New vapor–liquid equilibrium (VLE) data for 1-propanethiol + 1-butanethiol + CH₄ ternary system is reported. Measurements were performed at three different temperatures (303, 336, and 368 K), and the pressure ranged from 1 to 9 MPa. The total system pressure was maintained by CH₄. The inlet mole fraction of 1-propanethiol (x = 5.43 × 10^–1) and 1-butanethiol (x = 4.56 × 10^–1) in the liquid phase were same in all experiments. A static analytic method was used for performing phase equilibrium measurements. The new VLE data have been modeled successfully with cubic-plus-association (CPA) equation of state.
