Kinetic Study of Transesterification of Methyl Acetate with Isobutanol Catalyzed by the Dissociation of Sodium Hydrogen sulphate in Alcoholic Media

Abstract

The reaction kinetics of the liquid-phase transesterification of methyl acetate and isobutanol is investigated. The reaction has been catalyzed by sulphuric acid generated by the dissociation of sodium hydrogensulfate in alcoholic media. The experiments are carried out in a stirred batch reactor at different temperatures (50, 70 and 90 °C), determining its influence. The experimental results have been modelled assuming a homogeneous model based on the Arrhenius expression. The model fits satisfactorily the experimental data that can be seen from the statistics and errors calculation. A kinetic equation which describes the reaction catalyzed by sodium hydrogen sulfate is provided.
