Abstract: | Excess molar volumes, V
m
E, and partial molar volumes, ↕
2, have been determined for dilute aqueous solutions of 1-butanol, 1,2-butanediol, 2,3-butanediol, 1,3-butanediol, 1,4-butanediol,
1,2,4-butanetriol and 1,2,3,4-butanetetrol (erythritol) at 298.15 K, as a function of composition from density measurements.
The limiting partial molar volumes, ↕
2∞, of alcohols in aqueous solution are evaluated through extrapolation. Interactions of the different solutes with water are
discussed in terms of the relationship among polar and non-polar groups on water structure and the effect of the position
of hydroxyl groups in the molecule. |
