Densities, Refractive Indices, and Excess Properties of Binary Mixtures of 1,4-Dioxane with Benzene, Toluene, o-Xylene, m-Xylene, p-Xylene, and Mesitylene at Temperatures from (288.15 to 318.15) K

Abstract: The densities (ρ) and refractive indices (n) of binary mixtures of 1,4-dioxane with benzene, toluene, o-xylene, m-xylene, p-xylene, and mesitylene, including those of pure liquids, over the entire composition range expressed by mole fraction x 1 of 1,4-dioxane were measured at temperatures (288.15, 293.15, 298.15, 303.15, 308.15, 313.15, and 318.15) K under atmospheric pressure. From the experimental data, the excess molar volumes (V m E), deviations in refractive indices (Δn), partial molar volumes (V m,1 °∞… Show more

“…The increase in values with the increase in number of -CH 3 groups implies that dipole-induced dipole interaction is weaker in higher hydrocarbon owing to its decreased polarizabilities with the increase of -CH 3 groups. A similar type of study was reported by Nain et al [16] for 1,4-dioxane and hydrocarbons. The observed values are in the order of Benzene < Toluene < p-xylene < m-xylene < o-xylene < Mesitylene Addition of two methyl groups in benzene ring in xylenes further exceeds the electron donating capacity, when compared to toluene, but at the same time steric (hindrance) repulsion between methyl groups of 1-iodobutane which hinders proper orientation that is expected to be more.…”

“…The comparison with the literature allowed us to determine a high reproducibility for benzene [28,29,30] and DMSO [31,26,32,33,27] (See Table 2). Additionally, the measurements at 657.7 nm were compared with those values of the literature deterined at the closed wavelength available, e.g.…”
