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 g lycerol trioleate + chloroform, at 10, 15, 20, 25,and 30 degrees C, an d 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 t hrough empirical relations. The standard deviations from the derived v iscosity equation were of the same order of magnitude as the experimen tal uncertainties. The excess volumes (V-E) have been derived from the density measurements. V-E values were positive for the glycerol triol eate + chloroform system and negative for the other mixtures over the entire range of mole fractions covered in this study. The departure fr om the ideal behavior is explained on the basis of specific interactio ns between the components in these mixtures.
