ABSTRACT

Values of the density for binary mixtures of propane-1,2-diol with methanol, propan-1-ol, hexan-1-ol, octan-1-ol, or nonan-1-ol were measured over the entire composition range and within the temperature range from (293.15 to 318.15) K by means of a vibrating tube densimeter. The excess molar volumes and limiting excess partial molar volumes were calculated. The Redlich Kister polynomials were fitted to the results and smooth representations of the results are presented. The negative values of the excess molar volumes over the entire composition and temperature ranges are observed in the case of methanol and propan-1-ol. In the cases of hexan-1-ol, octan-1-ol, and nonan-1-ol, positive values of the excess molar volumes over the entire composition and temperature ranges are observed. The effect of temperature is discussed qualitatively.
