Abstract
Isothermal vapor-liquid equilibria at 338.15 K or 353.15 K for sulfola ne + 1-heptyne, + tetrahydrofuran, + 1,4-dioxane, + tetrachloromethane , and + 1,1,1-trichloroethane have been determined using an ebulliomet ric method. The excess molar Gibbs energies determined from the vapor- liquid equilibria are positive for all mixtures, with the maximum vary ing from 480 J . mol(-1) to 1550 J . mol(-1). The results reported are well correlated by the NRTL and UNIQUAC equations.
