Pd/C催化剂上烯酮的选择性加氢反应
Selective Hydrogenation of Alkenone to the Corresponding Saturated Ketone over Carbon Supported Palladium Catalysts
摘要
Abstract
In this paper, effects of palladium loading, catalyst granularity, pretreatment method of support and reaction temperature on the hydrogenation reduction of 6,10,14-trimethyl-13-ene-2-pentadecanone (FA-4H) over Pd/C catalyst were investigated under solvent-free condition in a batch reactor. The experimental results show that the activity of Pd/C catalyst for FA-4H hydrogenation increases with increasing the palladium loading;99.3%~99.5%selectivity towards hexahydrofarnesylacetone (PA) is obtained when Pd loading is in the range of 0.5%~3.0%(wt). The catalyst with smaller granularity possesses shorter pore channel which would contribute to deducing the retention time of PA inside the pore channel of catalyst particles, and to some extent preventing the over-hydrogenation of C=O double bond in the FA-4H. In addition, pretreatment of active carbon support with nitric acid or aqueous ammonia solution, and low reaction temperature are also favorable for decreasing the content of byproducts such as 6,10,14-trimethyl-13-ene-2-pentadecanol(FA-alcohol) and 6,10,14-trimethyl-2-pentadecanol(PA-alcohol) and improving correspondingly the selectivity towards PA.关键词
