合成了一系列钒取代在不同位置的杂多化合物, 考察了它们在环己烷催化氧化反应中的活性及其过氧化氢的分解情况, 发现钒的配位环境是影响反应活性的重要因素. 其中以H4PMo11VO40为代表的钒在配位原子位置上的磷钼钒酸, 不但显示了很好的催化环己烷氧化反应的活性, 而且H2O2的分解反应同时也得到了较好的抑制.

关键词: 含钒杂多化合物, 环己烷, 氧化反应

Some vanadium-contained compounds were prepared and characterized. We investigated their activity on the oxidation of cyclohexane and the decomposition of H2O2 and found that the coordinate surrounding of vanadium affect the activity of reaction strongly. When we use vanadium-substituted heteropoly compounds as catalyst, the decomposition of H2O2 can be restrained. Especially when vanadium was on the coordination site, such as H4PMo11VO40, the catalyst showed excellent activity for the oxidation of cyclohexane with low speed of the decomposition of H2O2.

Key words: vanadium-contained compound, cyclohexane, oxidation
