Abstract
- The excess isentropic compressibilities of binary mixtures of 1-ethyl-3-methylimidazolium bis[(trifluoromethyl)sulfonyl]imide with ethyl acetate or methanol and 1-butyl-3-methylimidazolium bis[(trifluoromethyl)sulfonyl]imide with dimethyl sulfoxide or methanol were calculated based on thermodynamically rigorous ideal mixing rule. For the discussed mixtures, great differences between excess values of isentropic compressibilities and isentropic compressibility deviations from a simple mole fraction average of pure components isentropic compressibilities are observed. The usability and correctness of the Prigogine-Flory-Patterson (PFP) model for mixtures under test is discussed as well, because in constructing the PFP theory, hydrogen bonds and interactions of strong electrostatic nature are excluded [Fluid Phase Equilib. 233 (2005) 157].
