Ultrasonic velocity (U), density (rho) and viscosity (eta) for the ternary liquid mixtures of diisopropyl ether+2,2,2-trifluoroethanol+1-propanol, diisopropyl ether+2,2,2-trifluoroethanol+1-butanol and diisopropyl ether+2,2,2-trifluoroethanol+1-pentanol have been measured as a function of the composition at 303, 308 and 313 K. The experimental data have been used to calculate some excess thermodynamical parameters such as viscosity (eta(E)), adiabatic compressibility (beta(E)), free length (L(f)(E)), free volume (V(f)(E)), internal pressure (pi(E)(i)) and Gibb's free energy (Delta G(E)). The results have been discussed and interpreted in terms of structural and specific interaction predominated by hydrogen bonding.
