Synthesis of highly dispersed cobalt catalyst for hydroformylation of 1-hexene†
Abstract
Highly dispersed Co/SiO2 catalysts were prepared using an ethylene glycol (EG) modified silica support. The modified SiO2 support significantly promoted the dispersion of supported cobalt and adding a small amount of Ru increased the reducibility of the highly dispersed cobalt oxide. The Co–Ru/SiO2 (EG) catalyst exhibited 3 times higher 1-hexene conversion and 18 times higher heptanal yield than the conventional Co/SiO2 catalyst.
