This paper reports on the kinetics of the synthesis of benzyl acetate, benzyl benzoate, and benzyl n-butyl phthalate as studied using tertiary amines as the phase-transfer catalyst. The sodium salt of the organic acid is dissolved in water as the aqueous phase. Sodium bromide or sodium iodide is added to the aqueous phase as the cocatalytic agent. Tributylamine with a suitable amount of sodium iodide is an effective phase-transfer catalyst. The overall reaction can be described by a first-order reaction with respect to the molar concentration of benzyl chloride in the organic phase. The activation energies are not very different as compared with those using quaternary ammonium salts as the phase-transfer catalyst.
