摘要
合成了磷钨杂多化合物，考察了其对十八醇经过氧化氢催化氧化制十八酸的反应活性，探讨了温度、催化剂用量、反应时间以及Ｈ２Ｏ２与底物的摩尔比等一系列条件对反应的影响，确定了最佳反应条件．通过ＩＲ，ＩＣＰ，ＵＶ和ＮＭＲ等技术对催化剂进行了表征，考察了反应前后催化剂的变化情况。
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.
