ABSTRACT

The densities, ?, 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, were calculated. The values were negative over the whole composition range for all the mixtures and at each temperature studied, except for BA + mesitylene which exhibit positive values, indicating the presence of specific interactions between BA and aromatic hydrocarbon molecules. The deviations in values follow the order: benzeneless thantolueneless thanp-xyleneless thanm-xyleneless thano-xyleneless thanmesitylene. It is observed that values depend upon the number and position of the methyl groups in these aromatic hydrocarbons.
