摘要/Abstract

摘要： 以Dawson结构的磷钼钒杂多酸为催化剂、质量分数为30%的H₂O₂为氧化剂, 研究环己烷的催化氧化反应. 考察了钒含量、温度、催化剂用量、过氧化氢用量及反应时间对环己烷氧化反应的影响, 并将其结果与以相应的Keggin结构磷钼钒杂多酸为催化剂时得到的结果进行比较, 表明在相同反应条件下, Dawson结构的磷钼钒酸的催化活性明显高于相应的Keggin结构的磷钼钒酸的催化活性.

Abstract: A series of Dawsontype vanadiumsubstituted heteropoly acids was synthesized successfully. These compounds show an excellent activit y for the oxidation of cyclohexane with 30% H₂O₂ as oxidant. The reaction conditions, such as the number of the vanadium atom substituted in the heteropolya cids, amount of the catalyst, temperature, amount of H₂O₂ and reaction time were investigated in detail. The research results reveal that Dawsontype m olybdovanadophosphoric heteropolyacids exhibit better activities for the oxidation of cyclohexane compareable to Keggintype molybdovanadophosphoric heteropolyacids.

Key words: Dawsontype molybdovanadophosphoric heteropoly acid, cyclohexane, oxidation
