Abstract
Ultrasonic velocities of the ternary system Benzene(1) + Acetone(2) + Chloroform(3) and the corresponding binary mixtures {Benzene(1) + Acetone(2)}, {Benzene(1) + Chloroform(2)} and {Acetone(1) + Chloroform(2)} have been measured over the entire composition range at atmospheric pressure and at 298.15 K. All the isentropic compressibilities, ultrasonic velocity deviations and deviations in isentropic compressibilities for both the binary and ternary mixtures were calculated from experimental data. Ultrasonic velocity and isentropic compressibilities have been compared with calculated values from Free Length Theory (FLT), Collision Factor Theory (CFT), Nomoto's relation (NR), Junjie's relation (JR) and Van Deal's Ideal Mixing relation (IMR). Ultrasonic velocity deviations, Δu, deviations in isentropic compressibilities, σK s, have been fitted to the Redlich-Kister equation in the case of binary mixtures, while the equation of Cibulka was used to fit the values related to the ternary system.
