ABSTRACT

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 1-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.
