dc.description.abstractInterfacial tensions were determined for the five ternary systems water-isopropyl alcohol-benzene, water-isopropyl alcohol-toluene, water-tertiary butyl alcohbl-benzene, water-normal propyl alcohol-toluene, and water-dlethylamlne-toluene in their regions of two liquid phases. Also determined were surface tensions, densities, and refractive indices of the phases. A Fisher Surface Tensiometer employing the ring method was used to make the surface and interfacial tension determinations. A Fisher- Davidson Gravltometer was used to make the density measurements and refractive indices were determined by means of a Bausch and Lomb Abbe-3L Refractometer. A comparison was made of the values determined for the binary and pure liquid phases of the above ternary systems with the accepted values found in the literature. A maximum deviation of 2.81 was indicated. As the other measurements were made under the same conditions all values determined were considered to be in error by no more than 2.8%. A relative immiscibility scale was established for each system by means of the differences of the refractive indices of the conjugate phases. Interfacial tensions of each of the systems were correlated against the corresponding immicibilities established for the phases. A straight line function was indicated for plots of the immiscibility values against the log of the log of one hundred times the interfacial tensions. Correlation coefficients determined for the curves showed a 951 certainty of this type of correlation for one of the systems, a 981 certainty for another, and 991 certainties for the remaining three systems.
