| Abstract: | The densities, ultrasonic velocities and
refractive indices of binary mixtures of propylene carbonate + ethanol, n-propanol and n-butanol at 298.15, 303.15 and 308.15 K have been measured over
the whole mole fraction range. Experimental data have been used to estimate the
isentropic compressibility (Ks),
intermolecular free length (Lf),
specific acoustic impedance (Z),
polarizability ( ) and their deviations excess isentropic compressibility (KsE), excess
intermolecular free length (LfE),
excess acoustic impedance (ZE)
and excess refractive index ( nD). The results have been fitted to Redlich-Kister equation and
discussed in terms of molecular interactions. |
