ABSTRACT

In this work, densities of binary mixtures of {acetonitrile + di-n-butyl ether (DNBE), or + tetrahydrofuran (THF), or + 1,4-dioxane (DIO), or + di-isopropyl ether (DIPE)}, have been determined under atmospheric pressure as a function of composition and temperature using a vibrating-tube densimeter. The temperatures studied were T = (288.15, 293.15, 298.15, and 303.15) K. The excess molar volumes oV E mP, calculated from density data, are negative over the whole mole fraction range for the temperature range studied. The partial molar volumes at infinite dilution of each component oV1i P have been determined using three different methods. The experimental results have been used to test the applicability of the Prigogine Flory Patterson (PFP) theory
