ABSTRACT

Densities (F) and viscosities (e) of the binary mixtures of 1-heptanol with 1,2-dichloroethane, 1,1,1- trichloroethane, 1,1,2,2-tetrachloroethane, trichloroethylene, and tetrachloroethylene have been measured at (293.15, 298.15, and 303.15) K for the liquid region and at ambient pressure for the whole composition range. Excess molar volumes (V E), excess thermal expansivities (RE), and viscosity deviations (ae) were calculated and correlated by Redlich-Kister type function to determine the fitting parameters and the standard deviations. The results are consistent with the self-association of 1-heptanol and the polar and nonpolar characters of used chloroethanes or chloroethylenes, which produce the dissociation of 1-heptanol. The two-parameter Heric interaction model has also been used to correlate the kinematic viscosities of binary liquid mixtures with mole fractions.
