| 摘 要： | 合成了Dawson型杂多酸盐Co2(Cpyr)4P2Mo16V2O62(Cpyr为十六烷基吡啶),并将其应用到乙苯氧化合成苯乙酮的反应中。建立了乙苯-Co2(Cpyr)4P2Mo16V2O62-乙酸-叔丁基过氧化氢(TBHP)催化氧化体系,并考察了溶剂种类及用量、催化剂用量、氧化剂用量、反应时间、反应温度等因素对乙苯氧化反应的影响。实验结果表明,乙酸为最佳溶剂,在优化反应条件(乙苯25mmol,乙酸10mL,Co2(Cpyr)4P2Mo16V2O62催化剂0.1mmol,n(乙苯)∶n(TBHP)=0.25,反应温度80℃,反应时间8h)下,乙苯转化率达到80.9%,苯乙酮收率达到73.2%。
