| 英文摘要 | a ligand (triphenyl phosphine, pph(3))-modified heterogeneous pph(3)-rh(co)/sba-15 catalyst and supported wilkinson complex hrh(co)(pph(3))(3)/sba-15 catalyst were prepared and examined in the hydroformylation of propene. heterogeneous pph(3)-rh(co)/sba-15 catalyst showed much higher activity and stability in this reaction. multimuclear (1)h, (29)si, (31)p, and (17)o mas nmr and two-dimensional (17)o mq mas nmr together with xrd and n(2) adsorption were employed to study the local structures of these two catalysts. quantitative (1)h and (29)si mas nmr and qualitative one- and two-dimensional (17)o mas and mq mas nmr indicate that in the presence of co the silanols on the surface of sba-15 can react with rhodium carbonyls to form the si-o-rh bonds at the interface between the catalyst and the support. it mas nmr spectra demonstrate a similar wilkinson complex structure is produced on the heterogeneous pph(3)-ph(co)/sba-15 catalyst. the formation of si-o-rh bonds at the interface may immobilize the rh complex during the long reaction. these may be correlated to the higher performances of heterogeneous pph(3)-rh(co)/sba-15 catalyst in propene hydroformylation. |
