ABSTRACT

Excess molar volumes VE,m of ternary mixtures containing {water + (1,2-propanediol, or 1,3-propanediol, or 1,2-butanediol, or 1,3-butanediol, or 1,4-butanediol, or 2,3-butanediol) + (sodium bromide, or ammonium bromide, or tetraethyl ammonium bromide, or 1-n-butyl-3-methylimidazolium bromide)} at 0.1 mol per kilogram of (water + alkanediol), as well as the excess molar volume of these aqueous mixtures salt-free, both at a temperature of 298.15 K and atmospheric pressure, have been determined as a function of composition using a glass pycnometer (5.0 cm3) with thermometer-in-glass. The VE,m are negative for all mixtures over the whole composition range. The influences of the electrolyte and of the hydrophobic and hydrophilic effects on the volumetric behavior are discussed.
