    Abstract
    Densities (ρ) of pure difuryl methane (DFM), N-methylformamide (NMF), N-ethylformamide (NEF), N,N-dimethylformamide (DMF) and N,N-dimethylacetamide (DMA) and those of [DFM + (NMF or NEF or DMF or DMA] binary mixtures over the entire composition range, have been measured at (T = 293.15, 298.15 and 303.15) K and atmospheric pressure. Excess molar volumes (), of each binary system were calculated and correlated by the Redlich-Kister equation. values for each binary system were negative at each of the three temperatures investigated (T = 293.15, 298.15 and 303.15) K. The values decreased with temperature increase for each of the binary systems investigated. Sign and magnitude of are discussed in-terms of type and nature of intermolecular interactions that occur in a binary mixture. The data have been used to derive excess partial molar volumes (), limiting excess partial molar volumes () and limiting partial molar volumes at infinite dilute region () of each component of the binary mixture. Results are discussed in terms of possible intermolecular interactions and structural effects that occur in the binary mixtures.
