Abstract
The Margules equation as modified by Wohl for ternary liquid-vapor systems, is used to develop ternary activity coefficients at different concentrations and varying temperatures. Corresponding binary experimental data are necessary to mathematically obtain these ternary activity coefficients. A trial and error graphical technique is used to examine the ternary data for azeotropic conditions. Convergence on ternary graph paper can be easily detected after the first two trials. Divergence is an indication that the system under consideration is nonazeotropic.
Most of the azeotropic systems investigated agreed quite well with published data. The range of disagreement of concentrations for component a in the system was between 0.8 and 6.0 weight percent. This method proved to be more accurate than the Horvath technique. 5
This analytic procedure is a useful technique to accurately predict the existence or nonexistence of azeotropes in various ternary systems. It is independent of the criterion that binary azeotropic pairs exist among the three components.
