The kinetics of gas-phase propene hydroformylation over a supported ionic liquid-phase (SILP) rhodium catalyst

► Kinetic orders with respect to H2 and CO are dependent upon reaction temperature. ► Reaction temperature is a tunable parameter to control the regioselectivity. ► The rate-determining step is alkene insertion and oxidative addition of H2 at low and high temperature, respectively. ► Derived rate expressions are consistent with kinetic studies and can be used to adequately model the experimental data.
