The effect of various parameters such as liquid circulation flow rate, temperature, catalyst loading, and mass ratio of the reactants was studied in detail. The equilibrium constants of the direct hydration were calculated on the basis of the activities that were predicted using UNIFAC group contribution method. A pseudohomogeneous (PH) model was used to correlate the kinetic data in the temperature range from 353.15 to 383.15 K. The estimated kinetic parameters make the calculated results in excellent agreement with the experimental results, indicating that the PH model gives a good representation of the kinetic behavior for the direct hydration of DHM.
