Benzyl acetate was synthesized by the reaction of benzyl chloride with sodium acetate in a two-phase system of an aqueous solution and toluene using tricaprylylmethylammonium chloride (QCl) as a phase-transfer catalyst. The distribution coefficient and chemical equilibrium constants of QCl and tricaprylylmethylammonium acetate were used to analyze the kinetics of the esterification. Two models were used to obtain the reaction rate constant and to simulate the kinetics, i.e., (i) simple ion exchange across the interface, and (ii) anion exchange in the aqueous phase. The overall reaction can be described by a first-order reaction with respect to the molar concentration of benzyl chloride and the active intermediate produced by the reaction between QCl and acetate ion in the organic phase, respectively.
