Accurate measurements of boiling points and surface tensions of mixtures of benzyl acetate with dioxane, aniline, and meta-cresol over the entire range of concentration are reported. Results have been analyzed in terms of the quasi-crystalline model. It is possible to represent composition dependence of heats of mixing, boiling points, and surface tensions by means of equations obtained from this model using different parameter values for each property. The quasi-crystalline model to these systems is empirically applied.
