英文摘要: Hydroformylation of 1-hexene over a series of silica supported noble metal catalysts, HRhCO ( TPP)(3), HRhCO (TPPTS)(3)/SiO2 and TPPTS-Rh/SiO2 catalyst were investigated. The results show that the selectivity towards aldehydes and the ratio of liner to branched aldehyde (n/b) over Rh-TPPTS/SiO2 catalyst are near to those of HRhCO ( TPPTS)(3)/SiO2, but much higher than to those of Rh/SiO2. Under the higher pressure of 7.0 MPa, the TOF of aldehydes on Rh-TPPTS/SiO2 catalyst increase greatly up to 0. 0692 S-1. A possible of catalyst model of Ligands containing lone-pair electron tightly chemically connected to the highly dispersed Rh particles and formation of supported aqueous-film heterogeneous catalyst possessing of homogeneous catalytic performance has been tentatively proposed.
