Abstract

On the basis of eliminating the influence of external diffusion, the reaction kinetics data were measured under the conditions of stirring speed of 700 r/min, reaction temperature of 348.15-368.15 K and catalyst dosage of 10%-15% (based upon the total mass of cyclohexyl acetate and water) and the hydrolysis kinetics of cyclohexyl acetate for the preparation of cyclohexanol over the ion-exchange-resin catalyst (D006) was studied. The Langmuir-Hinshelwood-Hougen-Watson (LHHW) kinetic model based upon the activity was established and the model parameters were fitted by non-linear least-square method. The results showed that the pre-exponential factor, the activation energy and the standard reaction enthalpy of the hydrolysis reaction were 9.532×106 mol/(g·min), 60.94 kJ/mol and 21.85 kJ/mol respectively. The kinetic model fitted well with the experimental data.
