Cilj diplomskega dela je bil razviti kinetični model in mehanizem monoesterifikacije, tipične reverzibilne reakcije. Kot primer smo uporabili monoesterifikacijo etilen glikola z benzojsko kislino. Reakcija je bila katalizirana v kislem mediju ob prisotnosti α-aluminijevega oksida. Vsi eksperimenti so bili izvedeni v avtomatiziranem reakcijskem kalorimetru, opremljenim z in-line IR spektrometrom. Na osnovi IR spektrov in metodologije umeritvene krivulje smo dobili koncentracijske profile produkta. Določili smo red reakcije, obe konstanti proizvodnosti in aktivacijsko energijo. Z uporabo kinetičnih in stehiometričnih podatkov smo ugotovili reakcijski mehanizem, ki pojasnjuje opažene značilnosti reakcije.The goal of this work was to develop the kinetic model and mechanism of monoesterification, a typical reversible reaction. As an example we used the ethylene glycol monoesterification with benzoic acid. The reaction was catalyzed in acidic medium supported with α-aluminum oxide. All experiments were carried out in an automated reaction calorimeter equipped with an in-line IR spectrometer. Based on the observed IR spectra and calibration curve methodology, product concentration profiles were obtained. Reaction order together with both reaction rate constants and activation energy have been determined. Using the obtained kinetic and stoichiometric data, the reaction mechanism was established which explains the observed reaction characteristics
