Densities and Volumetric Properties of Binary Mixtures of Butyl Acrylate with Benzene, Toluene, o-Xylene, m-Xylene, p-Xylene, and Mesitylene at Temperatures from 288.15 K to 318.15 K

Abstract

The densities, ρ, of binary mixtures of butyl acrylate (BA) with benzene, toluene, o-xylene, m-xylene, p-xylene, and mesitylene, including those of pure liquids, over the entire composition range were measured at the temperatures (288.15, 293.15, 298.15, 303.15, 308.15, 313.15, and 318.15) K and atmospheric pressure. From the experimental data, the excess molar volumes, ${V_{\rm m}^{\rm E}}$ were calculated. The ${V_{\rm m}^{\rm E}}$ values were negative over the whole composition range for all the mixtures and at each temperature studied, except for BA + mesitylene which exhibit positive ${V_{\rm m}^{\rm E}}$ values, indicating the presence of specific interactions between BA and aromatic hydrocarbon molecules. The deviations in ${V_{\rm m}^{\rm E}}$ values follow the order: benzene<toluene<p-xylene<m-xylene<o-xylene<mesitylene. It is observed that ${V_{\rm m}^{\rm E}}$ values depend upon the number and position of the methyl groups in these aromatic hydrocarbons.
