ABSTRACT

The densities, F, and the speeds of sound, u, for binary liquid mixtures containing 2-(2-hexyloxyethoxy)ethanol (C6E2) and n-butylamine (BA), dibutylamine (DBA), and tributylamine (TBA) have been measured as a function of composition using a vibrating tube densimeter and sound analyzer Anton-Paar model DSA- 5000 at temperatures (288.15, 293.15, 298.15, 303.15, and 308.15) K and atmospheric pressure. The F and u values were used to calculate excess molar volumes, Vm E , and excess molar isentropic compressibility, KS,m E , respectively. The Vm E and KS,m E values are shown to be negative for all the mixtures over the entire composition range. Both Vm E and KS,m E become more negative for all the mixtures with the rise of temperature. The change of Vm E and KS,m E with composition and temperature are discussed with a view to understand molecular interactions present in alkoxyethanol-alkylamine mixtures.
