Volumetric and ultrasonic behaviour of binary mixtures of 1-nonanol with o-cresol, m-cresol, p-cresol and anisole at T = (293.15 and 313.15) K

Densities, rho, and speeds of sound, u, of binary liquid mixtures of 1-nonanol with o-cresol, m-cresol, p-cresol and anisole have been measured over the entire range of composition at T = (293.15 and 313.15) K and at atmospheric pressure. Using these data, the excess molar volume, V-E, molar free volume, V-f, parameters related to space-filling ability. V-f/V, non-linearity parameters. B/A, isentropic compressibility, kappa(S), molar isentropic compressibility, K-S,K-m, deviation of molar isentropic compressibility, K-S,K-m,(E) deviations of the speed of sound, u(D), and limiting excess partial molar volume, (V) over bar (m,j),(E,0) and isentropic compressibility, (K) over bar (m,j),(E,0) have been calculated. The calculated excess and deviation functions have been fitted to the Redlich-Kister polynomial equations and the results analyzed in terms of molecular interactions and structural effects.
