| Abstract: | The selective oxidation of o-chlorotoluene(OCT)to the important chemical intermediate o-chlorobenzaldehyde(OCBD)by molecular oxygen under the catalytic system of Co(OAc)2·4H2O/Mn(OAc)2·4H2O/KBr in a microchannel reactor is a green and safe process.In order to understand the nature of the process deeply and lay the foundation for process scale-up,the kinetics of the selective oxidation was studied.A lumped kinetic scheme and kinetic model for the selective oxidation of OCT were proposed.By eliminating the influence of mass transfer and oxygen,a series of kinetics data were obtained under the condition of kinetics control,and the experimental data were nonlinear fitted by Matlab software.The results showed that the calculated values on the model were consistent with the experimental data. |
