Excess Gibbs Free Energies of Selected Binary Halogenated Silane Mixtures at 101.3KPa

Abstract

Prediction of the behavior of systems containing halogenated silanes required modification of the mixing rules used for solution models. In this work, interaction parameters for the characterization of binary systems of methylvinyldichlorosilane, methyltrichlorosilane, methyldichlorosilane and toluene at 101.3 kpa were evaluated accounting for the ideality of the vapor phase. The experimental measurements of liquid phase composition and bubble point temperature were found to be well represented by the Wilson model. Computed values of the vapor phase mole fractions, activity coefficients and excess Gibbs free energies from the model were presented and discussed.
