Volumetric Properties of (Difurylmethane + Alkan-1-ol) Binary Mixtures at 298.15 K

摘要

Densities (ρ)of the binary systems of {difurylmethane + (ethanol or propan-1-ol or butan-1-ol or pentan-1-ol or hexan-1-ol)} have been measured with an Anton Paar DMA 4500 vibrating-tube densimeter over the entire composition range at 298.15,K and atmospheric pressure. Excess molar volumes (V m E ) of each binary system were determined and correlated by the Redlich-Kister equation. Limiting (V i E,∞) and excess partial molar volumes (V i E ) of components of each binary system have been calculated to provide insight into the intermolecular interactions present and the packing efficiencies. The results have been discussed in terms of specific intermolecular interactions, dispersive forces and structural effects.
