Abstract: A phosphorus ligand-modified Rh/SiO2 catalyst (L-Rh/SiO2) has been develop ed for hydroformylation of internal olefins to linear aldehydes. This catalyst h as high activity and regioselectivity and can be separated easily by filtratio n after reaction in an autoclave. Moreover, the electronic and steric effects of phosphorus ligands on the catalytic performance of the L-Rh/SiO2 catalyst ha ve been investigated.

Key words: hydroformylation, heterogeneous catalyst, internal olefin, electronic effect, steric effect
