ABSTRACT

Excess molar volumes VE m and partial molar volumes V2 were determined for dilute aqueous solutions of 1-propanol, 1,2-propanediol, 1,3-propanediol, and 1,2,3-propanetriol, at temperatures of (283.15, 288.15, 293.15, 298.15, 303.15, and 308.15) K from density measurements. The infinite dilution partial molar volumes V12 of alcohols in aqueous solution were obtained by extrapolation at each temperature. The volumetric behavior of aqueous alcohol and polyol solutions is discussed in terms of the relationship between polar and non-polar groups and its effect on water structure.
