The selective functionalized MCM-41-based heterogeneous catalysts were applied toward the 1-octene hydroformylation. MCM-41 materials with amine and Rh complexes in the intra-pores show a higher selectivity for linear aldehydes. The mesopore, the steric bulky triphenylphosphine ligand greatly improved the selectivity of the less hindered linear aldehydes over the branched aldehyde. The active species involved in the hydroformylation has been studied by in situ FT-IR. The active species containing Rh(CO)2(PPh3)2 andHRh(CO)(Ph3P)3 were involved in the hydroformylation of 1-octene over the heterogeneous catalyst systems. |
