| Abstract: | The kinetics of the esterification reaction between acetic acid and epichlorohydrin catalysed by Purolite A-520E strong basic
anion exchange resin was studied. The effects of certain parameters such as stirring speed, particle diameter, temperature,
catalyst amount and molar ratio between reactants were experimentally determined. It was found that the overall reaction rate
is intrinsically kinetically controlled. The partial orders of reaction with respect to catalyst, acetic acid and epichlorohydrin
were determined. A reaction mechanism is proposed. Based on chromatographic data and taking into account the partial orders
of reaction, a more detailed kinetic model is suggested.
