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, ρ, 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, VE, molar free volume, Vf, parameters related to space-filling ability, Vf/V, non-linearity parameters, B/A, isentropic compressibility, κS, molar isentropic compressibility, KS,m  , deviation of molar isentropic compressibility, KS,mE, deviations of the speed of sound, uD  , and limiting excess partial molar volume, V¯m,iE,0, and isentropic compressibility, K¯m,iE,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.
