Dibutylphthalate has been prepared<i> </i>via esterification reaction in the presence of some solid acidic catalysts. Transition metal polyoxometalates with Keggin (K<sub>3</sub>[PMo<sub>6</sub>W<sub>6</sub>O<sub>40</sub>], K<sub>3</sub>[PMo<sub>12</sub>O<sub>40</sub>], K<sub>4</sub>[SiMo<sub>12</sub>O<sub>40</sub>], K<sub>4</sub>[SiW<sub>12</sub>O<sub>40</sub>], Na<sub>7</sub>[PW<sub>11</sub>O<sub>39</sub>]), Wells-Dawson (K<sub>6</sub>[P<sub>2</sub>W<sub>18</sub>O<sub>62</sub>]), and Preyssler structures (K<sub>14</sub>[NaP<sub>5</sub>W<sub>30</sub>O<sub>110</sub>]) have been synthesized and characterized. The reactivity of these catalysts has been studied for the preparation of dibutylphtalate by esterification reaction of phthalic anhydride and 1-butanol. Among the various acidic catalyst used, K<sub>3</sub>[PMo<sub>6</sub>W<sub>6</sub>O<sub>40</sub>] showed the best reactivity and efficiency compared to other catalysts. |
