Influence of Support Structure on Catalytic Performance of Supported Liquid-Phase (SLP) Catalysts in Hydroformylation of 1-Butene

Abstract Several supported liquid-phase (SLP) catalysts with immobilized Rh-biphephos complexes on monolithic supports were prepared and applied for continuous gas-phase hydroformylation (HyFo) of 1-butene. The support comprised macroporous silicon carbide (SiC) deposited silica nanoparticles (NPs) in order to provide mesopores enhanced capillary forces retain the liquid-phase. Variable parameters examined SiC supports, including size loading NPs intermediate calcination between deposition steps obtain most efficient configuration SLP system. larger gave higher catalytic activity (i.e. 1-butene conversion turnover frequency) compared smaller sized NPs. However, selectivity towards preferred linear aldehyde was containing less small Importantly, catalyst systems showed long-term stability HyFo negligible formation high boiling aldol condensation products.
