Refractive index, nD, and density, , have been measured at 298.15 K and atmospheric pressure, for the binary mixtures of toluene with methyl acetate, methyl propanoate, methyl butanoate, methyl heptanoate, or butyl acetate. From these experimental data refractive index deviations, nD, molar refraction, R, molar refraction deviation, R, and excess molar volume, VE were calculated. Refractive indices were compared with those predicted using several mixing rules.
