Behavior of <i>n</i>-hexene-1 in hydroformylation of olefin mixtures over rhodium supported porous metal-organic framework MOF-5

Metal organic framework MOF-5 was synthesized and used for the preparation of rhodium supported catalyst. Acetylacetonato(1,5-cyclooctadiene)rhodium(I) was used as catalyst precursor. The material was characterized by XRD, FTIR, TEM, AAS, and nitrogen adsorption. The catalytic properties of Rh@MOF-5 were investigated in the hydroformylation of olefins and olefin mixtures with different chain length to the corresponding aldehydes. High conversion and selectivity to n-aldehydes were achieved. Interestingly, shorter chain length molecule, n-hexene-1, shows different behavior in the hydroformylation of its mixtures, n-aldehyde is more favor in short reaction times. The obtained results indicate that rhodium active sites are highly dispersed inside the pores of the MOF-5 framework.
