Abstract
        The kinetics of the esterification of oleic and linoleic acids using a batch reactor are described                                     in this study. Effect of relevant factors on ester conversion, such as reaction temperature, dose of sulphuric acid as a catalyst, and methanol/FFAs (oleic and linoleic acid) mole ratios are studied. The results showed that the maximum conversion of oleic and linoleic were 88% at 40:1 methanol/FFA molar ratio at 68°C, catalyst 2 wt. % of FFA and reaction time 30 min. A pseudo-homogeneous kinetic model was proposed for the esterification. The influence of Temperature on the rate constants is presented by Arrhenius equation, and the activation energies were found to be 43.42 and 45.51 kJ/mol for linoleic and oleic acid, respectively.
