| 摘 要： | 将杂多化合物与具有“氧溢流”效应的α－Ｓｂ２Ｏ４混合制备的催化剂，在叔丁醇一步选择氧化过程中，甲基丙烯酸为主要产物。经优化催化剂制备和反应条件后，甲基丙烯酸和甲基丙烯醛总收率在７５％以上，其中甲基丙烯酸收率达５０％，有工业应用前景。采用ＤＴＡ、ＩＲ、ＸＲＤ等方法对催化剂的组成与性能、物相结构进行了表征，考察了制备条件对催化剂活性的影响。

| Abstract: | A modified catalyst composed of heteropoly compound and α-Sb_2O_4 with oxygen spillover effect was used for the selective oxidation of t-butanol (isobutylene). Methacrylic acid (MAA) was the main product by one-step process. By optimizing the conditions of catalyst preparation and oxidation reaction, the yield of MAA is 50% and the total yield of MAA and methacrolein (MAL) is above 75%. The catalyst revealed a good potential application in industry. The physicochemical characterization of the catalysts (DTA, IR, and XRD) has been reported and the influence of preparation condition on catalytic activity has been examined in this paper. |
