Studies of Viscosities and Excess Molar Volumes of the Binary Mixtures of 1-Heptanol + 1,2-Dichloroethane,+ 1,1,1-Trichloroethane,+ 1,1,2,2-Tetrachloroethane,+ Trichloroethylene and Tetrachloroethylene at (293.15,298.15,and 303.15) K for the Liquid R

摘要

Densities (rho) and viscosities (eta) 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) Kfor the liquid region and at ambient pressure for the whole composition range.Excess molar volumes (V~E),excess thermal expansivities (alpha~E),and viscosity deviations (deltaeta) 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.
