摘要: Densities of glycerol (1) + tert-butanol (2) mixtures were measured over the temperature range 293.15 to 348.15 K at atmospheric pressure, entire composition range, with a vibrating tube densimeter. Excess molar volumes, apparent and partial volumes tert-butanol, thermal isobaric expansivities mixture components calculated. The excess are negative all temperatures, deviations from ideality increase increasing temperature. fitted Redlich–Kister equation. Partial decrease concentration. dependence is characterized by an inversion x2≈0.7. “Negative expansion” limiting was observed.
