Abstract

Hydroformylation of olefins with CO and H2 is an attractive approach to synthesize value-added aldehydes. Numerous efforts have been dedicated to the development of novel and efficient catalyst systems, given the high demand for aldehydes. By immobilizing complexes on the surface of heteroatom-containing porous organic polymers have garnered renewed attention. In this paper, a series of porous organic polymer-supported rhodium catalysts were prepared, of which the results demonstrated that the Rh/PTBA-TTA catalyst with abundant nitrogen and phosphorus exhibited excellent activity (100% conversion) and high linear aldehyde selectivity (74%) for the heterogeneous catalytic hydroformylation reaction of 1-octene. The investigations of catalyst dosage, reaction temperature and partial pressure ratio were conducted. In addition, Rh/PTBA-TTA catalyst displayed broad substrate scope and recyclability. The structures of the catalysts were thoroughly characterized by mean of a spectrum of characterization techniques including FT-IR, XPS, solid-state MAS NMR, SEM and TEM. The data indicate that the presence of highly dispersed Rh active species might be on the Rh/PTBA-TTA catalyst. Moreover, the hot filtration test further confirmed the heterogeneity of the reaction, exhibiting great potential for the industrial applications.
