Speed of sound and isentropic compressibility of the ternary mixture (2-butanol plus n-hexane plus 1-butylamine) and the constituent binary mixtures at 298.15 K and 313.15 K

Densities and speeds of sound for ( 2-Butanol + n-Hexane + l-Butylamine) at 298.15K and 313.15 K, acid the constituent binary mixtures (2-Butanol + n- Hexane), (2-Butanol + l-Butylamine) at 298.15 K and 313.15 K, and (n-Hexane + I-Butylamine), at 313.15 K have been measured. The isentropic compressib ilities, the excess isentropic compressibilities, and the speeds of sound d eviations have been calculated for both the binary and the ternary systems, from the experimental data. The isentropic compressibilities have been com pared with calculated values from the Free Length Theory (FLT) and Collisio n Factor Theory (CFT). (C) 2000 Elsevier Science B.V. All rights reserved.
