A core-shell Ni/SiO2@TiO2 catalyst for highly selective one-step synthesis of 2-propylheptanol from n-pentanal
文献摘要：
One-step synthesis of 2-propylheptanol(2-PH)from n-pentanal via a reaction integration of n-pentanal self-condensation and successive hydrogenation is of great significance for it can simplify process flow and reduce energy consumption.The key to promotion of 2-PH selectivity is to enhance the competitive-ness of n-pentanal self-condensation with respect to its direct hydrogenation.For this purpose,a core-shell structured Ni/SiO2@TiO2 catalyst was designed and prepared.With the precise architecture of this core-shell structured catalyst,n-pentanal can be firstly in contact with TiO2 to 2-propyl-2-heptenal(2-PHEA)while the direct hydrogenation to n-pentanol can be effectively inhibited,and then 2-PHEA dif-fuses into the core of Ni/SiO2 and is hydrogenated to 2-PH.The spatial threshold of the core-shell catalyst significantly enhanced its catalytic performance;a 2-PH selectivity of 77.9％was reached with a 100％n-pentanal conversion.The 2-PH selectivity is much higher than that obtained by employing Ni/TiO2 cata-lyst.Furthermore,the reaction kinetics of one-step synthesis of 2-PH from n-pentanal catalyzed by Ni/SiO2@TiO2 was studied and its kinetic model was established which is useful for reactor design and scale-up.
