Viscosities and Densities of Dilute-Solutions of Glycerol Trioleate Plus Octane, Plus P-Xylene, Plus Toluene, and Plus Chloroform
Dynamic viscosities (eta) and densities (rho) of dilute solutions of glycerol trioleate + chloroform, at 10, 15, 20, 25,and 30 degrees C, and of glycerol trioleate + octane, + p-xylene, + toluene, at 20, 25, 30, 35, and 40 degrees C, were measured. The dynamic viscosities and the excess volumes were correlated with the composition and temperature through empirical relations. The standard deviations from the derived viscosity equation were of the same order of magnitude as the experimental uncertainties. The excess volumes (V-E) have been derived from the density measurements. V-E values were positive for the glycerol trioleate + chloroform system and negative for the other mixtures over the entire range of mole fractions covered in this study. The departure from the ideal behavior is explained on the basis of specific interactions between the components in these mixtures.
