DEW AND BUBBLE POINT METHOD FOR TERNARY SYSTEMS

Methanol-Water-Dioxane System at 760 mm of Hg

抄録

By use of an apparatus previously proposed by the authors, dew and bubble points were measured at atmospheric pressure for the ternary system of methanol-water-dioxane. Vapor-liquid equilibrium relationships for the ternary system were calculated from the experimental dew and bubble points by applying the thermodynamic relations previously used for testing consistency. Equilibrium data for the system were also measured by using the Smith-Bonner still and compared with the calculated results. As a result, the estimated equilibrium values agreed fairly well with the experimental data and the reliability of the present method has been confirmed.
