| Abstract: | Ultrasonic
velocity (U), density (ρ) and
viscosity ( ) 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-trifluoro-ethanol+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 (E), adiabatic compressibility ( E), free length (LEf), free
volume (VEf), internal pressure ( Ei) and Gibb’s free energy ( GE). The results have been
discussed and interpreted in terms of structural and specific interaction
predominated by hydrogen bonding. |
