The kinetic studies of hydroformylation of 1-butene to produce pentanal were investigated by using Rh/PPh₃ complex as homogeneous catalyst, valeraldehyde and its polycondensates as solvent. The experiment was carried out on small hydroformylation continuous reaction installation. The effects of reaction temperature, the concentration of 1-butene, the partial pressure of CO or H₂ and the concentration of rhodium of catalyst on the reaction rate were studied. Based on the reaction mechanism of hydroformylation and the latest research results of hydroformylation kinetics, the kinetic equation suitable for the hydroformylation of 1-butene was established. The parameters of the kinetic equation were regressed and verified with the experimental data. The relationship between the normal/isomeric ratio of pentanal and the partial pressure of CO was further explored.
