Isentropic Compressibility and Volumetric Properties of [Difurylmethane plus (Acetonitrile or Propionitrile or Benzonitrile)] Binary Mixtures at 298.15 K

Densities (rho) and speed sound (u) of binary systems of difurylmethane (DFM) with acetonitirile (ACN), benzonitrile (BCN) or propionitrile (PCN) have been measured over the entire composition range at 298.15 K and atmospheric pressure. Excess isentropic compressibilities (K-s(E)), and excess ultrasonic speeds, u(E), of [DFM + (ACN or BCN or PCN)] and excess molar volumes (V-m(E)), of [DFM + (BCN or PCN)] binary systems were determined and correlated by the Redlich-Kister equation. The results have been discussed in terms of possible intermolecular interactions and structural effects.
