ABSTRACT

Densities for binary mixtures consisting of 1-butyl-3-methylimidazolium chloride ([bmim]Cl) and water or hydrophilic organic solvents (methanol, acetonitrile, and N,N-dimethylformamide) have been determined at different temperatures ranging from (293.15 to 318.15) K and atmospheric pressure, with mole fractions of [bmim]Cl in the mixtures ranging from 0 to about 0.5. The density values increase as the [bmim]Cl concentration increases or the temperature decreases, and the temperature dependence has been correlated by a second-order polynomial equation. The isobaric expansivity and apparent molar volume values for these binary mixtures have been calculated from the density data. A comparison has been made for the obtained properties with those of similar systems reported in the literature when available.
