Vapor–Liquid Equilibrium Measurement of Methanol–Chloroform–Tetrahydrofuran and Methanol–Chloroform–Tetrahydrofuran–Dimethyl Sulfoxide Mixtures at 101.32 kPa

Abstract—The vapor–liquid equilibrium of methanol–chloroform–tetrahydrofuran mixtures of various compositions and methanol–chloroform–tetrahydrofuran–dimethyl sulfoxide mixtures with different dimethyl sulfoxide contents at 101.32 kPa were studied experimentally. A comparison of experimental and calculated values of the relative volatility of substances in four-component mixtures was carried out. The results of extractive distillation of ternary mixtures are predicted based on experimental data and calculated data obtained using the NRTL model.
