio as 0.5-3. The 15 wt.\% STA/22.4 wt.\% ZrO2/SBA-15 calcined at 1123 K was found to have the highest acidity and more active in the reaction. Under the optimized reaction conditions, the 15 wt.\% STA/22.4 wt.\%ZrO2/SBA-15 calcined at 1123 K gave 59\% BA conversion with selectivity for benzyl acetate as high as 96\% within 2 h of reaction time.
