Abstract

ABSTRACT: Molar volumes and excess molar volumes were investigated from measured density values for {ethanol (1) + propylene glycol (2) + water (3)} ternary mixtures at temperatures from 293.15 K to 313.15 K. All the mixtures exhibit negative excess volumes probably due to increased interactions like hydrogen bonding and/or large differences in molar volumes of these three components. Thermal volume expansion coefficients were also calculated for ternary mixtures. Furthermore, the Jouyban-Acree model was used for density and molar volume correlations of the ternary mixtures at different temperatures. The mean relative deviations between experimental and back-calculated density and molar volume data were 0.06% and 0.30%, respectively.
