ABSTRACT
Volatile organic compounds (VOCs), which find uses in industrial process need to be replaced, to decrease environmental pollution. Ionic liquids (ILs) are promising alternatives in industrial processes involving carboxylic acids. It is thus useful to study the interactions of ILs with organic acids on a laboratory scale. The combination of ILs with carboxylic acids will reduce the basicity and viscosity of ILs and thus make them suitable for many more applications in industrial processes. The thermo-physical properties namely density and speed of sound were measured for IL, [EPMpyr]+[SAL]-, and its two binary-mixtures with acetic and propionic acid. These thermophysical properties were measured at different temperatures, at 5 K intervals, ranging from T = (293.15 - 313.15) K. From these experimental values, thermodynamic parameters such as isentropic compressibility ( ), deviation in isentropic compressibility ( ) and excess molar volume ( ) were computed. It was found that and decreased with increasing temperatures and gave negative values for entire composition of both binary systems. These derived thermodynamic parameters ( & ) have been correlated using the Redlich-Kister model to obtain binary coefficients and standard errors.
