摘要: 研究了钒取代钼杂多化合物对异丁酸氧化脱氢生成甲基丙烯酸的催化行为。用IR、DTA方法研究了钒对催化剂稳定性、酸性的影响。ESR和循环伏安研究结果表明,钒不仅改变了催化剂的物化性质,而且参与了反应,成为新的催化活性中心。

关键词: 氧化脱氢, 异丁酸, 杂多化合物,

Abstract: The catalytic behaviour of oxidative dehydrogenation of isobutyl acid to methylacrylic acid on the V-substituted molybdenum heteropoly compounds was studied.The effect of vanadium on the stability and acidic property of the catalyst was also investigated by means of IRand DTA, The ESRresults show that the vanadium not only changed physical-chemical properties of the catalyst, but also participated in the reaction, becoming a new catalytic site.

Key words: Oxidative dehydrogenation, Isobutyl acid, Heteropoly compound, Vanadium
