Abstract
Oalculations of activity coefficients for thirty isobaric binary systems from vapor-liquid equilibria data were made using the Gilmont equation© An extensive literature survey showed the Gilmont equation provides an excellent means of correlating equilibrium data in most binary isothermal systems° However, the Gilmont equation’s applicability to isobaric systems had not been satisfactorily proven, and became the object of this investigation.
The Gilmont equation gave satisfactory correlation of the binary isobaric data for various systems. The correlation was found to improve as the systems approached ideal behavior. The introduction of a temperature correction to the relative volatility, term improved the correlation then the original fit was poor. However, comparison of the Gilmont equation to the Van Laar and Margules equations, on the same binary systems, showed little advantage for the Gilmont equation. In addition, calculations by the Gilmont equation were found to be lengthy. Obtaining the necessary equation constants was difficult because of the sensitivity of the difference equations to small data inconsistencies. Therefore, the use of the Gilmont equation is not recommended for binary isobaric systems unless the two constant Van Laar and Margules equations give unsatisfactory correlation.
