“…Here again, it is not possible to determine how the activity coefficients in the liquid phase change with temperature from equilibria data alone. Heats of mixing measurements are available by Mathieson and Thynne (1956), Murakami et al (1969), Rastogi et al (1967, and Sturtevant and Lyons (1969), in addition to measurements of the excess volume of mixtures by Nigam and Singh (1969) and Rastogi et al, confirming the existence of weak nonideality in the benzene-toluene mixture.…”

A procedure for the evaluation of low-pressure vapor-liquid equilibria for binary systems is presented that is suitable for tray efficiency evaluation. The method utilizes experimental vapor-liquid equilibria and heats of mixing data, with correlation of activity coefficients in the liquid phase by the Wilson equation. A way is shown to determine the effect of temperature in changing the activity coefficients.

“…9 and 10 show the experimental and calculated values for the system with o-xylene. The experimental HE and V E values were taken from Murakami et al 36 Systems with such small values for the excess properties are not suitable for testing theoretical models since even small absolute discrepancies may lead to differences between the experimental and calculated values ; thus no significant conclusion can be reached about the relative performance of the several models and, as expected, none of them gives satisfactory results for VE and HE.…”

“…The experimental value is 0.03 for the BEN/TOL mixture. 37 The corresponding simu-lated values of ⌬G ij were Ϫ25͑3͒ and +10͑7͒ cm 3 / mol for the two mixtures, compared to Ϫ1 and −10 cm 3 / mol observed experimentally. 38,39 All these values indicate close to perfect SI behavior and provide some confidence in the simulated rdfs.…”

The Kirkwood-Buff ͑KB͒ theory of solutions is a rigorous theory of solution mixtures which relates the molecular distributions between the solution components to the thermodynamic properties of the mixture. Ideal solutions represent a useful reference for understanding the properties of real solutions. Here, we derive expressions for the KB integrals, the central components of KB theory, in ideal solutions of any number of components corresponding to the three main concentration scales. The results are illustrated by use of molecular dynamics simulations for two binary solutions mixtures, benzene with toluene, and methanethiol with dimethylsulfide, which closely approach ideal behavior, and a binary mixture of benzene and methanol which is nonideal. Simulations of a quaternary mixture containing benzene, toluene, methanethiol, and dimethylsulfide suggest this system displays ideal behavior and that ideal behavior is not limited to mixtures containing a small number of components.
