Intercalation of HRh(CO)(TPPTS)3 complex into the interlayer space of hydrotalcite was carried out to prepare an eco-friendly heterogeneous hydroformylation catalyst. Intercalated catalyst was characterized by 31P NMR, P-XRD, FT-IR, SEM and surface area measurements. Catalytic activity of intercalated catalyst [HT(3.5)-INT] was evaluated for hydroformylation of linear alkenes of varied carbon number from C5 to C13 as well as cyclic alkenes. Selectivity of the aldehydes was observed to decrease with increase in the carbon chain length of linear alkenes. Effect of reaction parameters on catalytic activity of intercalated catalyst was studied by varying the catalyst amount, 1-hexene concentration, reaction temperature, partial pressure of carbon monoxide and hydrogen for hydroformylation of 1-hexene. The catalyst was re-cycled up to five times without significant loss in the alkene conversion and selectivity of aldehydes.
Graphical abstractThe intercalation of HRh(CO)(TPPTS)3 complex into interlayer space of hydrotalcite was carried out to prepared an eco-friendly heterogeneous catalyst for hydroformylation of alkenes. The catalyst showed excellent activity for hydroformylation of linear alkenes of varied carbon number from C5 to C13 as well as cyclic alkenes.Figure optionsDownload full-size imageDownload as PowerPoint slide
