doi:10.1016/j.cjche.2014.09.050

Abstract

Abstract: Thiswork provides amethod to explore the transport property of the electrolyte aqueous solutionswith one or two ionic liquids, especially focus on their electrical conductivity. The conductivities were measured for the ternary systems NaCl-[C₆mim][Cl] (1-hexyl-3-methylimidazolium chloride)-H₂O, [C₆mim][BF₄]-[C₆mim][Cl]-H₂O, NaNO₃-[C₆mim][BF₄](1-hexyl-3-methylimidazolium tetrafluoroborate)-H₂O, and [C₄mim][BF₄] (1-butyl-3- methylimidazolium tetrafluoroborate)-[C₆mim][BF₄]-H₂O, and their binary subsystems NaNO₃-H₂O, NaCl-H₂O, [C₆mim][BF₄]-H₂O, [C₆mim][Cl]-H₂O, and [C₄mim][BF₄]-H₂O, respectively. The conductivities of the ternary systems were also determined using generalized Young's rule and semi-ideal solution theory in terms of the data of their binary solutions. The comparison showed that the two simple equations provide good predictions for conductivity of mixed electrolyte solutions and the mixed ionic liquid solutions based on the conductivity of their binary subsystems.

摘要： Thiswork provides amethod to explore the transport property of the electrolyte aqueous solutionswith one or two ionic liquids, especially focus on their electrical conductivity. The conductivities were measured for the ternary systems NaCl–[C₆mim][Cl] (1-hexyl-3-methylimidazolium chloride)–H₂O, [C₆mim][BF₄]–[C₆mim][Cl]–H₂O, NaNO₃–[C₆mim][BF₄](1-hexyl-3-methylimidazolium tetrafluoroborate)–H₂O, and [C₄mim][BF₄] (1-butyl-3- methylimidazolium tetrafluoroborate)–[C₆mim][BF₄]–H₂O, and their binary subsystems NaNO₃–H₂O, NaCl–H₂O, [C₆mim][BF₄]–H₂O, [C₆mim][Cl]–H₂O, and [C₄mim][BF₄]–H₂O, respectively. The conductivities of the ternary systems were also determined using generalized Young's rule and semi-ideal solution theory in terms of the data of their binary solutions. The comparison showed that the two simple equations provide good predictions for conductivity of mixed electrolyte solutions and the mixed ionic liquid solutions based on the conductivity of their binary subsystems.
