Densities and volumetric properties of (N-acetylmorpholine + aromatic hydrocarbon) binary mixtures from T = (293.15 to 343.15) K

The experimental densities, ρ for binary mixtures of (N-acetylmorpholine + benzene, +toluene, +ethylbenzene, and +mesitylene) have been measured at temperatures from (293.15 to 343.15) K and atmospheric pressure over the whole mole fraction range. From these results, excess molar volumes VE have been calculated and fitted to the Redlich–Kister polynomial equation. The VE values are negative over the whole mole fraction range and at all temperatures. Thermal expansion coefficients αi, apparent molar volumes Vφi, and partial molar volumes at infinite dilution Vi∞ have been calculated. The variation of these properties with composition and temperature of the binary mixtures are discussed in terms of molecular interactions.
