| 摘 要： | 以过氧化叔丁醇作为氧化剂,研究了醇类(苯甲醇、1-苯基乙醇和环己醇)在钒基催化剂上的氧化反应.制备了含苯磷二酚配体或吡嗪-2-羧酸酯配体的钒配合物,并运用傅里叶变换红外光谱、核磁共振谱、紫外-可见光谱及元素分析对其进行了表征.考察了溶剂对该类反应的影响.发现在甲苯溶剂中进行氧化反应时,苯甲醇被氧化成苯甲醛而不会被深度氧化为苯甲酸;而在乙腈溶剂中,苯甲醛和苯甲酸均有生成.此外,对不同钒磷氧化物的催化活性进行了比较,结果表明,在乙腈溶剂中的产品收率比在甲苯溶剂中高.

| Abstract: | Oxidation of various alcohols(benzyl alcohol,1-phenylethanol,and cyclohexanol) was studied over vanadium catalysts using tert-butyl hydroperoxide as an oxidant.Vanadium complexes with catecholate or pyrazine 2-carboxylate ligands were prepared and characterized by Fourier transform infrared spectroscopy,1H nuclear magnetic resonance spectroscopy,ultraviolet-visible spectroscopy,and elemental analysis.The effect of solvent was investigated.It was found that when the oxidation reaction was performed in toluene solvent,benzyl alcohol was oxidized to benzaldehyde without any overoxidation to benzoic acid;on the contrary,in acetonitrile solvent,both benzaldehyde and benzoic acid were formed.The catalytic activity of some vanadium phosphorus oxides was also compared, and the results showed that higher product yields were obtained when using acetonitrile as the solvent than using toluene. |
