氨基吡啶氢化反应中不同贵金属催化剂协同作用的影响

Study on the Synergistic Effect of Different Noble Metal Catalyst in the Hydrogenation of Aminopyridine

贵金属催化剂以其高效、绿色环保等优点备受人们的关注,那么如何在此基础上提高其催化活性,选择性,延长催化剂的使用寿命一直是研究的热点,本文中研究了在氨基吡啶加氢制备氨基哌啶的过程中,在不同溶剂的条件下,不同载体负载不同贵金属之间的协同催化作用。相对于单金属催化剂,在某些方面双金属催化剂的加氢活性更高选择性更好。

Precious metal catalysts have attracted people's attention because of their high efficiency,environmental protection and other advantages.So on this basis,how to improve their catalytic activity,selectivity,and extend the service life of catalysts has always been a hot research.In the process of preparing aminopiperidine,under different solvent conditions,different carriers support different precious metals for synergistic catalysis.Compared with the single metal catalyst,the hydrogenation activity of the bimetallic catalyst is higher and the selectivity is better in some aspects.
