甲基吡啶气相氨氧化V系催化剂研究进展

Development of Catalyst for Gas Phase Ammoxidation of Picolines to Cyanopyridines

综述了国内外甲基吡啶气相氨氧化制氰基吡啶V系催化剂的研究进展。在甲基吡啶气相氨氧化中,V系催化剂可以以非负载和负载两种形式起作用。负载型V系催化剂因其机械强度、热稳定性和寿命更优异而得到更加广泛的应用和研究。

This paper reviewed the development of V-contained catalysts for gas phase ammoxidation of picolines to corresponding cyanopyridines. V-oxide catalysts could been used in ammoxidation of picolines by unsurported or supported V-oxide. The supported V-oxide had excellence mechanical intensity, thermal, stability and life, they had been studied and used widely in the industry.
