Speed of sound and isentropic compressibility of (1-butanol plus n-hexane plus 1-chlorobutane) and the constituent binary mixtures at the temperatures 298.15 K and 313.15 K

Densities rho and speeds of sound u for {x(1)C(4)H(10)O + x(2)C(6)H(14) + ( 1 - x(1) - x(2))C4H9Cl} at T = 298.15 K and T = 313.15 K, and the constitue nt binary mixtures {xC(6)H(14) + (1 - x)C4H9Cl} at T = 298.15 K and {xC(4)H (10)O + (1 - x)C6H14}, {xC(4)H(10)O + (1 - x)C4H9Cl}, and {xC(6)H(14) + (1 - x)C4H9Cl} at T = 313.15 K have been measured. The isentropic compressibil ities kappa(S) the excess isentropic compressibilities kappa(S)(E), and the speeds of sound deviations Delta u have been calculated for both the binar y and the ternary systems, from the experimental data. The isentropic compr essibilities have been compared with calculated values from the free length theory (FLT) and collision factor theory (CFT). (C) 2000 Academic Press.
