Isothermal vapor-liquid equilibrium (VLE) data were measured for mixtures of methyl benzoate with four normal alkanes (from butane to heptane) at temperatures from (353.15 to 453.15) K using an in situ infrared absorption method already validated in previous work. With this method, a mathematical treatment of the absorption spectra allows the determination of the molar density of each species in the liquid phase. Mole fractions and bubble curves are then determined. The newly measured data are compared to calculations made using a purely predictive approach with the polar GC-SAFT equation of state. The agreement with the experimental data is satisfactory (< 10 %) since the data were not used to determine the parameters of the model.
