ABSTRACT

In this work, densities of binary mixtures of {water + formamide (FM), or + N,N-dimethylformamide (DMF), or + dimethylsulfoxide (DMSO), or + N,N-dimethylacetamide (DMA), or + 1,4-dioxane}, 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 V E m values have been fitted to Redlich Kister polynomial equation and others volumetric properties were calculated. The partial molar volumes at infinite dilution of each component o?V 1i P have been determined using three different methods.
