Abstract Excess molar volumes V-m(E) and partial molar volumes (V) over bar (2) have been determined from density measurements for dilute aqueous solution of 1.2-hexanediol, 1.5-hexanediol, 1,6-hexanediol, and 2,5-hexanediol at (283.15, 288.15, 293.15, 298.15, 303.15, and 308.15) K as a function of composition. The infinite dilution partial molar volumes (V) over bar (infinity)(2) of alcohols in aqueous solution are evaluated through extrapolation. Interactions of the different solutes with water are discussed in terms of the effect of the position of the hydroxyl groups in the hexanediol molecule. The limiting slope of the partial molar volumes is interpreted in terms of alkanediol hydration. (c) 2007 Elsevier Ltd. All rights reserved.
