Abstract: Nicotinic acid has been widely used in different fields as the important chemical and pharmaceutical intermediate.Compared with other traditional technology for production of nicotinic acid, one-step gas phase oxidation of 3-picoline has remarkable advantages of low cost, easy product separation, high product quality and few pollution.The oxidative reaction of 3-picoline on V2O5/TiO2 catalysts had rather high activity.Thus the paper reviews the recent research progress of oxidation 3-picoline to nicotinic acid on V2O5/TiO2 catalysts. It analyzed the surface structures of the catalysts by carrier and the influence factors from the preparation methods, loading content of V2O5, calcination temperature and time and doping additives. It also discussed the effects of interactions among various catalytic species, and the mechanism of the catalytic reaction. Defects of low reaction rate and selectivity, narrow temperature window and the heat of exothermic reaction were also explained. Finally, the application perspective and future development in the field of V2O5/TiO2 catalysts and the reactor design were explored.

摘要: 烟酸作为重要的化工和医药中间体广泛应用于不同领域.相较于传统工艺,3-甲基吡啶气相一步催化氧化合成烟酸的方法具有成本低、污染低、产品质量高等优点,展现出良好的应用前景.目前V2O5/TiO2系列催化剂在3-甲基吡啶的氧化反应中表现出了良好的氧化活性.本文主要分析了催化剂表面的VOx结构,并概述了载体、制备方法、负载量、焙烧过程和助剂掺杂对结构的影响,探讨催化剂中各组分之间的相互作用,根据相关文献推测3-甲基吡啶氧化的反应机理.但该类催化剂仍然存在反应速率和选择性较低、温度窗口窄、反应过程中放出的热量对催化剂的影响等一些技术问题.文章从催化剂的开发和反应器的设计两方面进行了展望.
