Hydroformylation of 1-Octene Using BmimPF6−Decane Biphasic Media and Rhodium Complex Catalyst: Thermodynamic Properties and Kinetic Study

摘要

A chemical reaction engineering approach is reported to investigate the biphasic hydroformylation of 1-octene using [bmim][PF6] ionic liquid. It is based both on a process parameter investigation (temperature, concentrations, and pressures) and a thermodynamic study of the reaction medium (gas−liquid and liquid−liquid equilibria). Initial rate data show complex behavior with respect to operating parameters and are best described by a rate equation based on a mechanistic model. Complete reaction scheme including isomerization is then modeled accounting from the time dependent concentration of the organic substrates measured in organic phase and recalculated in ionic liquid phase from liquid−liquid equilibria.
