| Abstract: | The catalytic properties of the synthesized PW heteropoly compounds for the oxidation of octadecanol to octadecanoic acid were investigated. The effects of temperature, catalyst loading, reaction time and molar ratio of H2O2 to the substrate on the reaction were studied. Based upon the experimental results the optimal reaction conditions were suggested. IR, ICP, UVDRS and MAS NMR were employed to characterize the heteropoly compounds, particularly a comparison of catalyst before and after reaction was made. The structure of the active center for the oxidation reaction was discussed. |
