Abstract

Abstract: Amorphous Co-P-B catalysts with different Co/P and P/B molar ratios were prepared by chemical reduction method. The catalysts were characterized with XRD, ICP-Mass and N2 adsorption-desorption isotherm. The catalysts were evaluated in the hydroformylation of 1-octene under the reaction conditions of 5.0 MPa and 120 ℃. The results showed that amorphous Co-P-B catalysts exhibited relatively high activity and selectivity in the hydroformylation of 1-octene. The molar ratios of Co/P and P/B, amorphous property and surface area affected the activity and selectivity of the Co-P-B catalysts, and the conversion and selectivity were enhanced by adding appropriate amount of P. Over the Co-P-B catalyst(Co 85.4%, P 3.3%, molar fraction), 97.2% conversion of 1-octene and 99.5% selectivity of C9-aldehyde were obtained under the reaction conditions employed in this study.
