Isothermal vapor鈥搇iquid equilibrium data for binary systems comprising perfluorobutane (R610) with methane (CH₄) or hydrogen sulfide (H₂S) were measured at isothermal conditions of approximately (293, 313, and 333) K, and pressures up to 9.837 MPa. The data were measured using a 鈥渟tatic-analytic鈥?apparatus equipped with a mobile pneumatic capillary sampler. The experimental data were correlated via the direct method using two sets of thermodynamic models. The Peng鈥揜obinson equation of state incorporating the Mathias鈥揅opeman 伪 function, with the Wong鈥揝andler mixing rule utilizing the nonrandom two-liquid activity coefficient model, was used for the correlation of the CH₄ + C₄F₁₀ system, while the Soave鈥揜edlich鈥揔wong equation of state incorporating the Mathias鈥揅opeman 伪 function, with the modified Huron鈥揤idal first-order mixing rule utilizing the nonrandom two-liquid activity coefficient model was used for the H₂S + C₄F₁₀ system.
