چکیده	This paper represents a methodology for kinetic parameter estimation based on standard optimization methods. The parameter estimation procedure is applied to the example o f modelling of non-catalytic transesterification reaction, based on laboratory experiments performed under elevated pressure. The kinetic model employed in this study consists o f three consecutive and parallel reversible reactions of the second order, with six kinetic constants. The influence of the mass transfer effects was considered as well. The best results were obtained by Genetic Algorithm method. The application of this method resulted in kinetic parameters with improved accuracy in predicting concentrations o f important reaction intermediates, i.e., diglycerides and monoglycerides. Activation energies of kinetic parameters obtained by the Genetic Algorithm method are in line with theoretical values determined by molecular orbital calculations.
