To verify the accuracy of the determined kinetic parameters the simulated temporal concentration courses of the reaction are compared with experimental data. In Fig. 7 the experimentally determined temporal course of the mass fraction of ethyl oleat for the reaction temperatures of 348.15 K and 378.15 K are compared with the simulated results. It can be shown that the experimental data well agree with the applied activity- based kinetic approach of second order. The simulated molar fractions of all components in comparison to the experimental values for the kinetic experiments between 348.15 K and 393.15 K can be found in Fig. 8.
