| 摘 要： | 使用共沉淀法分别制得镁铝水滑石固载MnO4-、Cr2O72-催化剂HT-MnO4-、HT-Cr2O72-和IO4-柱撑型催化剂HT-IO4-,并在温和条件下用于以分子氧为氧化剂的醇类催化液相氧化反应,结果表明HT-MnO4-、HT-Cr2O72-催化剂可以在温和条件下实现醇类化合物(苯甲醇、对甲氧基苯甲醇、2-吡啶甲醇、肉桂醇、苯乙醇)的高选择性氧化转化。XRD表征给出水滑石经过MnO4-、Cr2O72-阴离子交换以后,X射线衍射峰中最强峰对应晶面的平均粒径减小,但结构仍然完整;XPS表征表明HT-MnO4-、HT-Cr2O72-中Mn、Cr的结合能较之KMnO4、K2Cr2O7中Mn、Cr的结合能有所降低。

| Abstract: | Mg-Al hydrotalcite-supported MnO4-,Cr2O72-and IO4-catalysts(named HT-MnO4-,HT-Cr2O72-and HT-IO4-,respectively) were prepared by coprecipitation method and subjected to liquid-phase oxidation of alcohols(benzyl alcohol,p-methoxybenzyl alcohol,cinnamon alcohol,and 2-phenylethyanol) in the presence of molecular oxygen under mild conditions.HT-MnO4-and HT-Cr2O72showed high catalytic activity for the oxidation of alcohols and had high selectivity to corresponding aldehydes.XRD indicated that the average particle... |
