ABSTRACT

Excess molar volumes V E m for (1,3-dimethylimidazolidin-2-one + an alkan-1-ol from methanol to octan-1-ol) have been determined from density measurements at T = (283.15, 298.15, and 313.15) K over the whole composition range. The V E m values for the mixtures of 1,3-dimethylimidazolidin-2-one with methanol show the most negative ones at any composition and V E m values for (1,3-dimethylimidazolidin- 2-one + an alkan-1-ol) at each temperature varies systematically from negative to positive with an increase in carbon number m in alkan-1-ols. The m dependence of V E mox1 1/4 0:5P values for the equimolar mixtures of (1,3-dimethylimidazolidin-2-one + an alkan-1-ol) is very similar to that of (1,1,3,3-tetramethylurea + an alkan-1-ol) at 298.15 K. From the temperature dependence of V E mox1 1/4 0:5P values for the equimolar mixtures of 1,3-dimethylimidazolidin-2-one with an alkan-1-ol, the coefficient ooV E mox 1/4 0:5P=oT Pp was evaluated for each mixture and its dependence of m was also studied.
