In situ Raman spectroscopy studies of the catalytic hydroformylation of propylene have been carried out over Co//2(CO)//6(PPh//3)//2 supported on alumina and on silica. A comparison in situ Raman spectroscopy study of the corresponding homogeneous liquid-phase reaction has also been carried out. The surface reaction intermediates identified spectroscopically in the heterogeneous reaction studies differed from one another for the two supported catalyst systems. The spectral data also indicated that these intermediates are not necessarily identical to those for the homogeneous liquid-phase hydroformylation reaction as catalyzed by Co//2(CO)//6(PPh//3)//2.
