Densities for 1,2-ethanediol + 1-butanol, or 1-hexanol, or 1-octanol were measured over the entire composition range in the temperature range from (293.15 to 313.15) K at 5 K intervals. From the experimental values, the excess molar volumes and isobaric thermal expansibilities were calculated. The Redlich-Kister polynomials were fitted to the results, and smooth representations of the results are presented. In all cases, the positive values of the excess molar volumes were obtained for 1-hexanol and 1-octanol mixtures, whereas for I-butanol mixtures, negative values were observed. The experimental data were used also for the calculation by analytical differentiation of the isobaric coefficient of thermal expansion.
