Abstract
Excess volume (VE123) and speed of sound (u123) data for three ternary mixtures were reported at 303.15K. The mixtures include 1,1,1-trichloroethane and acetophenone as common components. The non-common components were chosen as 1-alkanols namely 1-propanol, 1-butanol and 1-pentanol. The experimental speed of sound and density data of ternary mixtures were used to compute isentropic compressibility (κs123) and the quantity Δκs123, the difference between measured value and that computed from the constituent binary data. Further, experimental ternary excess volume data were compared with predictive expressions in terms of Redlich–Kister, Kohler and Tsao–Smith equations. The experimental data were analyzed on the basis of intermolecular interactions between component molecules and also in terms of constituent binary data.
