Speed of sound and density data for dilute aqueous solutions of several alkane-α,ω-diols (ethane-1,2-diol, pentane-1,5-diol, hexane-1,6-diol, octane-1,8-diol, nonane-1,9-diol) were obtained using the Anton Paar DSA 5000 vibrating-tube densimeter and sound analyzer in the temperature range from (278.15 to 318.15) K and at atmospheric pressure. Standard molar isentropic compressions and standard molar volumes were evaluated from the measured data. Relations of the two standard quantities to the ratio between hydrophilic (hydroxyl groups) and hydrophobic (hydrocarbon chain) parts of the solute molecule are discussed. Contributions of the methylene group to the standard molar volume and standard molar isentropic compression are also evaluated.
