Abstract EN
Speeds of sound and density for binary mixtures of ethyl benzoate (EB) with N,N-dimethylformamide (NNDMF), N,N-dimethyl acetamide (NNDMAc), and N,N-dimethylaniline (NNDMA) were measured as a function of mole fraction at temperatures 303.15, 308.15 K, 313.15 K, and 318.15 K and atmospheric pressure.
From the experimental data, adiabatic compressibility (βad), intermolecular free length (Lf), and molar volume (V) have been computed.
The excess values of the above parameters were also evaluated and discussed in light of molecular interactions.
Deviation in adiabatic compressibilities and excess intermolecular free length (LfE) are found to be negative over the molefraction of ethyl benzoate indicating the presence of strong interactions between the molecules.
The negative excess molar volume VE values are attributed to strong dipole-dipole interactions between unlike molecules in the mixtures.
The binary data of Δβad, VE, and LfE were correlated as a function of molefraction by using the Redlich-Kister equation.
