Abstract: The excess volumes of ten binary systems namely benzene +2-butanone, +acetonitrile, +acrylonitrile, +ethyl acetate, +methyl acrylate; toluene +2-butanone, +acetonitrile, +acrylonitrile, +ethyl acetate, +methyl acrylate have been measured over entire composition range at 293.15 K. The results indicate that the excess volumes for systems containing nitriles or ketone are negative, a double bond in the nitrile causes a significant decrease in V~E. Inversely, the excess volumes for systems containing esters are positive or slight negative, a double bond in it causes a significant increase in V~E. It may be conclude that the dipole interaction is not the only cause of the deviation, and there are a specific interaction between aromatic and nitrile or ketone molecules, while the unlike interaction between aromatic and ester belongs to van der Waals type.
