ABSTRACT

The density, ?, and speed of sound, u, of methyl acetoacetate and ethyl acetoacetate in aqueous 1-butyl-3-methylimidazolium chloride [bmim][Cl] solutions have been measured in the temperature interval T = (288.15, 293.15, 298.15, 303.15, and 308.15) K and atmospheric pressure. The data has been used to calculate apparent molar volumes (V) and apparent molar adiabatic compressibility (K,s) of these mixtures. The standard partial molar volumes (V0), standard partial molar volumes of transfer (?V0), standard partial molar adiabatic compressibility (K,s0), and standard partial molar adiabatic compressibility (?K,s0) of transfer have been determined from these density and speed of sound data. The results have been interpreted in terms of solute solvent interactions. Later, the temperature dependence of the apparent molar volume has been used to calculate apparent molar expansivity E0 and the Hepler s constant values, (?2V0/?T2) to support the conclusions obtained from volumetric and speed of sound properties.
