The successful formation of the Wells-Dawson HPAs was confirmed by FT-IR and ICP-AES analyses.

The Wells-Dawson HPA catalysts were applied to the vapor-phase oxidation of methacrolein and benzyl alcohol. The reduction potential, conversion of methacrolein, and conversion of benzyl alcohol showed volcano-shaped curves with respect to vanadium substitution, and decreased in the order of H<SUB>8</SUB>P<SUB>2</SUB>Mo<SUB>16</SUB>V<SUB>2</SUB>O<SUB>62</SUB> &#62; H<SUB>7</SUB>P<SUB>2</SUB>Mo<SUB>17</SUB>V<SUB>1</SUB>O<SUB>62</SUB> &#62; H<SUB>9</SUB>P<SUB>2</SUB>Mo<SUB>15</SUB>V<SUB>3</SUB>O<SUB>62</SUB> &#62; H<SUB>6</SUB>P<SUB>2</SUB>Mo<SUB>18</SUB>O<SUB>62</SUB>. A correlation between reduction potential and catalytic activity clearly showed that the conversion was monotonically increased with increasing reduction potential of the HPA catalyst in both oxidation reactions.",
