The experimental values of densities [rho], excess volumes [V.sup.E], viscosities [eta], speeds of sound u, and isentropic compressibility [k.sub.s] of the binary mixtures of methyl benzoate with tetrahydrofuran, 1,4-dioxane, anisole, and butyl vinyl ether at temperatures 303.15, 308.15, and 313.15 K are listed in Table 2.
The variations of excess volume [V.sup.E] with mole fraction [x.sub.1] of methyl benzoate at the studied temperatures for the binary mixtures are displayed in Figure 1.
The dielectric constants of methyl benzoate, tetrahydrofuran, 1,4-dioxane, anisole, and butyl vinyl ether are [member of] = 6.02, 7.261, 2.209, 4.33, 3.9, respectively.
The dependence of [DELTA][G.sup.*E] on themole fraction is shown in Figure 3, where itwas observed that [DELTA][G.sup.*E] is positive for mixtures of methyl benzoate with tetrahydrofuran, 1,4-dioxane, and anisole, whereas for mixtures of methyl benzoate + butyl vinyl ether, the values of [DELTA][G.sup.*E] are negative over the entire range of composition.
The plots of [DELTA][k.sub.s], as displayed in Figure 4, show that for methyl benzoate with tetrahydrofuran, 1,4-dioxane, and butyl vinyl ether, the values of [DELTA][k.sub.s] exhibit negative deviation over the entire range of mixture composition; while for methyl benzoate + anisole, the values of [DELTA][k.sub.s] exhibit positive deviations.
The densities [rho], excess volumes [V.sup.E], viscosities [eta], speeds of sound u, and data of binary mixtures methyl benzoate with tetrahydrofuran, 1,4-dioxane, anisole, and butyl vinyl ether have been reported at (303.15, 308.15 and 313.15) K.
