“…Densities and speeds of sound of both pure liquids and of the mixtures were measured by means of a vibrating-tube densimeter and sound analyzer, Anton Paar model DSA-5000, automatically thermostated within 0.01 K. A detailed description of the calibration of the apparatus has been given in an earlier work . The repeatability of the ρ measurements is 5·10 –3 kg·m –3 , while the relative standard uncertainty of the measurements is estimated to be 0.12%.…”

Values of density (ρ), speed of sound (c) and refractive index (n D) for N,N-dimethylformamide (DMF) + N-propylpropan-1-amine (DPA) or + butan-1-amine (BA) mixtures at (293.15−303.15) K, and for DMF + N-butylbutan-1-amine (DBA) or hexan-1-amine (HxA) mixtures at 298.15 K are reported. Density and speed of sound measurements were conducted using a vibrating-tube densimeter and sound analyser, Anton Paar model DSA5000; refractive index values, n D values were obtained by means of a RFM970 refractometer from Bellingham+Stanley. The experimental ρ, c and n D values have been used to determine excess molar volumes, V m E, excess adiabatic compressibilities, κS E, excess speeds of sound, c E, excess thermal expansion coefficients, α p E, and excess refractive indices, n D E. This set of data shows the existence of interactions between unlike molecules and of structural effects in the mixtures under study. V m E values of solutions including linear secondary amines are lower than those of mixtures with linear primary amines. In fact, the contribution to V m E from the breaking of amine−amine interactions is larger for the latter systems. Calculations on Rao’s constant point out that there is no complex formation between the mixture components. Dispersive interactions have been analyzed by means of the molar refraction. It is shown that solutions with DPA or HxA are characterized by similar dispersive interactions and that they mainly differ by dipolar interactions.
