According to the results of 31 P(1H)-NMR it was found that when water- soluble phosphine rhodium complex of HRh(CO)(TPPTS)3 was brought to SiO2, the decomplexation of part of phosphine ligands in the complex occurs due to the strong interaction of basic ligand TPPTS with acidic surface of silica-gel carrier, forming a surface complex.containing two phosphine ligands,i.e.,{Rh(CO)(TPPTS)2}.How ever, when using Na2CO3-pretreated SiO2,the twin signals at D= 44.8 for HRh(CO)(TPPTS)3 in the 31P(1H)2NMR was observed as dominant species in the supported catalyst under identical conditions. The hydroformylarion performance of SAPC is also affected by surface area and pore size of the supports.zh_CN
