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.
