摘要：

The kinetics of hydroformylation of vinyl acetate using [Rh(CO)2Cl]2 complex catalyst has been investigated at 80-degrees-C. The trends are quite different from those observed for the HRh(CO)(PPh3)3-catalyzed systems. The dependence of the rate on P(H2) and P(CO) was found to be linear, whereas the dependence of rate on vinyl acetate concentration was found to be first order, followed by substrate-inhibited kinetics at higher olefin concentrations. The rate dependence on the catalyst concentration was found to be fractional order. A rate equation has been proposed and kinetic parameters evaluated.
