Abstract
Density data for dilute aqueous solutions of six cyclic alcohols (cyclopentanol, cyclohexanol, cycloheptanol, cyclooctanol, cyclohexylmethanol, and 2-cyclohexylethanol) obtained using a flow vibrating-tube densimeter are presented together with partial molar volumes at infinite dilution (standard partial molar volumes) calculated from the measured data. The measurements were performed at temperatures from T = 298 K up to T = 373 K at pressures close to the atmospheric pressure [(0.4 to 0.5) MPa]. Trends in homologous series are discussed, and group contributions to standard partial molar volume are evaluated. Using the group contributions, standard partial molar volumes of three additional solutes were estimated and compared with data from the literature.
