Viscosities of the ternary mixture (1-butanol+n-hexane+1-chlorobutane) at 298.15 K and 313.15 K

Viscosities of the ternary mixture (1-butanol+n-hexane+1-chlorobutane) and the binary mixture (n-hexane+1-chlorobutane) have been measured at 298.15 K and 313.15 K. Viscosity deviations and excess Gibbs energy of activation of viscous flow for the binary and ternary systems were fitted to Redlich–Kisterʹs and Cibulkaʹs equations. The `viscosity–thermodynamicʹ model (UNIMOD) has been used to correlate experimental data for the binary mixtures and to predict the viscosities for the ternary system. The Group-Contribution Thermodynamic–Viscosity model (GC-UNIMOD), and the group contribution method proposed by Wu have been used to predict the viscosity of the binary and ternary systems.
