GASPHASEN HYDROFORMYLIERUNG VON 1-HEXEN MIT SUPPORTED LIQUID PHASE CATALYST (SLPC) RhHCO(PPh3)3

Article abstract of DOI:10.1016/S0022-328X(00)88378-3

Hydroformylation of 1-hexene in the gas phase has been carried out at 120 deg C and 3 to 9 bar pressure with solution of the homogeneous catalyst RhHCO(PPh3)3 in molten PPh3, which was dispersed into the pores of the carrier Chromosorb.Above a critical gas flow no condensation of product heptanal (b.p. 155 deg C) was observed.Conversion of 1-hexene to heptanal is a function of reactor length, gas flow and pressure of CO/H2.The ratio of n/iso-aldehyde can be adjusted to 45/1 and is much higher than in liquid bulk hydroformylation.
